DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for promoting plant growth on a slope to promote greening, and to fix a slope with a vegetation base agent in a greening construction for protecting the slope. The present invention relates to a slope greening structure and a slope greening method.

[0002]

2. Description of the Related Art Conventionally, as one means for greening a slope, a step-like greening structure in which a welded wire mesh frame is bent in a step-like manner is attached to the slope using an anchor or the like, and a vegetation base is attached to this. The technique of greening by filling wood is known as a step vegetation method.

In order to form a stable vegetation base on the slope by a simple and easy operation, three welded wire meshes are assembled in an inverted triangular shape and attached to the slope as a single greening structure. Technology for filling and greening the base material
It is presented in Japanese Patent Application Laid-Open No. 9-235734.

[0004]

However, in the conventional step vegetation method described above, a self-supporting, but rigid, step-like greening structure, which is formed by bending a plurality of steps in advance, is used as an anchor. It is attached to the slope using a steel plate and concrete nails.

For this reason, there are various irregularities on the surface,
It is difficult to attach an inflexible step-like greening structure to the slope where the slope changes, and it has to be folded or grounded to fix along the slope, which is not easy.

[0006] Further, the conventional step-like greening structure comprises:
Since it is manufactured integrally including a plurality of stairs and is difficult to transport and store, it must be assembled individually on site, which requires a lot of construction time and high manufacturing costs.

Further, the greening structure disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 9-235734 is a method in which three wire mesh frames are folded into an inverted triangle to form one unit. Since a body is required and unnecessary wire mesh on the side of the slope is increased, the cost is high both in terms of product and labor for construction.

The present invention eliminates such drawbacks, can be manufactured at low cost, is convenient to store and transport, and has a step-shaped slope edge that is easy and reliable to attach to the slope. To provide a structured structure.

[0009]

In order to solve the above-mentioned problems, a slope greening structure according to the present invention comprises a plurality of tread metal mesh frames and a riser metal mesh frame each having a rectangular shape alternately and unfolded. Are foldably connected to each other so as to take a step shape when placed on a slope in a state, and a retaining sheet is attached to the riser surface wire mesh frame so as to form a pocket, and the riser surface is A heat insulating sheet is hung on the inner surface of the wire mesh frame. Then, the lower connecting portions of the tread mesh screen frame and the riser mesh screen frame of the slope greening structure are sequentially fixed to the slope to be fixed in a step-like manner, and then,
A vegetation base material for growing a plant is filled in the soil retaining sheet attached to the riser mesh frame.

Since the stepped wire mesh frame and the riser wire mesh frame are formed in a step-like manner, a wire mesh frame on the slope side such as a slope structure composed of three wire mesh frames is not required, and the product is manufactured. In addition, cost can be reduced in terms of construction.

Since the tread mesh frame and the riser mesh frame are foldable, they can be shipped from the factory in a folded state, and there is no need to assemble them individually on site. The manufacturing cost is low, and it is convenient for storage and transportation.

[0012] In particular, since the tread mesh frame and the riser mesh frame are sequentially connected so as to be foldable so as to exhibit a step-like shape, when mounting at the site,
Even if there are various irregularities on the surface of the installation slope or the slope changes, it can be easily fixed along the slope, and the tread mesh frame and the riser mesh frame are tied together. When they are connected in a shape, they are advantageous in terms of manufacturing process and cost.

[0013] Further, since the retaining sheet is attached to the riser screen metal frame so as to form a pocket, the inserted vegetation base material is securely held, and the heat insulation sheet is provided on the inner surface of the riser screen metal mesh frame. Is suspended, so that vegetation can be protected from freezing in winter, for example.

Further, when the upper end of the riser mesh screen is projected from the tread mesh frame by a predetermined length, the vegetation base material put into the retaining sheet attached to the tread mesh frame may be removed. If a large number of fallen leaves and the like accumulate on the surface and humus to serve as fertilizer, and the lower end of the riser mesh screen is projected from the tread mesh frame by a predetermined length, the tread mesh frame may be used. The roots of the plants that grew on the vegetation base material entered into the soil sheet formed at the bottom easily entered the vegetation base material entered into the soil sheet formed on the lower tread wire mesh frame, and became more stable. Form a slope. Furthermore, when the end on the side of the slope of the tread metal mesh frame is protruded from the riser mesh wire frame by a predetermined length, it is put into the earth retaining sheet formed on the tread metal mesh frame above the stairs. The roots of the plants grown on the vegetation base material easily enter the vegetation base material placed on the retaining sheet formed on the lower tread wire mesh frame, and not only constitute an extremely stable slope, but also Even if a load is applied to the recessed screen wire frame, no horizontal tensile force is applied to the tread wire frame, and the slope greening structure is installed on the slope in a stable state.

[0015] In addition, the mesh of the wire mesh of the tread
By making the mesh of the wire mesh of the riser surface wire mesh frame finer, it is possible to easily put the vegetation base material after it is attached to the slope, and to effectively prevent the thrown-out vegetation base material from flowing out.

The slope greening structure of the present invention is
When mounting on a slope, a wire mesh is stretched on the slope in advance, and the lower connecting portion between the tread mesh frame and the riser mesh frame is connected and fixed to the wire mesh with a fastener such as a C-ring. In this case, installation is easier, and reinforcing material such as reinforcing steel is laid at the joint between the tread mesh frame and the riser mesh frame, which are the fixing parts to the slope, and this is fixed to the slope with the anchor. In the case where it is reinforced by spraying a hardening material such as concrete after fixing it to the base, it can be attached more firmly.

The slope 7 constructed by using the slope structure as described above grows seeds and seedlings sowed in the vegetation base material 10 filled in the soil retaining sheet 5 to grow stems and As the trunk, the leaves, etc. grow, fallen leaves accumulate and the slope structure 1 gradually becomes invisible from the outside, greening is promoted, and a natural scenery can be obtained (not shown).

Further, the roots of the plants growing on the vegetation base material 10 penetrate through the soil retaining sheet 5 and the heat insulating sheet 6 and are integrated with the slope to keep the slope 7 green and prevent the slope 7 from collapsing. .

FIGS. 3 and 4 show different embodiments of the slope greening method using the slope greening structure 1 according to the present invention. The slope greening of the embodiment shown in FIG. After the slope greening structure 1 is attached to the slope 7 in the same manner as the method, as shown in FIG. Reinforcing material 11 such as a reinforcing bar is arranged along the connection with the upper edge of the sheet metal mesh frame 3,
This is fixed to the slope 7 with the anchor 12, and then, as shown in FIG. 4, a hardening material 13 such as concrete is sprayed to reinforce it. Therefore, the slope structure 1 can be attached more firmly. In this embodiment, the reinforcing member 11 such as a reinforcing bar is connected to the lower edge of the tread mesh frame 2 and the upper edge of the riser mesh frame 3 which are fixed portions to the slope 7. The reinforcing members 11 may be arranged in a direction intersecting the connecting portion. In particular, by reinforcing the reinforcing members 11 in both directions to cross each other, the reinforcing members 11 are arranged in a normal frame shape. It can be further reinforced (not shown).

As shown in the drawing, the roots 17 of the plants 16 grown on the vegetation base material 10 placed in the soil retaining sheet 5 attached to the wire mesh frame 2 are located not only inside the slope 7 but also below the tread. Since it enters into the vegetation base material 10 put in the retaining sheet 5 attached to the wire netting frame 2 and is rooted, a more stable slope 7 can be formed.

FIG. 9 is a view in which the upper end and the lower end of the riser mesh screen frame 3 constituting the slope greening structure 1 are projected from the tread mesh screen frame 2 by a predetermined length. 7 has the advantages of the embodiment shown in FIG.

FIG. 10 shows a form of the samurai history in the case where the end of the step surface side of the wire mesh frame 2 on the side of the slope 7 is projected from the wire mesh frame 3 by a predetermined length. In this case, as shown in FIG. 11, the roots 16 of the plants 15 grown on the vegetation base material 10 placed in the retaining sheet 5 formed in the upper tread metal mesh frame 2 are easily moved to the lower tread. Vegetation base material 1 put into earth retaining sheet 5 formed in wire mesh frame 2
0, and not only constitutes a very stable slope 7, but even if a load is applied to the riser mesh 3, no tensile force is applied to the tread mesh 2 in the horizontal direction.
The slope greening structure is installed on the slope in a stable state.

In each of the above-described embodiments, the tread mesh screen frame 2 and the riser mesh screen frame 3 are used by being developed in a substantially right angle state, for example, as shown in FIG. As described above, in the case of constructing the slope 7 having a gentle slope, the tread mesh screen frame 2 and the riser mesh screen frame 3 may be used by being developed at a wide angle, and as shown in FIG.

In this case, the tread mesh screen frame 2 and the riser mesh screen frame 3 may be deployed at an acute angle.

As described above, the unfolding angle between the tread mesh frame 2 and the riser mesh frame 3 is adjusted according to the slope to be constructed, so that it can be used regardless of the slope of the slope. In this case, a slope greening structure that does not restrict the development angle between the tread surface wire mesh frame 2 and the riser wire mesh frame 3 is used, and the slope is formed at a desired deployment angle according to the slope angle of the slope at the time of construction. It is conceivable to prepare a plurality of types with different deployment angles in advance, and to select and use the one corresponding to the slope from among them. Since it is not necessary to prepare a plurality of different types, there are advantages such as being economically superior and being able to cope with a case where the slope of the slope changes continuously and greatly. The latter is excellent in that it is easy to construct because the tread mesh screen frame 2 and the riser mesh screen frame 3 exhibit a desired angle only by being developed at the time of construction.

The cost is low, it is convenient for storage and transportation, and in particular, the configuration is such that the tread mesh frame and the riser mesh frame are sequentially connected so as to be foldable so as to exhibit a step shape at the vertical edge. Because of this, when mounting on site, even if there are various irregularities on the surface of the mounting slope or the gradient changes, it can be easily fixed along the slope.

Further, since the earth retaining sheet is attached to the upper end edge of the riser metal screen frame so as to form a pocket, the inserted vegetation base material is securely held, and the inner surface of the riser metal screen frame is secured. Since the heat insulation sheet is hung on the ground, it is possible to protect the vegetation from freezing in winter, etc., and to coarsen the mesh of the tread wire mesh frame, By making it finer, it is possible to easily feed the vegetation base material after the vegetation base material is attached to the slope, and to effectively prevent the thrown-out vegetation base material from flowing out.

Further, when the slope greening structure of the present invention is mounted on the slope, a wire mesh is previously stretched on the slope, and the lower edge of the tread wire mesh frame and the riser mesh are meshed. When the connection with the upper edge of the frame is connected and fixed with a fastener such as a C-ring, the attachment is easier, and the lower edge of the tread metal mesh frame, which is the fixing portion to the slope, is kicked in. Reinforcing material such as reinforcing steel is arranged at the connection with the upper edge of the mesh screen frame, fixed to the slope with an anchor, and then stiffened by spraying hardened material such as concrete, if it is reinforced, it will be attached more firmly be able to.
