Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening method on a hard slope.

[0002]

2. Description of the Related Art Conventionally, cutting slopes have been subjected to a greening method from the viewpoint of protection of the slopes and landscape. When the ground of the slope is soft, the artificially planted plant is likely to take root on the original ground, and the vegetation material is easily settled. On the other hand, when the concrete spraying slope or the ground is hard slope, even if the vegetation material is sprayed, the roots cannot be extended to the inside of the slope, so that the vegetation material tends to slide down and greening is difficult.

[0003] However, there has been a demand for greening hard slopes from the viewpoint of landscape. Therefore, a hard slope has been greened by directly spraying the vegetation material onto the slope or forming a concrete slope or the like and then filling the slope with the vegetation material.

[0004]

The above-described conventional slope greening method on a hard slope has the following problems. <A> Just spraying vegetation directly onto a hard slope
The vegetation material is easy to peel off from the slope, and plants are difficult to grow. <B> When installing a legal frame, it is necessary to perform temporary fixing or fixing with an anchor as a series of operations with the legal frame installation in order to prevent the legal frame from shifting on a hard slope. Therefore, work efficiency is poor. <C> When the legal frame is fixed to the slope from the beginning by temporary fixing or the like, it is necessary to accurately arrange the legal frame from the beginning. <D> When forming a concrete method frame or the like, it is necessary to separately perform a concrete method frame work.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned conventional problems, and to provide a slope revegetation method on a hard slope which has good fixation of vegetation material and excellent workability. With the goal.

[0006]

Means for Solving the Problems To achieve the above object, a method for revegetating a slope on a hard slope according to the present invention includes a stepping method for a concrete or mortar spraying slope or a slope on a hard ground. After temporarily placing the sill on the slope, the legged sill is fixed to the slope by placing an anchor, and the vegetation material is filled around the legged sill. is there.

[0007]

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

<A> Prerequisites for applying the present invention The slope revegetation method on a hard slope of the present invention is a method that is difficult to revegetate, such as a concrete or mortar sprayed slope or a hard ground slope. Apply when greening the surface.

<B> Leg frame The leg frame has holes such as a wire mesh through which vegetation material can pass, and the weight per unit is light enough to be carried by human power and has flexibility. As a material of the legal frame, a wire mesh, steel, plastic, or the like can be used. As the planar shape of the normal frame, a triangle, a cross-girder, a line, and the like can be used in addition to a circle (see FIG. 3) and a square (see FIG. 4). Since the law frame has flexibility, it can be installed in close contact with a slope having irregularities.

<C> Legged Leg Frame The legged legal frame 1 installed in the present invention has a leg 11 formed by projecting a part of the side of the above-mentioned legal frame that contacts the slope. The legs 11 are, for example, protruding vertical wire rods of a legal frame made of wire mesh. FIG. 1 shows a sectional view of an embodiment of a legged legal frame. Since the leg 11 protrudes from the lower end of the slope, only the leg 11 comes into contact with the slope. The tips of the legs 11 can be sharp (see FIG. 2) or flat.

<D> Anchor The anchor 3 for fixing the legged frame 1 is formed by bending the upper end of a reinforcing bar, a round steel bar or the like. The anchor 3 is cast on the slope, the bent portion is hooked on the slope, and the legged frame 1 is fixed to the slope. Therefore, even after the vegetation material is filled, the legged frame 1 does not move due to the weight of the vegetation material.

<E> Vegetation material Vegetation material 4 is composed of soil, seeds, fertilizer, curing agent, adhesive and water. The vegetation material 4 includes materials necessary for germination and growth of plants.

The construction method of the present invention will be described below with reference to the drawings.

<A> Installation of a legged frame A legged frame 1 is placed on a concrete or mortar sprayed slope or a slope with hard ground. FIG. 2 shows an enlarged view around the leg 11 of the legged frame. If the surface of the slope is hard and rough, the tip of the leg 11 at the lower end of the legged frame is hooked on the surface of the slope, and the legged frame 1 can be formed without temporary fixing or anchoring. Do not move. Therefore, the legged frame 1 can be installed with a small amount of labor. In addition, since the temporary frame 1 with legs is not temporarily fixed from the beginning, the installation position of the legal frame 1 with legs can be corrected, and the legal frame 1 with legs can be arranged in a balanced manner on the entire slope. it can.

<B> Anchor placement After temporarily placing the legged frame 1 on the slope, the anchor 3 is placed. An anchor can be placed immediately after the legged legal frame 1 is temporarily placed, or an anchor can be placed after arranging a plurality of legged legal frames 1.

<C> Vegetation material filling After the anchor 3 is cast and the legged frame 1 is fixed to the slope, the vegetation material is filled. FIG. 4 shows an embodiment of the spraying operation. The filling of the vegetation material is performed by a spraying operation using the spraying machine 5 or the like.

[0017]

[Effects of the present invention] Since the slope greening method according to the present invention is as described above, the following effects can be obtained. <B> There is no need to perform temporary fixing or anchoring when installing the legal framework. For this reason, the work of installing the legal frame and the work of placing the anchor can be performed separately, and each work can be performed efficiently. <B> Do not completely fix the legal frame when installing the legal frame. For this reason, the position can be easily corrected after the setting of the slope, and the slope can be set on the slope in a well-balanced manner. <C> The vegetation material can be settled on a slope that is sprayed with concrete or mortar or a slope with hard ground. <D> There is no need to create a separate concrete method frame or the like to support the vegetation material.
