Description

本発明は、獣類の侵入防止方法及び緑化構造物に関する。 The present invention relates to a method for preventing invasion of beasts and a greening structure.

多くの山岳地域において、近年急激にカモシカ、ニホンジカ類の密度が増大している。この現象に伴い、これらのシカ類による樹木の食害や、食害による表土の流出等の森林被害が拡大している。強い食害を受けた地域では、多くの植物が枯損し、棘のある植物やシカ類に有害な成分を含む植物しか残らないこともある。 In many mountain areas, the density of antelopes and sika deer has been increasing rapidly in recent years. Along with this phenomenon, damage to trees, such as damage to trees caused by these deer species and runoff of topsoil due to damage, is increasing. In areas that have been severely damaged, many plants may die, leaving only thorny plants or plants that contain harmful ingredients to deer.

緑化工が施された法面又は傾斜地にも、シカ類等の導入植物の採餌活動による食害及び引き抜き被害、施工地への侵入による生育基盤の踏み荒らし、これらに伴う生育基盤の弱体化や流出被害は多発している。このような被害にあった施工地は、導入植物の衰退が進行し、著しい場合は生育基盤が流出し、裸地化して再施工を余儀なくされる等、大きな問題となっている。 Even on slopes or slopes where greening has been applied, feeding damage and withdrawal damage due to foraging activities of introduced plants such as deer, treading of the growth base due to entry into the construction site, weakening of the growth base accompanying these Outflow damage is frequent. Construction sites that have suffered such damages are a major problem, such as the decline of the introduced plant, and if it is remarkable, the growth base flows out, making it bare and forced to reconstruct.

このような緑化工施工地の被害は、培土等を法面等に吹付ける植生基材吹付工のような工種だけでなく、広く普及している吹付枠工を併用した緑化工施工地においても同様に発生している。吹付枠工を施工した法面又は傾斜地に対しては、枠の上面や周囲に金網や合成樹脂製のネットを設置して、獣類の侵入を防止する方法がある（例えば、特許文献１参照）。
特開２０００−１６６４５７号公報 Such damage to the revegetation construction site is not limited to the type of vegetation base material spraying method that sprays soil, etc. on the slope, etc., but also in the revegetation construction site that uses a widespread spray frame work together. It is occurring as well. For slopes or slopes where spray frame work has been performed, there is a method for preventing invasion of beasts by installing a wire net or a net made of synthetic resin on the upper surface or the periphery of the frame (for example, see Patent Document 1). .
JP 2000-166457 A

ところが、金網を設置する方法は、侵入防止効果は高いが、法枠が形成された斜面全体に金網を張設することになるため、コストが高くなる。合成樹脂製のネットは、紫外線による劣化が急速で、効果の持続期間が短いだけでなく、破損すると景観上見苦しい。さらに、これらの網を敷設する方法は、法枠工の景観を損なうだけでなく、長期間経過後、網を構成する鋼材等が腐蝕したときに撤去費も多大となる。 However, the method of installing the wire mesh has a high intrusion prevention effect, but the cost increases because the wire mesh is stretched over the entire slope where the legal frame is formed. Synthetic resin nets are rapidly deteriorated by ultraviolet rays, and the duration of the effect is short. Furthermore, the method of laying these nets not only impairs the landscape of the frame work, but also increases the removal costs when the steel materials constituting the net are corroded after a long period of time.

本発明は、上記問題点に鑑みてなされたものであり、その目的は、獣類の侵入を防止する侵入防止方法及び緑化構造物を提供することにある。 This invention is made | formed in view of the said problem, The objective is to provide the invasion prevention method and greening structure which prevent invasion of animals.

上記問題点を解決するために、請求項１に記載の発明は、法枠が形成された緑化構造物への獣類の侵入防止方法であって、獣類の侵入を防止するための線材を、前記法枠を構成する梁と梁との間に張ることを要旨とする。 In order to solve the above-mentioned problems, the invention described in claim 1 is a method for preventing the invasion of animals to a greening structure in which a legal framework is formed, wherein the wire rod for preventing the invasion of animals is The gist is to stretch between the beams that make up the frame.

請求項２に記載の発明は、請求項１に記載の獣類の侵入防止方法において、複数の前記線材を、間隔を保持して平行に配置することを要旨とする。
請求項３に記載の発明は、請求項１又は２に記載の獣類の侵入防止方法において、複数の前記線材を、互いに接近する方向への移動を規制して配設することを要旨とする。 The gist of the invention described in claim 2 is that, in the method for preventing invasion of animals according to claim 1, a plurality of the wire rods are arranged in parallel at intervals.
The gist of the invention described in claim 3 is that, in the method for preventing invasion of beasts according to claim 1 or 2, the plurality of wires are arranged by restricting movement in a direction approaching each other.

請求項４に記載の発明は、法枠が形成された緑化構造物であって、前記法枠を構成する梁と梁との間に配設された線材を備えたことを要旨とする。
請求項５に記載の発明は、請求項４に記載の緑化構造物において、複数の前記線材の間に、環状部を設けたことを要旨とする。 The invention according to claim 4 is a greening structure in which a frame is formed, and is provided with a wire disposed between the beams constituting the frame.
The invention according to claim 5 is summarized in that in the greening structure according to claim 4, an annular portion is provided between the plurality of wires.

請求項６に記載の発明は、請求項４又は５に記載の緑化構造物において、複数の前記線材の間に、前記各線材の互いに接近する方向への移動を規制する間隔保持部材を設けたことを要旨とする。 According to a sixth aspect of the present invention, in the greening structure according to the fourth or fifth aspect, an interval holding member is provided between the plurality of the wire rods to restrict the movement of the wire rods toward each other. This is the gist.

請求項７に記載の発明は、請求項４〜６のいずれか１項に記載の緑化構造物において、前記法枠を構成する前記梁の上に、突起部を備えたことを要旨とする。 The gist of the invention described in claim 7 is that, in the greening structure according to any one of claims 4 to 6, a protrusion is provided on the beam constituting the frame.

請求項１又は４に記載の発明によれば、線材を、法枠を構成する梁と梁の間に張る。このため、獣類が緑化構造物に侵入した際に、獣類の足と線材とが接触せざるを得なくなり、獣類の警戒心を煽ることができる。又は、獣類が、線材を警戒して緑化構造物への侵入を回避する。従って、獣類により、法枠内に生育した植物が採食される、いわゆる食害を防止することができる。また、獣類が、法枠内の客土層の上を歩き回るのを防止できるため、法枠内に生育した植物が踏み荒らされるのを防止できる。 According to invention of Claim 1 or 4, a wire is stretched between the beams which comprise a frame. For this reason, when the beast invades the greening structure, the foot of the beast and the wire have to come into contact with each other, and the beware of the beast can be raised. Or beasts watch out for a wire and avoid intrusion to a greening structure. Therefore, it is possible to prevent so-called food damage, in which a plant that has grown within the legal framework is eaten by a beast. In addition, since it is possible to prevent the animals from walking on the soil layer within the legal framework, it is possible to prevent the plants grown in the legal framework from being treaded.

請求項２の発明によれば、複数の線材を間隔を保持して平行に配設する。このため、獣類が緑化構造物に侵入する際には、複数の線材を跨ぐか、線材の間に足を踏み入れなければならないので、緑化構造物への侵入を困難にすることができる。 According to invention of Claim 2, a some wire is arrange | positioned in parallel, maintaining a space | interval. For this reason, when a beast invades a greening structure, it is necessary to straddle a plurality of wire rods or to step in between the wire rods, making it difficult to enter the greening structure.

請求項３に記載の発明によれば、線材の互いに接近する方向を規制する。このため、外力が加えられることにより線材が近接することがない。従って、各線材の間の間隔を、適度な長さに保持することにより、侵入防止効果を持続させることができる。 According to the invention described in claim 3, the direction in which the wires approach each other is regulated. For this reason, a wire does not adjoin by external force being applied. Therefore, the intrusion prevention effect can be maintained by keeping the distance between the wires to an appropriate length.

請求項５に記載の発明によれば、複数の線材の間に環状部が配設される。このため、線材の間に足を入れた獣類が、線材と平行な方向への歩行を試みた場合に、環状部が獣類の足に引っ掛かる。このため、獣類による、線材と平行な方向への歩行を抑制できる。 According to invention of Claim 5, an annular part is arrange | positioned between several wire. For this reason, when a beast with a foot placed between the wire rods tries to walk in a direction parallel to the wire rod, the annular portion is caught on the foot of the beast. For this reason, the walk in the direction parallel to a wire by a beast can be suppressed.

請求項６に記載の発明によれば、複数の線材の間に、間隔保持部材を設けた。従って、各線材の間の間隔を、適度な長さに保持することにより、侵入防止効果を持続させることができる。 According to the invention described in claim 6, the spacing member is provided between the plurality of wires. Therefore, the intrusion prevention effect can be maintained by keeping the distance between the wires to an appropriate length.

Even if a beast tries to walk on the beam avoiding the wire or climbs over the beam, the protrusion can prevent the greening structure from entering.

以下、本発明を具体化した一実施形態を図１〜図６に従って説明する。図１は、緑化工を完了した傾斜面を有する地山の説明図である。図２及び図３は、同地山の部分側面図、図４は、図２におけるＡ−Ａ線における地山の断面要部を示している。図５は、同地山の要部斜視図である。 Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. Drawing 1 is an explanatory view of a natural ground which has an inclined surface which completed revegetation work. 2 and 3 are partial side views of the ground mountain, and FIG. 4 shows a cross-sectional main part of the ground mountain along the line AA in FIG. FIG. 5 is a perspective view of an essential part of the mountain.

図１に示すように、地山１に形成された法面２は、上端から道路Ｒに接する下端まで全面が傾斜しており、多数の法枠３からなる緑化工基盤４が形成されている。法枠３は、法面２上に升目状に形成され、法面２の高さ方向（図１中Ｙ２方向）の列及び水平方向（Ｘ２方向）の行を成している。法枠３を形成する際は、地山の滑落を防止する金網上に組立枠を組立て、その組立枠にモルタルを吹付ける。そして、吹付けたモルタルを硬化させることにより、略四角枠状の法枠３が形成される。 As shown in FIG. 1, the slope 2 formed on the natural ground 1 is inclined entirely from the upper end to the lower end in contact with the road R, and a revegetation base 4 composed of a number of slope frames 3 is formed. . The slope frame 3 is formed in a grid shape on the slope 2 and forms columns in the height direction (Y2 direction in FIG. 1) and rows in the horizontal direction (X2 direction). When forming the frame 3, an assembly frame is assembled on a wire mesh that prevents the natural ground from falling, and mortar is sprayed on the assembly frame. Then, by curing the sprayed mortar, a substantially rectangular frame-shaped method frame 3 is formed.

また、図２に示すように、法枠３は、法面２に沿った水平方向（Ｘ２方向）にほぼ平行
に形成された横梁３ａと、法面２に沿った高さ方向（Ｙ２方向）にほぼ平行に形成された縦梁３ｂとから形成されている。これらの横梁３ａ及び縦梁３ｂの地山１の地肌１ａからの高さは、１５０〜３００ｍｍになっている。また、横梁３ａ、縦梁３ｂ及び地肌１ａから構成される空間である植生材収容部６の横幅及び縦幅は、１７００ｍｍ程度になっている。 In addition, as shown in FIG. 2, the frame 3 includes a cross beam 3a formed substantially parallel to the horizontal direction (X2 direction) along the slope 2 and a height direction (Y2 direction) along the slope 2. And a vertical beam 3b formed substantially in parallel with each other. The height of the horizontal beam 3a and the vertical beam 3b from the ground surface 1a of the natural ground 1 is 150 to 300 mm. Moreover, the horizontal width and the vertical width of the vegetation material accommodating part 6 which are the space comprised from the horizontal beam 3a, the vertical beam 3b, and the ground surface 1a are about 1700 mm.

法面２上に法枠３を形成すると、図４に示すように、三角柱状に形成された滞留防止部材５を、横梁３ａの上側面３ｆに沿って配設する。即ち、法枠３を構成する横梁３ａのうち、横梁３ａの上側面３ｆには雨水が滞留しやすく、植物の根腐れ、地山１の浸食等が発生しやすい。このため、横梁３ａの上側面３ｆと地肌１ａとの間で構成される空間を、断面三角状の滞留防止部材５で埋めることによって、この空間の雨水の滞留を防止する。また、横梁３ａと地肌１ａとの間に配設された滞留防止部材５の上面５ａは、ほぼ水平となり、その幅が、およそ２８０〜４５０ｍｍになる。 When the method frame 3 is formed on the slope 2, as shown in FIG. 4, the stay prevention member 5 formed in a triangular prism shape is disposed along the upper side surface 3 f of the transverse beam 3 a. That is, among the horizontal beams 3a constituting the frame 3, rainwater tends to stay on the upper side surface 3f of the horizontal beams 3a, and plant root rot and erosion of the natural ground 1 are likely to occur. For this reason, the space formed between the upper side surface 3f of the horizontal beam 3a and the ground 1a is filled with the stay prevention member 5 having a triangular cross section, thereby preventing the rainwater from staying in this space. Moreover, the upper surface 5a of the stay prevention member 5 disposed between the cross beam 3a and the ground 1a is substantially horizontal, and the width thereof is approximately 280 to 450 mm.

滞留防止部材５を配設すると、植生材収容部６に、混練物を吹付ける。混練物は、培土、バーク堆肥等の土壌改良剤、肥料、接合剤、及び種子等を混合して作成する。そして、この混練物をスクイズポンプ又は圧縮空気等を使用して植生材収容部６に吹付ける。 When the stay prevention member 5 is disposed, the kneaded material is sprayed onto the vegetation material accommodating portion 6. The kneaded material is prepared by mixing soil improver such as cultivating soil, bark compost, fertilizer, bonding agent, seeds and the like. And this kneaded material is sprayed on the vegetation material accommodating part 6 using a squeeze pump or compressed air.

植生材収容部６に吹付けられた混練物は、図２及び図４に示すように、地肌１ａに積層されて、生育基盤７を形成する。生育基盤７は、例えば５０ｍｍ等、植物が生育できるだけの厚みを有している。 As shown in FIGS. 2 and 4, the kneaded material sprayed on the vegetation material container 6 is stacked on the ground 1 a to form a growth base 7. The growth base 7 has a thickness that allows the plant to grow, for example, 50 mm.

生育基盤７を植生材収容部６内に形成すると、図１に示すように、獣類の侵入を防止するための第１及び第２の線材８，９を緑化工基盤４に配設する。この第１及び第２の線材８，９は、緑化工基盤４の上端及び下端と、左側端及び右側端等、緑化工基盤４の各端の法枠３に対して張設される。 When the growth base 7 is formed in the vegetation material container 6, first and second wire rods 8 and 9 for preventing the invasion of beasts are disposed on the revegetation base 4 as shown in FIG. The first and second wire rods 8 and 9 are stretched with respect to the frame 3 at each end of the greening substrate 4 such as the upper and lower ends of the greening substrate 4 and the left and right ends.

例えば、図１に示すように、緑化工基盤４の下端の３行の各法枠３と、上端の３行の各法枠３に対し、第１及び第２の線材８，９を各横梁３ａ（Ｘ２方向）に平行に張設する。第１及び第２の線材８，９は、金属製の線材であって、図２に示すように、１つの法枠３を構成する各縦梁３ｂの間に亘って、縦梁３ｂの上面３ｇに沿って、接触させて配設する。また、緑化工基盤４の左端の３列の各法枠３と、右端の３列の各法枠３に対して、第１及び第２の線材８，９を縦梁３ｂ（Ｙ２方向）と平行に張設する。図３に示すように、縦梁３ｂと平行な第１及び第２の線材８，９は、各横梁３ａの間に亘って、横梁３ａの上面３ｈに沿って張設する。尚、図２は、下端３行を構成する各法枠３、図３は、右端３列を構成する各法枠３を図示している。 For example, as shown in FIG. 1, the first and second wire rods 8 and 9 are attached to the horizontal beams 3 and 3 in the lower row of the greening base 4 and the horizontal frames 3 in the upper and lower rows, respectively. 3a (X2 direction) is stretched in parallel. The first and second wire rods 8 and 9 are metal wire rods, and as shown in FIG. 2, the upper surface of the vertical beam 3 b extends between the vertical beams 3 b constituting one normal frame 3. Arrange along 3g in contact. In addition, the first and second wire rods 8 and 9 are connected to the longitudinal beams 3b (Y2 direction) with respect to the three vertical frames 3 of the left end of the greening foundation 4 and the horizontal frames 3 of the rightmost three rows. Stretch in parallel. As shown in FIG. 3, the 1st and 2nd wire 8 and 9 parallel to the vertical beam 3b is stretched along the upper surface 3h of the horizontal beam 3a across each horizontal beam 3a. 2 shows each frame 3 constituting the bottom three rows, and FIG. 3 shows each frame 3 constituting the right three columns.

下端から３行の法枠３に対して第１及び第２の線材８，９を張設する際は、図４に示すように、第１の線材８を、横梁３ａの角頂部３ｅから、水平方向（法面２に対して奥行き方向、図４中Ｘ１方向）に長さＬ１、鉛直方向（重力方向、図４中Ｙ１方向）に高さＨ１の位置に、縦梁３ｂの上面に沿って張設する。このとき、図１に示すように、第１の線材８の両端を、地山１に打ち込んだアンカーピンＰに固定する。尚、法面２の傾斜角は、本実施形態では４５度以上を想定している。 When stretching the first and second wire rods 8 and 9 with respect to the frame 3 of the three rows from the lower end, as shown in FIG. 4, the first wire rod 8 is pulled from the corner apex portion 3e of the cross beam 3a. Along the upper surface of the vertical beam 3b at a position of a height L1 in the horizontal direction (depth direction with respect to the slope 2, direction X1 in FIG. 4) and a height H1 in the vertical direction (gravity direction, direction Y1 in FIG. 4). To stretch. At this time, as shown in FIG. 1, both ends of the first wire 8 are fixed to anchor pins P driven into the natural ground 1. The inclination angle of the slope 2 is assumed to be 45 degrees or more in this embodiment.

長さＬ１は、第１の線材８が、滞留防止部材５の上方に配置される長さに設定されている。さらに、この長さＬ１は、ニホンジカ等の偶蹄目類に代表される獣類が角頂部３ｅに足を掛けた状態で、滞留防止部材５又は植生材収容部６を踏み込む場合の歩幅（４００〜８００ｍｍ）よりも小さくなるように設定され、本実施形態では、長さＬ１は、７０〜１２０ｍｍであって、この範囲内で法面２の傾斜角等に応じて設定される。７０ｍｍよりも小さくすると、角頂部３ｅと第１の線材８との距離が過小となり、獣類が第１の線材８を
容易に跨いで、滞留防止部材５の上に足を置くようになる。１２０ｍｍよりも大きいと、第１の線材８に触れることなく、滞留防止部材５の上に足を掛けてしまう。 The length L <b> 1 is set to a length at which the first wire 8 is disposed above the stay prevention member 5. Furthermore, this length L1 is a stride (400 to 800 mm) when a beast such as a sika deer stepped on the stay prevention member 5 or the vegetation material storage unit 6 in a state where a beast lies on the apex 3e. In this embodiment, the length L1 is 70 to 120 mm, and is set in accordance with the inclination angle of the slope 2 within this range. If it is smaller than 70 mm, the distance between the corner apex 3e and the first wire 8 becomes too small, and the animal can easily straddle the first wire 8 and put their feet on the stay prevention member 5. If it is larger than 120 mm, the first wire 8 is not touched and the foot is put on the stay prevention member 5.

高さＨ１は、本実施形態では、１００〜２００ｍｍである。第１の線材８の高さＨ１が１００ｍｍよりも低いと、獣類が容易に第１の線材８を跨いでしまう。高さＨ１が２００ｍｍよりも大きいと、上記したように、第１の線材８に接触することなく、例えば滞留防止部材５等、第１の線材８の手前を踏み込んでしまう。 The height H1 is 100 to 200 mm in this embodiment. If the height H1 of the first wire 8 is lower than 100 mm, the beast easily straddles the first wire 8. If the height H1 is greater than 200 mm, as described above, the front of the first wire 8 such as the stay prevention member 5 is stepped on without contacting the first wire 8.

このように第１の線材８を配置すると、獣類が滞留防止部材５の上面５ａ等に足を掛けた際に、第１の線材８が、ニホンジカ等の足のうち、蹄よりも上方の部位に接触する。獣類の足に第１の線材８が接触すると、獣類は警戒して、接触を避けようとする。このため、動作が困難になり、生育基盤７への侵入が難しくなる。また、法面２の傾斜が大きくなるほど獣類の歩行の容易な幅が小さくなるため、傾斜角が大きくなるほど長さＬ１，Ｌ２を小さくする。 When the first wire 8 is arranged in this way, when the animal puts his or her foot on the upper surface 5a of the stay prevention member 5, the first wire 8 is a part of the foot such as sika deer above the hoof. To touch. When the first wire 8 comes into contact with the leg of the beast, the beast is alert and tries to avoid contact. For this reason, operation | movement becomes difficult and the penetration | invasion to the growth base 7 becomes difficult. Moreover, since the easy width of a beast's walk becomes small, so that the slope of slope 2 becomes large, length L1, L2 is made small, so that an inclination angle becomes large.

第２の線材９は、図４に示すように、横梁３ａの角頂部３ｅから、水平方向（Ｘ１方向）に長さＬ２、鉛直方向（Ｙ１方向）に高さＨ２の位置に配置し、その両端を地山１に打ち込んだアンカーピンＰに固定する。本実施形態では、長さＬ２は、２００〜４５０ｍｍに設定されている。長さＬ２が２００ｍｍよりも小さいと、ニホンジカ等の獣類が第１及び第２の線材８，９の間を一度に乗り越えて、生育基盤７を容易に踏み込む。長さＬ２が４５０ｍｍよりも大きいと第１の線材８との間隔が過大となり、第１及び第２の線材８，９の間を踏み込んでも、獣類の足と第１又は第２の線材８，９と接触しないことがある。 As shown in FIG. 4, the second wire 9 is arranged at a position of a length L2 in the horizontal direction (X1 direction) and a height H2 in the vertical direction (Y1 direction) from the top 3e of the cross beam 3a. Both ends are fixed to the anchor pin P driven into the natural ground 1. In the present embodiment, the length L2 is set to 200 to 450 mm. When the length L2 is smaller than 200 mm, beasts such as sika defeat the space between the first and second wire rods 8 and 9 at a time and easily step on the growth base 7. If the length L2 is greater than 450 mm, the distance between the first wire 8 and the first wire 8 will be excessive, and even if the distance between the first and second wires 8 and 9 is stepped on, the foot of the animal and the first or second wire 8, 9 may not contact.

高さＨ２は、本実施形態では、４２０〜５５０ｍｍになっている。高さＨ２が４２０ｍｍよりも低いと、上記したように、第１及び第２の線材８，９を一度に乗り越えやすい。高さＨ２が５５０ｍｍよりも大きいと、上記したように、第１及び第２の線材８，９の間を踏み込みやすい。このように第１及び第２の線材８，９を各法枠３に対して張設すると、第１及び第２の線材８，９は、地山１の地肌１ａに対して、ほぼ１５０〜３００ｍｍ離間した状態になる。 In the present embodiment, the height H2 is 420 to 550 mm. If the height H2 is lower than 420 mm, it is easy to get over the first and second wire rods 8 and 9 at a time as described above. When the height H2 is larger than 550 mm, it is easy to step between the first and second wire rods 8 and 9 as described above. When the first and second wire rods 8 and 9 are thus stretched with respect to each frame 3, the first and second wire rods 8 and 9 are approximately 150 to the ground surface 1 a of the natural ground 1. It will be 300mm apart.

第１及び第２の線材８，９を配設すると、第１及び第２の線材８，９の間に、各法枠３に対して１個の割合で間隔保持部材１０を配置する。図５及び図６に示すように、間隔保持部材１０は、円環状に形成された線材からなる環状部１１と、環状部１１の一部に設けられた支持部１２とを備えている。支持部１２は、合成樹脂等からなり、環状部１１に取付けられた取付部１３と、１対の規制部１４とを備えている。規制部１４は、環状部１１の内側を向くように配置されている。 When the first and second wire rods 8 and 9 are disposed, the spacing member 10 is disposed between the first and second wire rods 8 and 9 at a ratio of one for each of the frame 3. As shown in FIGS. 5 and 6, the spacing member 10 includes an annular portion 11 made of a wire formed in an annular shape, and a support portion 12 provided on a part of the annular portion 11. The support portion 12 is made of synthetic resin or the like, and includes an attachment portion 13 attached to the annular portion 11 and a pair of restriction portions 14. The restricting portion 14 is disposed so as to face the inside of the annular portion 11.

間隔保持部材１０は、環状部１１内に挿通した第１及び第２の線材８，９間に、支持部１２に設けた１対の規制部１４を介在させることにより、第１及び第２の線材８，９の互いに接近する方向への移動を規制する。尚、この間隔保持部材１０は、第１及び第２の線材８，９を張設する前に、予め第１及び第２の線材８，９に通しておいても良い。又は間隔保持部材１０の取付部１３を開閉可能に構成し、開状態にした取付部１３から既に張設した第１及び第２の線材８，９を、環状部１１の内側に通すようにしてもよい。 The spacing member 10 is configured such that a pair of restricting portions 14 provided on the support portion 12 are interposed between the first and second wire rods 8 and 9 that are inserted into the annular portion 11. The movement of the wires 8 and 9 in the direction approaching each other is restricted. The spacing member 10 may be passed through the first and second wires 8 and 9 in advance before the first and second wires 8 and 9 are stretched. Alternatively, the attachment portion 13 of the spacing member 10 is configured to be openable and closable, and the first and second wire members 8 and 9 already stretched from the attachment portion 13 in the open state are passed through the inside of the annular portion 11. Also good.

さらに、間隔保持部材１０は、取付部１３の下面で第１及び第２の線材８，９に支持されるので、振子状態となる。このため、ニホンジカ等の獣類が、間隔保持部材１０に接触すると、間隔保持部材１０が揺動するので、獣類を警戒させることができる。また、獣類が第１及び第２の線材８，９の間に足を差し込み、横方向（Ｘ２方向）への移動を試みた場合、蹄が環状部１１の中に引っ掛かるので、横歩きを抑制することができる。また、横歩きを行ったとしても、各法枠３に対して１個の間隔保持部材１０が、例えば１７００ｍ
ｍの間隔で配置されているので、複数の法枠３に亘る横歩きを防止できる。 Furthermore, since the space | interval holding member 10 is supported by the 1st and 2nd wire rods 8 and 9 in the lower surface of the attaching part 13, it will be in a pendulum state. For this reason, when a beast such as a sika deer contacts the interval holding member 10, the interval holding member 10 swings, so that the beast can be warned. In addition, when a beast inserts a foot between the first and second wire rods 8 and 9 and tries to move in the lateral direction (X2 direction), the hoof is caught in the annular portion 11, thereby suppressing lateral walking. can do. Further, even if a side walk is performed, one spacing member 10 is provided for each frame 3 to 1700 m, for example.
Since it is arrange | positioned at the space | interval of m, the side walk over the some frame 3 can be prevented.

このように、緑化工基盤４のうち下端の３行の法枠３に第１及び第２の線材８，９を張設すると、上端の３行の法枠３に対しても第１及び第２の線材８，９を張設する。このとき、図１に示すように、第１の線材８を、法枠３を構成する２つの横梁３ａのうち、下側の横梁３ａの角頂部３ｅから、長さＬ１の位置に配置し、第２の線材９を、その角頂部３ｅから長さＬ２の位置に配置する。 As described above, when the first and second wire rods 8 and 9 are stretched on the bottom three rows of the frame 3 in the greening base 4, the first and second rows of the top frames 3 are also arranged. 2 wires 8 and 9 are stretched. At this time, as shown in FIG. 1, the first wire 8 is arranged at a position of a length L1 from the top 3e of the lower horizontal beam 3a among the two horizontal beams 3a constituting the normal frame 3, The 2nd wire 9 is arrange | positioned in the position of length L2 from the corner | angular top part 3e.

また、同様に、緑化工基盤４の各側端に形成された３列の法枠３に対して、縦梁３ｂと平行に第１及び第２の線材８，９を張設する。例えば、図３に示すように、右端の列の各法枠３に対して、第１の線材８を、第２の線材９よりも外側（右側）になるように張設する。このとき、第１の線材８は、各縦梁３ｂのうち、外側（右側）の縦梁３ｂの角頂部３ｅから水平方向（Ｘ２方向）の長さＬ１の位置に張設する。また、第２の線材９は、縦梁３ｂの角頂部３ｅから長さＬ２の位置に張設する。第１及び第２の線材８，９を張設すると、その間に間隔保持部材１０を配設する。 Similarly, the first and second wire rods 8 and 9 are stretched in parallel with the longitudinal beam 3b with respect to the three rows of the frame 3 formed on each side end of the greening base 4. For example, as shown in FIG. 3, the first wire 8 is stretched to the outside (right side) of the second wire 9 with respect to each frame 3 in the rightmost column. At this time, the 1st wire 8 is stretched in the position of length L1 of the horizontal direction (X2 direction) from the top part 3e of the outer (right side) vertical beam 3b among each vertical beam 3b. Moreover, the 2nd wire 9 is stretched in the position of length L2 from the square top part 3e of the vertical beam 3b. When the first and second wire rods 8 and 9 are stretched, the spacing member 10 is disposed therebetween.

これにより、緑化工基盤４の側端から侵入しようとする獣類が、縦梁３ｂと平行に張設された第１及び第２の線材８，９を一度に乗り越えたり、第１及び第２の線材８，９の間を踏み込んだ際に、獣類の足と第１又は第２の線材８，９が接触しやすくなる。また、第１及び第２の線材８，９との接触を回避しようとすると、動作が不安定となるため、獣類は侵入に消極的になる。 As a result, the beasts trying to invade from the side edge of the revegetation base 4 get over the first and second wire rods 8 and 9 stretched in parallel with the vertical beam 3b at a time, or the first and second When the space between the wire rods 8 and 9 is stepped on, the leg of the animal and the first or second wire rods 8 and 9 can easily come into contact with each other. Further, if the contact with the first and second wire rods 8 and 9 is to be avoided, the operation becomes unstable, so that the beast is reluctant to enter.

このように上端、下端及び側端に第１及び第２の線材８，９を張設すると、第１及び第２の線材８，９を張設していない法枠３が、第１及び第２の線材８，９を張設した法枠３に取り囲まれた状態になる。 Thus, when the first and second wire rods 8 and 9 are stretched at the upper end, the lower end and the side ends, the frame 3 without the first and second wire rods 8 and 9 is stretched. It will be in the state surrounded by the method frame 3 which stretched the 2 wire rods 8 and 9. FIG.

第１及び第２の線材８，９及び間隔保持部材１０を配設すると、図５に示すように、第１及び第２の線材８，９の途中に、突起部１５を配設する。突起部１５は、４本の線材から構成され、本実施形態では四角錐状をなしている。また、突起部１５の高さは、３００ｍｍ程度になっている。この突起部１５は、横梁３ａに平行に張設された第１及び第２の線材８，９に対して固定され、縦梁３ｂ上に配置される。また、縦梁３ｂに平行に張設された第１及び第２の線材８，９に対して固定された突起部１５は、横梁３ａの上に配置される。例えば、ニホンジカ等の獣類が、横梁３ａと平行に張設された第１及び第２の線材８，９を避けて、縦梁３ｂを駆け上がろうとした場合には、この突起部１５に足を引っ掛ける。又は、この突起部１５を警戒して、縦梁３ｂに沿った移動を中止する。 When the first and second wire rods 8 and 9 and the spacing member 10 are disposed, the protrusion 15 is disposed in the middle of the first and second wire rods 8 and 9, as shown in FIG. The protrusion 15 is composed of four wires, and in the present embodiment, has a quadrangular pyramid shape. Moreover, the height of the protrusion 15 is about 300 mm. The protrusion 15 is fixed to the first and second wire rods 8 and 9 extending in parallel to the horizontal beam 3a and is disposed on the vertical beam 3b. In addition, the protrusion 15 fixed to the first and second wire rods 8 and 9 stretched in parallel to the vertical beam 3b is disposed on the horizontal beam 3a. For example, when a beast such as sika deer tries to run up the vertical beam 3b while avoiding the first and second wires 8 and 9 stretched in parallel with the horizontal beam 3a, Hook. Alternatively, the projection 15 is warned and the movement along the vertical beam 3b is stopped.

これらの工程を経て完成した緑化工基盤４は、法枠３に金網を敷設する場合に比べ、第１及び第２の線材８，９が目立たないので、緑化工基盤４の景観に悪影響を与えない。また、第１及び第２の線材８，９は、縦梁３ｂ又は横梁３ａに対して離間させるのではなく、縦梁３ｂ又は横梁３ａに沿って張設するだけで、生育基盤７に対して離間した状態となる。このため、施工が容易となるとともに、獣類が侵入した際に、第１及び第２の線材８，９と、獣類の蹄から上の部位とを主に接触させて、警戒心又は不快感を煽ることができる。 The revegetation base 4 completed through these processes has a negative effect on the landscape of the revegetation base 4 because the first and second wire rods 8 and 9 are not conspicuous compared to the case where a wire mesh is laid in the frame 3. Absent. Further, the first and second wire rods 8 and 9 are not separated from the vertical beam 3b or the horizontal beam 3a, but are merely stretched along the vertical beam 3b or the horizontal beam 3a, so that the growth base 7 is It is in a separated state. For this reason, construction becomes easy, and when the animal invades, the first and second wire rods 8 and 9 and the part above the hoof of the animal are mainly brought into contact with each other, so that warning or discomfort is caused. I can talk.

そして、ニホンジカ等の偶蹄目類に代表される獣類が、完成した緑化工基盤４の上端、下端又は側端から侵入する場合、法枠３の角頂部３ｅ等に足を掛けて、第１及び第２の線材８，９の間を踏み込んだり、第１及び第２の線材８，９を跨ごうと試みる。しかし、足、蹄、副蹄が第１及び第２の線材８，９のいずれかに接触せざるを得なくなるので、獣類は、急傾斜の場所で不安定な行動を余儀なくされ、緑化工基盤４への侵入に消極的となり、侵入頻度が大きく減少する。 And, when a beast represented by an artiodactyl such as sika deer invades from the upper end, lower end or side end of the completed greening construction base 4, the first and An attempt is made to step in between the second wires 8 and 9 or straddle the first and second wires 8 and 9. However, since the foot, hoof, and auxiliary hoof are forced to contact one of the first and second wire rods 8 and 9, the beasts are forced to behave unstablely at steep places, and the planting base 4 is reluctant to intrude into 4 and the intrusion frequency is greatly reduced.

また、第１及び第２の線材８，９への接触を回避するために、縦梁３ｂ又は横梁３ａ上の歩行を試みた場合、縦梁３ｂ上に配置された突起部１５に足が引っ掛かる。又は、突起部１５を回避しようとすると、不安定な動作となる。このため、緑化工基盤４への侵入頻度が減少する。さらに、獣類が第１及び第２の線材８，９の間の横歩き（又は縦歩き）を試みた場合にも、間隔保持部材１０の環状部１１に足を引っ掛けるので、横歩き（又は縦歩き）を中止する。 In addition, when trying to walk on the vertical beam 3b or the horizontal beam 3a in order to avoid contact with the first and second wire rods 8 and 9, the foot is caught by the protrusion 15 arranged on the vertical beam 3b. . Or if it tries to avoid the projection part 15, it will become unstable operation | movement. For this reason, the frequency of intrusion into the greening base 4 is reduced. Further, when the animal tries to walk sideways (or vertically walk) between the first and second wire rods 8 and 9, the leg is hooked on the annular portion 11 of the spacing member 10, so Stop walking).

さらに、所定の養生期間が経過すると、生育基盤７からは、カバープラントが生育する。生育基盤７から生育した植物は、その先端が、第１及び第２の線材８，９の上方に突出する。このため、緑化工基盤４の外側から見ると、第１及び第２の線材８，９は、植物に隠れてさらに目立たなくなる。そして、ニホンジカ等の獣類が、植物を食べようとして、第１又は第２の線材８，９等に気付かずに緑化工基盤４に侵入した場合、第１又は第２の線材８，９や、間隔保持部材１０、突起部１５が、獣類の足に引っ掛かる。このため、獣類は警戒して、緑化工基盤４への侵入を中止する。 Furthermore, when a predetermined curing period has elapsed, a cover plant grows from the growth base 7. The tip of the plant grown from the growth base 7 protrudes above the first and second wire rods 8 and 9. For this reason, when it sees from the outside of the greening construction base | substrate 4, the 1st and 2nd wire 8 and 9 hides in a plant, and becomes inconspicuous. And when beasts such as sika deer invade the revegetation base 4 without noticing the first or second wire rods 8, 9 etc., trying to eat the plant, the first or second wire rods 8, 9, The space | interval holding member 10 and the projection part 15 are hooked on the leg of a beast. For this reason, the beasts are wary and stop the intrusion into the revegetation base 4.

上記実施形態によれば、以下のような効果を得ることができる。
（１）上記実施形態では、獣類の侵入を防止するための第１及び第２の線材８，９を、法枠３の横梁３ａ（又は縦梁３ｂ）に平行に、縦梁３ｂ（又は横梁３ａ）の上面３ｇ，３ｈに沿って張設するようにした。このため、第１及び第２の線材８，９は、法枠３内の生育基盤７から離間した状態となり、獣類が緑化工基盤４に侵入した際に、獣類の足が第１及び第２の線材８，９と接触せざるを得なくなる。このため、獣類の警戒心を煽るとともに、急傾斜での不安定な行動を余儀なくされる。従って、緑化工基盤４への獣類の侵入頻度を減少させることができる。その結果、獣類により、法枠３内に生育した植物が採食される、いわゆる食害を防止することができる。また、獣類による、法枠３内に生育した植物の踏み荒らしを防止できる。さらに、獣類の侵入防止のための施工が簡単になるとともに、金網を敷設する場合等に比べてコストを削減できる。また、第１及び第２の線材８，９は、緑化工基盤４の外側から見た場合に目立たないので、金網等のネットを敷設する場合に比べて、緑化工基盤４の景観を向上させることができる。 According to the above embodiment, the following effects can be obtained.
(1) In the above embodiment, the first and second wire rods 8 and 9 for preventing the invasion of animals are parallel to the horizontal beam 3a (or vertical beam 3b) of the frame 3 and the vertical beam 3b (or horizontal beam). It was stretched along the upper surfaces 3g and 3h of 3a). For this reason, the first and second wire rods 8 and 9 are separated from the growth base 7 in the frame 3, and when the beast enters the greening base 4, the foot of the beast is the first and second legs. The wires 8 and 9 must be brought into contact with each other. For this reason, while beating the alertness of the beasts, it is forced to perform unstable behavior on a steep slope. Accordingly, it is possible to reduce the frequency of the invasion of the animals into the greening work base 4. As a result, it is possible to prevent so-called food damage, in which the plants grown in the legal framework 3 are eaten by the animals. Further, treading of plants grown in the legal framework 3 by beasts can be prevented. Furthermore, construction for preventing the invasion of beasts is simplified, and the cost can be reduced as compared with the case of laying a wire mesh. Moreover, since the 1st and 2nd wire 8 and 9 is not conspicuous when it sees from the outside of the greening base 4, it improves the landscape of the greening base 4 compared to the case where a net such as a wire net is laid. be able to.

（２）上記実施形態では、第１及び第２の線材８，９を、間隔を保持して平行に配置した。このため、獣類が第１及び第２の線材８，９を乗り越えて侵入を試みた場合等に、第１及び第２の線材８，９のいずれかが獣類の足に接触する確率が高くなり、確実に警戒心を煽ることができる。また、線材を必要最低限の２本にすることで、施工を簡単にするとともに、コストを削減することができる。 (2) In the said embodiment, the 1st and 2nd wire 8 and 9 was arrange | positioned in parallel, maintaining the space | interval. For this reason, when a beast tries to invade over the first and second wire rods 8 and 9, there is a high probability that either the first or second wire rod 8 or 9 comes into contact with the foot of the beast. , You can definitely be alert. Moreover, by using the minimum two wires, the construction can be simplified and the cost can be reduced.

（３）上記実施形態では、第１の線材８を、法枠３の横梁３ａ又は縦梁３ｂの角頂部３ｅから、水平方向において７０〜１２０ｍｍの位置に設けるようにした。このため、法枠３内に侵入する際に、獣類の足と第１の線材８とが接触しやすい。さらに、第２の線材９を、横梁３ａ又は縦梁３ｂの角頂部３ｅから水平方向に２００〜４５０ｍｍの位置に配置するようにした。このため、第１及び第２の線材８，９を乗り越えるのを困難にするとともに、第１及び第２の線材８，９の間を踏み込んだ際にも、第１又は第２の線材８，９と獣類の足とが接触するようにすることができる。 (3) In the said embodiment, the 1st wire 8 was provided in the position of 70-120 mm in the horizontal direction from the top 3e of the horizontal beam 3a of the frame 3 or the vertical beam 3b. For this reason, when invading into the legal frame 3, the leg of the animal and the first wire 8 are likely to come into contact with each other. Further, the second wire 9 is arranged at a position of 200 to 450 mm in the horizontal direction from the top 3e of the horizontal beam 3a or the vertical beam 3b. For this reason, it is difficult to get over the first and second wire rods 8 and 9, and also when the space between the first and second wire rods 8 and 9 is stepped on, the first or second wire rods 8 and 9 9 and the feet of the beast can be in contact.

（４）上記実施形態では、第１及び第２の線材８，９の間に間隔保持部材１０を設けた。このため、獣類の侵入等により外力が加えられても、第１及び第２の線材８，９が接近することがなく、獣類の侵入を防止するために予め設定された適度な間隔を保持することができる。 (4) In the above embodiment, the spacing member 10 is provided between the first and second wires 8 and 9. For this reason, even if an external force is applied due to the invasion of beasts, the first and second wire rods 8 and 9 do not approach, and an appropriate interval set in advance to prevent the invasion of beasts is maintained. be able to.

（５）上記実施形態では、第１及び第２の線材８，９は、縦梁３ｂ又は横梁３ａ上に突
起部１５を備えるようにした。このため、獣類が、縦梁３ｂ又は横梁３ａに沿って歩行したとき、足が突起部１５に引っ掛かりやすくなる。又は、突起部１５を警戒させることにより、獣類の横歩き又は縦歩きを抑制できる。従って、縦梁３ｂ又は横梁３ａに沿った歩行も防止するので、緑化工基盤４への侵入をより困難にすることができる。 (5) In the above embodiment, the first and second wire rods 8 and 9 are provided with the protrusions 15 on the vertical beam 3b or the horizontal beam 3a. For this reason, when a beast walks along the vertical beam 3b or the horizontal beam 3a, the foot is easily caught on the protrusion 15. Alternatively, the sidewalk or the vertical walk of the beast can be suppressed by alerting the protrusion 15. Therefore, since walking along the vertical beam 3b or the horizontal beam 3a is also prevented, it is possible to make it more difficult to enter the greening work base 4.

(A) The method for preventing invasion of beasts according to claim 1 or 2, wherein the wire is arranged at a position of 70 to 450 mm in a horizontal direction from a beam constituting the frame. Prevention method.

従って、この（ａ）に記載の発明によれば、線材は、梁から水平方向に７０〜４５０ｍｍの位置に設ける。このため、特に偶蹄目類が、容易に線材を跨いだり、線材の手前を踏み込んだりすることが困難になる。 Therefore, according to the invention described in (a), the wire is provided at a position of 70 to 450 mm in the horizontal direction from the beam. For this reason, it becomes difficult especially for cloven-hoofers to straddle the wire or to step in front of the wire.

（ｂ）請求項２又は（ａ）に記載の獣類の侵入防止方法において、前記各線材のうち、前記梁に最も近い線材を、前記梁から水平方向に７０〜１２０ｍｍの位置に配置することを特徴とする獣類の侵入防止方法。 (B) In the method for preventing invasion of beasts according to claim 2 or (a), among the wires, the wire closest to the beam is disposed at a position of 70 to 120 mm in the horizontal direction from the beam. A method for preventing the invasion of beasts.

従って、この（ｂ）に記載の発明によれば、梁に近い線材は、梁から水平方向に７０〜１２０ｍｍの位置に設ける。このため、侵入を試みた獣類の足が、その線材に接触しやすくなる。従って、獣類による緑化構造物への侵入が困難になる。 Therefore, according to the invention described in (b), the wire rod close to the beam is provided at a position of 70 to 120 mm in the horizontal direction from the beam. For this reason, the leg of the animal which tried to invade becomes easy to contact the wire. Therefore, it becomes difficult for the animals to enter the greening structure.

（ｃ）（ｂ）に記載の獣類の侵入防止方法において、前記梁に最も近い前記線材に隣合う線材を、前記梁から、水平方向に２００〜４５０ｍｍの位置に配置することを特徴とする獣類の侵入防止方法。 (C) The method for preventing invasion of beasts according to (b), wherein a wire adjacent to the wire closest to the beam is disposed at a position of 200 to 450 mm in the horizontal direction from the beam. Intrusion prevention method.

従って、この（ｃ）に記載の発明によれば、梁に最も近い線材に隣合った線材は、梁から水平方向に２００〜４５０ｍｍの位置に設ける。このため、獣類が、梁に最も近い線材を乗り越えても、その次の線材が近くにあるので、獣類の足に、線材を接触させることができる。 Therefore, according to the invention described in (c), the wire adjacent to the wire closest to the beam is provided at a position of 200 to 450 mm in the horizontal direction from the beam. For this reason, even if the animal gets over the wire closest to the beam, the next wire is close to the animal, so that the wire can be brought into contact with the leg of the animal.
