Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation base material for slopes such as hills, slopes used for greening block walls and concrete walls.

[0002]

2. Description of the Related Art Hitherto, as a means for greening such slopes, there has been a so-called spraying method.

That is, in this conventional means, first, a wire net is stretched on a slope to form a base for preventing collapse, and then a powder made of peat moss or bark compost containing plant seeds is formed on the ground. The vegetation floor is created by spraying the granules with a heavy machine.

[0004]

However, the vegetation bed formed by the above-mentioned conventional means has a drawback that it is very likely to flow out due to wind and rain, and the thickness of the vegetation bed cannot be ensured. Plants often die without rooting, and they were not necessarily the best means for greening slopes.

[0005] Further, since a series of construction work of tensioning a wire mesh on a slope or spraying powder particles with a heavy machine is extremely complicated, not only does it impose a great burden on the operator. There is also a problem that a considerable period of work is required and the construction cost increases.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and makes it possible to surely and satisfactorily green the slope and the like, and also to simplify the field work. This is a task.

[0007]

[Means for Solving the Problems] That is, the means adopted by the present invention to solve the above-mentioned problems are as follows: It has a two-layer structure with a base material main body 2 which is provided on the side and is formed into a solid state by containing organic fertilizer, and a plurality of concave portions 4 are formed on the front surface of the base material main body 2 and The base material 1 has a water-retaining property and is made of a material capable of absorbing a liquid and expanding.

Further, as in claim 4, the base material main body 2 may be externally fitted to the front surface of the base material 1 or may constitute the base material.

Therefore, when a base material characterized by the above-mentioned matters specifying the invention is used, for example, a net having a cylindrical body capable of accommodating the base material is used. That is, the net is laid on the vegetation surface B, and the base material 1 is located on the vegetation surface B side with the seeds of the plant and fertilizer stored in the concave portion 4 of the base material body 2. The material is inserted into the tubular body of the net.

When the base material absorbs water due to water discharge, rainfall, etc., the base material main body 2 is gradually softened into a so-called available state, and the growth of the seeds stored in the concave portion 4 is promoted. , The base material 1 expands and the base material main body 2
Is always pressed forward, and the base material main body 2
However, even if the skin becomes thin over time, the state of storage of the base material in the tubular body can be maintained well.

Further, since the base material 1 is provided with the water retention property, the base material main body 2 is maintained in a supplyable state for a long period of time.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a base material formed by compressing and forming a fibrous material such as coconut fiber, peat moss, and cotton having water retention into a plate shape.

Reference numeral 2 is a base material main body having a substantially L-shaped cross section, which is made by molding Masa soil, peat moss, bark compost, pearlite, etc. into a solid state, and the base material 1 is attached to the upper surface of a bottom piece 2a thereof with a space 3. On the front surface of the base material main body 2, a plurality of concave portions 4 inclined upward toward the tip side are formed in the longitudinal direction at predetermined intervals in the width direction, and in the concave portions 4, plant seeds are formed. 5 and fertilizer 6 are stored. Reference numeral 7 denotes fertilizer stored in the space 3. In addition, the base material main body 2 and the base material 1 are, for example, holes (not shown) in which a skewer (not shown) protruding from the upper surface of the bottom piece 2a of the base material main body 2 is formed in the lower surface of the base material 1. It is inserted and fixed.

The base material A according to the present embodiment has the above-mentioned structure. When the base material A is used to green a vegetation surface B such as a slope, as shown in FIG. 2, for example. A net C in which a plurality of cylindrical bodies 8 into which the base material A can be inserted is provided on the front surface of the sheet 9 at predetermined intervals is used.

First, the base material A is inserted into each tubular body 8 of the net C so that the base material main body 2 of the base material A is located on the front surface, and then the upper piece of the sheet 8 of the net C is placed. Lay on vegetation surface B with piles 10. In this case, since the base material 1 and the base material main body 2 are in a dry state, they are very lightweight, and the work to bring them to the site and insert them into the net C is very easy, and the construction period is shortened. It will greatly contribute to the reduction of construction costs.

In this way, the base material A is arranged on the entire surface of the planted surface B to be greened. After that, when the base material A receives liquid such as water discharged toward the vegetation surface B, rainwater due to rainfall, night dew, etc., the base material 1 and the base body 2 of the base material A absorb this. As a result, the base material main body 2
Is gradually softened and expanded into a salable state, and the seeds 5 housed in the concave portions 4 are in a state capable of absorbing fertilizer components from the base material main body 2, so that germination, growth and the like are promoted. . In particular, since the seeds 5 are stored in the concave portion 4 provided on the front surface of the base material main body 2, the plants are vegetated so as to cover the front surface, and the planted surface B can be greened surely and satisfactorily. Of.

On the other hand, the base material 1 absorbs the liquid and expands, and is stored in the tubular body 8 of the net C while the base material body 2 is constantly pressed toward the front side. Since the state is maintained even if the base material main body 2 becomes thin over time, it is very effective for plant vegetation.

Moreover, since the base material 1 is provided with water retention property, when the planted surface B is made of concrete or block which cannot retain water, water is not discharged for a long period of time and no rainfall occurs. Also, the base material main body 2 is maintained in a supplyable state, and plants do not die.

Further, since the base material A according to this embodiment has a very simple structure and is attached to the net C, there is an advantage that it contributes to the reduction of construction cost.

If the fertilizer 7 is not stored in the space 3 between the base material 1 and the base material main body 2 or the storage amount is set to be small, the liquid can be stored in the space 3. ,
There is an advantage that a sufficient amount of liquid can be supplied to the base material 1 and the base material main body 2. In this case, it is desirable to block the side portion of the space 3 by extending the base material body 2.

Further, as in the above embodiment, the space 3 is not necessarily provided between the base material 1 and the base material main body 2, and may be omitted.

Further, it is possible to form the bottom piece 2a of the base material main body 2 as a separate member, or to omit the bottom piece 2a and directly provide the base material main body 2a on the front surface of the base material 1.

Further, the base material A is not limited to the one in the above embodiment, and for example, as shown in FIG. 3, the base material main body 2 is formed in a substantially rod shape having a substantially semicircular cross section, and a plurality of concave shapes are formed on the front surface thereof. The base material A may be formed by providing the portion 4 and the recess 11 at the center of the back surface thereof, and fitting the plate-shaped base material 1 into the recess 11. Also in this case, the base material body 2
The seeds 5 and the fertilizer 6 of the plant are stored in the concave portion 4 of the above, and the base material 1 is arranged on the planted surface C side and inserted into the tubular body 8 of the net C, so that The same effect as will be obtained.

Further, in the above-mentioned embodiment, the base material main body 2 is composed of soil, bark compost, bentonite, etc., but may be composed of other organic fertilizers depending on the kind of vegetation plant, and its specific constituent components are It doesn't matter.

Although the base material 1 has water retention, the water retention referred to in the present invention means that not only water but also other liquids can be retained.

In the above embodiment, the net C is used to dispose the base material A on the surface B to be planted.
The arranging means is not limited to this.

In addition, the specific construction such as the size and shape of the base material A can be arbitrarily changed within the scope intended by the present invention.

[0029]

As described above, since the base material main body according to the present invention is formed in a solid state by containing the organic fertilizer,
When the base material body absorbs water discharge, rainwater, night dew, etc., it softens and expands and gradually becomes a ready state, and a plurality of concave portions for storing plant seeds and fertilizers are formed on the front surface of the base material body. Therefore, it has been possible to obtain a particular effect that the planting surface such as a slope can be surely and satisfactorily greened under the optimum conditions for germination and growth of the seed.

Further, since the base material arranged on the vegetation surface side is constructed so as to absorb liquid and expand, the state in which the base material body is constantly pressed to the front surface side is maintained, For example, when such a base material is housed in the tubular body of the net for greening, the housed state in the tubular body is maintained well even if the base material body becomes thin over time,
It also has a unique effect that is very effective for the vegetation of plants.

Further, since the base material is provided with water retention property, when the vegetation surface is made of concrete or block which cannot retain water, water is not discharged for a long period of time, and even if there is no rainfall or the like. There is an effect that the planted surface can be appropriately greened without the plants being dead.

Further, as described above, the vegetation base material according to the present invention can be easily carried in to the site or arranged on the surface to be vegetated, so that it can greatly contribute to shortening the construction period and reducing the construction cost. There is also a practical effect.
