DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation net for vegetation and a vegetation base for use in, for example, a slope revegetation method.

[0002]

2. Description of the Related Art Hitherto, a greening method has been applied to a slope on a hillside formed for road construction, land development, or the like in order to protect the landscape and maintain the landscape. As one of the greening methods, a bag storage section is formed in a greening vegetation net consisting of warp and weft, and organic compost, chemical fertilizer, vegetable fiber, water retention agent, soil improvement material, etc. A storage bag for a vegetation material that directly or indirectly contributes to the growth of a plant containing the vegetation is stored, and a sheet supporting plant seeds is provided on one side of the vegetation net. There is a construction method in which a vegetation substrate is laid on a slope surface as a substrate.

In addition to the above, a vegetation base containing a vegetation material storage bag stored in a vegetation net bag storage portion is used as a vegetation base for greening, and the vegetation base is laid on a slope. There is also a greening method of spraying a thick base material mixed with, or an organic soil containing plant seeds.

In the conventional vegetation substrate for greening used in these greening methods, a double net is used to hold the bag storage portion on the vegetation net. Or a single (single) net as shown in Japanese Patent Application Laid-Open No. 6-185061, and a part of the warp is provided on one side of the net. The bag storage portion is formed so as to be parallel to the weft so as to dive.

[0005]

However, in the above-mentioned means, since a double net is used, a large number of yarns are required as a material for manufacturing the net, and the manufacturing process is complicated. There is a problem that the manufacturing cost increases.

On the other hand, in the above-mentioned means, although there is no problem as in the above-mentioned means, since the bag for storing the vegetation material only sunk the warp of the net, the holding of the vegetation material storage bag in the vegetation net is not necessarily reliable. But not
There is also a problem that it is difficult to store the vegetation material storage bag in the bag storage section.

[0007] Further, although it is common to the above, depending on the conditions of the slope, there is a demand to selectively and densely install the vegetation material storage bag at an arbitrary position on the slope. In the means of (1), since the bag storage portions are sparsely formed at intervals in the warp direction of the vegetation net, there is also a problem that the installation position of the vegetation material storage bag is limited to sparse.

[0008] The present invention has been made in consideration of the above-mentioned matter, and an object of the present invention is to easily and reliably hold a vegetation material storage bag in a bag storage portion. It is also possible to easily install the vegetation material storage bag at any position on the slope,
It is an object of the present invention to provide a greening vegetation net having a simple configuration and a low cost, and a greening vegetation substrate using the net.

[0009]

In other words, the vegetation net for greening according to the present invention is used for forming a bag storage portion for storing a vegetation material storage bag in a single net composed of a warp and a weft. In a single net, weaving a warp and a weft different from those for net weaving at appropriate intervals in the weft direction and the warp direction so as to form a double structure with the single net. The bag accommodating portion is formed by being dispersed on one side of the single net by the portion and the single net portion.

[0010] As a distribution form of the bag storage section, for example, a form in which the corners of the bag storage section are brought close to each other to disperse the bag storage section in a checkered pattern can be selected.

One of the vegetation bases for greening according to the present invention comprises a vegetation material storage bag stored in the bag storage portion of the vegetation net constructed as described above. It is suitable for use in a greening method for spraying an organic soil including a layer base material and plant seeds. Another greening vegetation base according to the present invention is a bag storage part of a vegetation net also configured as described above. The vegetation material is stored in a bag, while a sheet supporting plant seeds is provided on one side of the vegetation net, which is suitable for use in a greening method in which only a vegetation base is laid on a slope. It is something.

In the vegetation net having the above-described structure, the net material is required for the weft thread for forming the bag storage portion. The manufacturing cost of the vegetation material storage bag is low, and the vegetation material storage bag is easily stored in the bag storage portion, and the storage bag is securely held.

[0013] Most of all, since the bag storage portion is formed on one side of the single net in a checkered pattern or the like, the storage bag for the vegetation material is selected at an arbitrary position in the vegetation net. Can be accommodated.

According to this, it is possible to obtain a vegetation base on which the storage bags for the vegetation material can be selectively and sparsely installed according to the conditions of the slope, as desired. By using the above vegetation net,
A vegetation base for greening that can reliably hold the vegetation material storage bag can be obtained at low cost.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a vegetation base 1 for greening, and FIG. 2 shows a main part of the vegetation base 1.
The vegetation substrate 1 for greening comprises a sheet 3 supporting a vegetation substrate 2 containing plant seeds provided on one side of a vegetation net 4, and a vegetation material storage bag in a bag storage portion 5 formed on the vegetation net 4. 6 is stored.

FIG. 1A shows the front side of the greening vegetation substrate 1, and FIG. 1B shows the rear side. The back surface side of the greening vegetation substrate 1 referred to here is a surface laid on the slope N as shown in FIG.

When weaving the single net 9 with the warp 7 and the weft 8, the vegetation net 4 is appropriately spaced in the weft direction and the warp direction of the single net 9 as described later. The bag storage portion 5 of the vegetation material storage bag 6 is formed. The material of the warp 7 and the weft 8 is a material having excellent corrosion resistance such as polyethylene or polypropylene, or a plant such as hemp or jute. The following materials can be suitably used in addition to conventional materials, such as those which are corroded in a relatively short period of time, such as synthetic fibers or viscose rayon.

That is, there are strong rayon, various corrosive materials subjected to preservative treatment (these materials and vegetation nets using them are disclosed in Japanese Patent Publication No. 6-99918), Blended fiber consisting of synthetic fibers and synthetic fibers, or mixed fiber rayon in which at least one of a polymer emulsion or a water-soluble polymer is internally added to a viscose solution (vegetation net using these materials and vegetation net using the same) As for Japan
No. 4, No. 4), and other materials such as fibers made of biodegradable bioplastic, which can adjust the corrosion time, can be suitably used.

The manufacturing procedure of the vegetation net 4 provided with the bag storage section 5 will be described with reference to FIGS. 3 to 5 as well.
A monofilament of about 2,000 denier is used, and the weft 8 is, for example, 300 to 30 made of polyethylene.
The vegetation net 4 is knitted by a Russell loom as follows using a tape-shaped flat yarn of about 00 denier.

That is, the size of the mesh is 15 mm × 15 m
m, weaving a vegetation net 4 having a width of about 100 cm in the weft direction. First, a chain yarn obtained by chain knitting several monofilaments is used as a warp yarn 7 for net knitting, and 65 of these yarns are spaced at 15 mm intervals. Then, the weft 8 for net weaving made of flat yarn was sequentially entangled with this,
The single net 9 is knitted and woven to a size of × 15 mm.

At the time of weaving of the single net 9, two net knitting warps 7A, 7A are specified for every two meshes at one end and for each mesh at every six meshes. , So as to form a warp group with these warps 7A, 7
A bag storage portion made of, for example, a monofilament, which is different from that for net weaving, is hooked and connected to A, and the warp yarns 7B, 7B of each warp group are connected to the bag storage portion made of, for example, a flat yarn. The first weft 8A for weaving is connected in a stitch shape.

On the other hand, as shown in FIG. 6, except for the warp group on one end side, a second weft for weaving in a bag storage section made of, for example, a flat yarn is provided on one end warp 7B in the weft direction of the remaining warp group. 8B is entangled so as to form a loop.

The above-described warp yarns 7B, 7B for weaving in the bag storage portion are hooked and connected to the warp yarns 7A, 7A for weaving the net only in a small number of meshes such as one mesh or two meshes of the single net 9. Alternatively, as shown in the drawing, the hooking connection is simply performed once, and the hooking connection is repeatedly performed every time the single net 9 is knitted and woven over a predetermined number of meshes.

Therefore, between the connecting portions of the warps 7A and 7B in the warp direction, the first net 9 is separated from the first net 9 while being separated.
The warp yarns 7B, 7B connected in a stitch shape by the weft yarns 8A exist in a belt shape.

Then, the warp yarns 7A, 7A and the warp yarns 7B, 7B
In the continuous weaving of the single net 9 while the hooks are not hooked and connected, the second weft 8B for knitting in the bag storage section in each warp group is combined with the warp 7B that has been entangled so far and the warp adjacent to one side in the weft direction. Jump connection is repeatedly performed over the end warp 7B of the group. At this time, every other warp group is specified in the weft direction,
The jump connection of only the wefts 8B of the remaining warp groups and the jump connection of only the wefts 8B of the specified warp groups are performed every time the hook connection between the warps 7A, 7A and the warps 7B, 7B is completed. Is performed alternately and repeatedly.

By taking the above-described knitting form, the warp 7B,
A first weft 8A in which meshes 7B are connected in a mesh shape, a second weft 8B in which jump connection is repeatedly performed, and a single net portion 9A opposed to the first weft 8A, at appropriate intervals in the weft direction and the warp direction, Warp 7A, 7A and warp 7
A bag storage part 5 is formed in a non-connection part with B, 7B, that is, a vegetation provided with a checkerboard-shaped bag storage part 5 whose corners are close to each other on one side of a single net 9. Net 4
Is manufactured.

In this embodiment, the second weft 8B for weaving the bag storage section is formed by connecting end warps 7B, 7B adjacent to each other.
Over, the jump connection is performed at a half-mesh pitch of the single net 9, but the jump connection is performed at a single-mesh pitch or a two-match pitch of the single net 9 so as to be sparser than this pitch. It may be.

In jump connection of the second weft 8B, as shown in FIG. 6, the second weft 8B is entangled with the warp 7B for knitting and weaving the bag storage section so as to form a loop.
Since the tight structure is formed, the vegetation net 4 is effectively prevented from being twitched, which is preferable. However, as shown in FIG. May be inserted and locked so as to be entangled with the warp 7B. In this case, the vegetation net 4 can be made flexible because a loose structure can be formed.

A sheet 3 carrying a vegetation base material 2 is provided on the back side of the vegetation net 4 having the above structure, and a vegetation material storage bag 6 is provided in a bag storage portion 5 of the vegetation net 4.
Is stored to form the vegetation substrate 1 for greening. In the vegetation substrate 1 having such a configuration, the production of the vegetation net 4 is more complicated than the means of forming the entire net into a double structure. The cost is low, and the second weft 8B for weaving the bag storage unit
The bag storage section 5 is formed simply by appropriately jump-connecting the vegetation net 4. Therefore, the vegetation net 4 having the bag storage section 5 can be easily and inexpensively manufactured. Is easily stored, and the storage bag 6 is securely held.

In addition, since the bag storage units 5 are dispersed in a checkered pattern, the bag storage units 5 can be provided as desired according to the conditions of the slope N.
Thus, the vegetation substrate 1 can be obtained in which the storage bag 6 for the vegetation material can be installed at any position on the slope N by selecting the density.

The sheet 3 provided on the vegetation net 4
It does not hinder the germination and growth of plant seeds, and it also dissolves with water, such as crepe paper, polymer film or starch film, water-soluble paper with cold gauze, soft cotton, soft nonwoven fabric, pulp nonwoven fabric, etc. Although a water-soluble material or a water-decomposable material can be selected, in this embodiment, as shown in the enlarged view of FIG.
A vegetation base material 2 made of a plant seed, a fertilizer, a soil conditioner, or the like is adhered to and held on the sheet 3 by using a water-soluble glue such as polyvinyl alcohol (PVA) using a thin cotton wrap made of cloth. And this sheet 3
Is attached to the back side of the vegetation net 4 using the same water-soluble glue as the above-mentioned water-soluble glue.

On the other hand, the vegetation material storage bag 6 is used to remove the vegetation material 10 such as fertilizer, soil conditioner, water retention agent, etc., which is necessary directly or indirectly for the growth of the plant, such that the fertilizer nutrient gradually seeps out due to rainfall or the like. Non-woven fabrics such as vinylon-based materials such as polyvinyl alcohol, polyester-based materials such as polyester, polyamide-based materials such as nylon, polyacrylonitrile-based materials such as acrylic, etc. 1 made of corrosive materials such as paper, soluble paper, biodegradable plastic film
The plant seeds are mixed into the vegetation material 10 as necessary.

At the time of greening the slope N, as shown in FIG. 8, the vegetation substrate 1 having the vegetation material storage bag 6 stored in the bag storage portion 5 of the vegetation net 4 in advance in a factory or a construction site is used. Is laid with the sheet 3 facing the side of the slope N. At this time, as described above, the vegetation net 4
Are formed in a checkered pattern, and depending on the conditions of the slope N, as shown by solid and imaginary lines in FIG.
The storage bag 6 of vegetation material is concentrated in a certain part of
In other parts, as shown by the solid line, it is possible to arbitrarily sparsely disperse the storage bags 6 of the vegetation material.

In the state in which the vegetation base 1 is laid on the side face N, the second weft 8B jump-connected to the warp 7A for knitting the bag storage section is separated from the other yarns. In addition to the fact that the weft 8B freely adjusts to the unevenness of the slope N, the bag storage section 5 formed by the weft 8B also adapts well to the slope N, and as a result, the vegetation stored in the bag storage 5 Since the material storage bag 6 is in close contact with the uneven surface of the slope N, the vegetation material storage bag 6 not only supplies a predetermined fertilizer nutrient, but also exhibits a damming effect and erosion of the ground surface of the slope N. Will surely be prevented.

In the greening vegetation substrate 1 having the above structure, the sheet 3 supporting the vegetation substrate 2 is provided on the back side of the vegetation net 4, and the sheet 3 is provided on the front side of the vegetation net 4. When laying the vegetation substrate 1 on the slope N,
A greening method in which the sheet 3 is directed to the side of the slope N may be adopted.

Instead of the greening method in which only the vegetation base 1 is laid on the slope N, as shown in FIG. 9, the vegetation material storage bag 6 stored in the bag storage portion 5 of the vegetation net 4 is used for greening. This vegetation substrate 1 is laid on the slope N, while a thick-layer substrate (or an organic soil containing plant seeds) 12 obtained by mixing the vegetation material 10 with the plant seeds.
Can also be sprayed onto the upper surface of the vegetation substrate 1 by using a
Greening of the slope N can be achieved.

At the time of greening the slope N by these construction methods, although not shown, a vegetation material storage bag different from the predetermined storage bag 6 for the vegetation material 10, for example, hindering germination and growth of vegetation. In addition, for example, grass seeds are contained in a bag made of a soluble material such as a polymer film or a starch film dissolved in water or a water-soluble paper with a cold gauze such as Bonric (manufactured by Vensei Paper Co., Ltd.). The stored vegetation material storage bag and the storage bag 6 storing the vegetation material 10 described above are stored in a checkered bag storage portion 5 alternately or at appropriate intervals, and this is used as a vegetation base for greening. 1, and a greening method may be adopted in which the vegetation base 1 is laid on the slope N.

At this time, if the two kinds of vegetation material storage bags are prepared in a short length, the short vegetation material storage bags are alternately arranged in the weft direction with respect to the checkered bag storage portion 5. Or a configuration in which either type of storage bag is sparsely or densely arranged at a predetermined position of the vegetation net 4. In particular, when such a configuration is adopted, the vegetation substrate 1 Since the structure is easy to bend in the direction and the weft direction, there is an advantage that the vegetation substrate 1 is well adapted to the uneven surface of the slope N and easily adheres.

In the above embodiment, the number of the warp yarns forming the bag storage portion 5 is two. However, as shown in FIG. 10, the number of the warp yarns 7B for weaving the bag storage portion is three or more. Alternatively, as shown in FIG. 11, the warp 7B for knitting and weaving in the bag storage section may be reduced to one.

The second weft 8B to be jump-connected
Is entangled only in one end warp 7B in the weft direction in the warp group, but the second weft 8B is also entangled in the other end warp 7B in the weft direction, as shown in FIG. It is also possible to make a jump connection between the warp groups adjacent to each other so that the two end warps 7B, 7B cross each other.

Further, when forming the bag storage section 5, every other warp group is specified in the weft direction, and the second weft 8B is jump-connected between adjacent warp groups to form a bag storage section. 5 is formed in a checkered pattern,
It is not necessary to form a checkered pattern. For example, as shown in FIG. 13A, every two warp groups are specified in the weft direction, and as shown in FIG. The form in which the bag storage unit 5 is dispersed on one side surface of the single net 9 such as, for example, specifying every other warp group at every second and jump-connecting the second wefts 8B of those warp groups. , Various selections are possible.

The warp yarns 7 constituting the vegetation net 4
Monofilaments as A and 7B, and wefts 8 and 8
Although flat yarns are used as A and 8B, the present invention is not limited to such a type, and the combination may be the reverse of the above. All of the warp yarns 7, 7A, 7B and the weft yarns 8, 8A, 8B May be a monofilament or flat yarn, and the warp yarns 7, 7A, 7B and the weft yarns 8, 8A are flat yarns, and the weft yarn 8 to be jumped
B may be a monofilament.

The warps 7, 7A, 7B may be flat yarns, and the wefts 8, 8A, 8B may be monofilaments. In this case, the weft 8B to be jumped may be either monofilaments or flat yarns.

Further, it is possible to use two wefts 8B for the weaving of the bag storage part at the same time. In this case, a combination of a monofilament and a flat yarn, or a corroding yarn and a corrosion-resistant yarn can be used. In addition, by using two or more pieces as described above, the bag storage section 5 can be made dense by one jump.

[0045]

As described above, according to the present invention,
The vegetation net can be manufactured at a low cost as compared with the means of forming the entire net in a double structure, and the vegetation net can easily store the vegetation material storage bag in the bag storage portion. The retention is also ensured.

Since the bag storage portion is formed by being dispersed on one side of the single net, the vegetation base in which the vegetation material storage bag is stored in the bag storage portion is formed according to the condition of the slope. It is possible to obtain a vegetation material storage bag which can be selectively installed at an arbitrary position on a slope, and to use the vegetation net as the vegetation base. The work for securely holding the material storage bag is easy, the handling of the vegetation substrate itself is easy, and the greening of the slope can be achieved at low cost.
