Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope structure for vegetation by arranging a vegetation base material on the slope.

[0002]

2. Description of the Related Art Conventionally, a method of spraying a vegetation base material on the slope and a method of arranging the vegetation base material within a legal frame a have been carried out as a method of greening the slope. What is vegetation base material?
Organic or inorganic base materials such as bark compost, peat moss, sand, soil, fertilizer and other materials necessary for plant growth. These materials and binders such as asphalt emulsion,
The seeds and water were mixed and sprayed onto the slopes with a mortar spraying gun, etc. to create green slopes. Here, the soil can also be used as a vegetation base material. In the greening b used together with the legal frame a, the vegetation base material is supported by the legal frame a (see FIG. 6). When the vegetation base material is sprayed on the slope without using the frame a, etc., the vegetation base material is sprayed after covering the slope with a wire mesh or the like. This wire mesh is arranged inside the vegetation base material and serves as a holding material for the vegetation base material.

[0003]

The above-described conventional slope structure has the following problems. <B> As the slope of the slope becomes steeper, the water supply to the vegetation base material is worse, and it is generally said that it is difficult to green the entire surface on the slope that is steeper than 1: 0.5. <B> When greening rock slopes and slopes with mortar, water is rarely supplied from the ground to the vegetation base material. For this reason, revegetation is difficult unless surface water flowing on the surface of the slope is used effectively. <C> In the method of spraying the vegetation base material on the wire mesh,
When the wire mesh and the slope are in close contact with each other, the function of the wire mesh as a holding material deteriorates. <D> In the revegetation that also uses the legal framework, it is necessary to construct the legal framework separately. In addition, when using a mortar or concrete method frame, the artificial mortar surface is exposed on the method surface, resulting in poor scenery and difficult greening. <E> As a vegetation base material, it is often the case that seeds of herbs that germinate and grow early are used by mixing a fast-acting fertilizer. For this reason, the slope will be green for a year or two after carrying out the revegetation work.
There are also slopes where plants do not settle and are not continuously greened.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a sloped structure capable of storing water inside a vegetation base material. In particular, it is an object to provide a slope structure in which surface water can be effectively used. Moreover, it aims at providing the slope structure which can improve the fixing property to the slope of a vegetation base material. Furthermore, it aims at providing the structure of the slope which can green the slope continuously. The present invention achieves at least one of these objectives.

[0005]

In order to achieve the above-mentioned object, the structure of the slope of the present invention is such that the longitudinal direction of the half-divided bamboo material is oriented in the transverse direction of the slope, and A plurality of half-divided bamboo materials are arranged on the slope at intervals in the plane direction, and the half-divided bamboo material and the slope are covered with a vegetation base material.
Here, the half-divided bamboo material may be arranged continuously in the transverse direction or intermittently. Further, it is preferable that the half-divided bamboo material is arranged so that the half-divided surface is substantially orthogonal to the slope and the half-divided surface is the upper surface. By arranging in this way, the surface water flowing down inside the vegetation base material can be effectively stored.
In addition, the function of the half-divided bamboo material as a holding material for the vegetation base material is also improved.

Further, in the above-mentioned slope structure, one end of the half-split bamboo material can be arranged above the slope than the other end. That is, the half-divided bamboo material can be arranged diagonally. By doing so, surface water can be dispersed laterally.

Further, a slow-acting fertilizer or a water retaining material can be installed in the recess of the half-split bamboo material. If a slow-acting fertilizer is installed, the effect of the fertilizer can be maintained for a long time, and if a water retention material is installed, the water retention effect can be improved.

Further, in order to effectively utilize the surface water flowing down the surface of the vegetation base material, the surface water guiding material capable of retaining a predetermined shape in the above-mentioned slope structure, one end of which is It is possible to dispose a surface water guiding material that projects from the surface of the vegetation base material in a direction that blocks the surface water that flows down and has the other end located in the recess of the half-split bamboo material. By doing so, even when the surface water flowing inside the vegetation base material is small, the surface water can be taken in and stored inside the vegetation base material.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

<A> Structure of slope The structure of the slope to which the present invention is applied is one in which the vegetation base material 31 is arranged on the slope 2 to perform revegetation. In particular, slopes with steep slopes (1: 0.5-0.3), rock slopes,
It is most suitable for slopes where it is difficult to supply water from the ground, such as slopes where mortar is sprayed. Inside the vegetation base material 31, the wire mesh 5 and the like are arranged as necessary. Further, a sand base material or the like is interposed between the vegetation base material 31 and the slope 2 as required. In the present invention, the half-split bamboo material 1 described later is arranged inside the vegetation base material 31.

<B> Half-divided bamboo material The half-divided bamboo material 1 is a material obtained by dividing a tubular bamboo material into halves so that the cross section has a half-moon shape. Bamboo is inexpensive and easily available. Further, since the material is resistant to corrosion, the effect of installation can be maintained for a long time. In the present invention, the half-divided bamboo material 1 is provided with three functions of a water retaining material, a vegetation base retaining material and a spacer.

Half-divided bamboo material 1 in which the bamboo material is divided into openings
The half-divided bamboo material 1 can be used as a water retaining material by installing the half-divided surface 12 facing upward. That is, the surface water 4 flowing down inside the vegetation base material 31 is dammed by the half-split bamboo material 1, and the surface water 4 is stored in the concave portion sandwiched between the nodes 11 of the half-split bamboo material 1, thereby exerting a water retaining function. .

By arranging the half-split surface 12 of the half-split bamboo material 1 so as to be substantially orthogonal to the slope 2, the half-split bamboo material 1 is vegetation base material 3
1 can be used as a holding material (see FIG. 1). That is, by arranging the half-divided bamboo material 1 so as to resist the exfoliation of the vegetation base material 31, the vegetation base material 31 can be effectively fixed on the slope. The half-divided bamboo materials 1 are arranged at intervals in the slope direction like a horizontal frame of a slope frame work. It is also possible to cut into a predetermined length and discontinuously arrange in the lateral direction.

If the half-divided bamboo material 1 is installed on the slope 2 before installing the wire net 5 such as lath net, the half-divided bamboo material 1 plays a role of a spacer for keeping the distance between the wire net 5 and the slope 2. . By securing a gap between the wire net 5 and the slope 2, the function of the wire net 5 as a holding material for the vegetation base material 1 can be improved.

<C> Slow-acting fertilizer The slow-acting fertilizer 32 is a fertilizer that starts to be effective as a fertilizer. The slow-acting fertilizer 32 is suitable for continuously growing plants, because the slow-acting fertilizer 32 can exhibit its effect as a fertilizer for a long time because of its late onset. For example, bone meal, manure, oil dregs, etc. can be used as the delayed-release fertilizer 32. If the slow-acting fertilizer 32 is installed in the recess of the half-split bamboo material 1 (see Fig. 4), the quick-acting fertilizer contained in the vegetation base material 31 will be consumed for the initial greening, and the effect of the fast-acting fertilizer will decrease. When the effect of the slow-acting fertilizer 32 appears around the time,
The greening of the slope can be sustained.

<D> Water retaining material By installing the water retaining material in the concave portion of the half-divided bamboo material 1, the storage effect of the half-divided bamboo material 1 can be improved. As the water retention material, solid materials such as peat moss and coconut husks, and porous materials such as pumice can be used. Further, non-woven fabrics or woven fabrics made of fibers such as natural coconut fibers, absorbent polymer materials such as emulsion-based water-absorbent polymers, and paper drain materials can be used.

<E> Surface Water Inducing Material (FIG. 5) The surface water inducing material 7 is a member for guiding the surface water 41 flowing on the surface of the vegetation base material 31 to the concave portion of the half-split bamboo material 1. Therefore, the surface water inducer 7 is effectively treated with the surface water 41.
It is preferable to use a plate-shaped material having a predetermined width and length so that the surface water 41 is guided to the inside of the vegetation base material 31 by blocking it and the vegetation base material 31 is not divided. As the surface water guiding material 7, either a water absorbing material having a water absorbing ability or a water retaining ability or a water shielding material capable of blocking surface water can be used. As the water absorbent material, for example, a non-woven fabric or a woven fabric made of a fiber such as a natural palm fiber, an absorbent polymer material such as an emulsion water absorbent polymer, a paper drain material and the like can be used. Further, as the water-blocking material, a wooden board, a steel plate, a rubber plate, a vinyl sheet, a plate material or a sheet material made of a recycled material can be used.

Since the surface water guiding material 7 is a member that projects from the surface of the vegetation base material 31 to block surface water, it must maintain a predetermined shape. For this reason, when the material used as the surface water guiding material 7 is a sheet material, an elastic material, or a material having low rigidity, for example, a core material is put at both ends or inside so that a predetermined shape can be maintained.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

<A> Slope shaping The present invention can be applied to all slopes 2. First, so that the vegetation base material 31 can be sprayed,
The slope 2 is shaped as necessary. When the surface of the slope 2 is sprayed with mortar 21 or the like, holes 22 having a diameter of about 40 mm are provided at predetermined intervals. The holes 22 not only facilitate the placement of the anchor pins 6, but also enable the supply of water from the ground to the vegetation base material 31. In addition, it is possible to have a sloped structure in which the roots of plants easily extend to the ground.

<B> Installation of half-divided bamboo material The half-divided bamboo material 1 is arranged so as to cross the slope 2. Also,
A plurality of half-divided bamboo materials 1 are arranged on the slope with an interval in the slope direction. The half-split bamboo material 1 is, for example, an anchor pin 6 and a slope 2
(See Fig. 1). The half-divided bamboo material 1 is formed to have a predetermined length and is intermittently arranged, for example, in the lateral direction. They can also be arranged in a staggered pattern along with the slope direction (see Fig. 3). With such an arrangement, it is possible to prevent the surface water 4 from being stored only in the upper part of the slope.

The half-divided bamboo material 1 can be installed diagonally. That is, one end of the half-split bamboo material 1 is arranged above the other end of the slope (see FIG. 2). With this arrangement, the surface water 4 that has flowed above the half-split bamboo material 1 can be laterally guided by causing the knot 11 to overflow. As a result, water can be supplied to the vegetation base material 31 in a wide range even if the path of the surface water 4 is limited to a part such as a water path.

Note that the half-divided bamboo material 1 can be continuously arranged in the lateral direction like a lateral frame of a legal frame. In this case, the surface water 4 flowing down from above is the half-divided bamboo material 1
Overflow and flow downward. Further, of the rainfall that falls between the half-split bamboo materials 1 arranged above and below, the water that has permeated the vegetation base material 1 is also stored in the lower half-split bamboo material 1.

<C> Arrangement of wire mesh After the half-divided bamboo material 1 is installed, the slope 2 is covered with a wire mesh 5 if necessary. The half-divided bamboo material 1 arranged between the wire net 5 and the slope 2 serves as a spacer, so that a gap can be secured between the wire net 5 and the slope 2. When the anchor pin that stops the wire mesh 5 and the anchor pin that fixes the half-divided bamboo material 1 are used in common, the half-divided bamboo material 1 may be temporarily fixed or may be laid down and laid up and then raised. Secure with anchor pin 6 at the same time.

<D> Spraying the vegetation base material 31 The vegetation base material 31 is sprayed on the slope 2. In addition, slope 2
It is also possible to select the layout of the soil depending on the slope of the. The slope 2, the half-divided bamboo material 1 and the wire mesh 5 are covered with the vegetation base material 31, and the creation of the slope is completed.

<E> Path of surface water The surface water 4 flowing down the vegetation base material 31 is blocked by the half-split bamboo material 1 protruding from the slope 2. And
The dammed surface water 4 is stored in the concave portion of the half-split bamboo material 1. Here, the surface water 4 overflowing from the concave part of the half-split bamboo material 1
Flows out below or laterally of the slope. Therefore, when the surface water 4 is small, it is possible to reliably store the water, and when the surface water 4 is concentrated in a specific place, the water can be dispersed in a wide range.

<F> Surface water path Surface water 41 flowing down the surface of the vegetation base material 31 is blocked by the protruding surface water guiding material 7. Then, the dammed surface water 41 is guided to the concave portion of the half-split bamboo material 1 along the surface water guiding material 7. Here, when the surface water-inducing material 7 is a water-absorbing material, a part or most of the surface water 41 is absorbed by the surface-water-inducing material 7 and is stored in the concave portion of the half-split bamboo material 1 through the inside. It

<G> Arrangement of slow-acting fertilizer or water-retaining material In the recess of the half-split bamboo material 1, slow-acting fertilizer 32, water-retaining material, or both can be arranged (see FIG. 4). By setting the slow-acting fertilizer 32 in the half-split bamboo material 1 in advance, the slow-acting fertilizer 32 can be installed on the slope 2 at the same time when the half-split bamboo material 1 is installed.
Can be installed in Therefore, efficient construction can be performed. Moreover, since the slow-acting fertilizer 32 is arranged in the deep part of the vegetation base material 31, the effect of the fertilizer can be gradually exhibited.

[0029]

Since the sloped structure of the present invention is as described above, the following effects can be obtained. <B> Surface water that flows down inside the vegetation base material is stored in the recess of the half-split bamboo material. Therefore, it is possible to store the water necessary for the growth of the plant even inside the vegetation base material on the slope where the water is hardly supplied from the natural ground. <B> Surface water can be effectively used. Therefore, even if the slope is steep (1: 0.5 to 0.3), rock slope, slope with mortar, etc., it is difficult to supply water from the ground. Can be satisfactorily greened. <C> Half-divided bamboo material is arranged in a strip shape protruding from the slope.
Therefore, it exerts an effect as a holding material for the vegetation base material. It also serves as a spacer (spacer) between the slope and the wire mesh when the wire mesh is arranged. As a result, the fixability of the vegetation base material on the slope is improved. <D> When the slow-acting fertilizer is placed in the recess of the half-split bamboo material, the effect of the fertilizer can be continuously exerted.
