[0002]

2. Description of the Related Art One of the construction methods for greening a mountain surface that has naturally collapsed, a thin mountain surface, and the mountain surface that has been scraped off for road construction is to install a mesh body on the slope. The reinforcing bars are installed on the top of the grid, and mortar or concrete is sprayed on the grid-like reinforcing bars to form a grid-shaped swelling body, while plant seeds such as grass are for example organic compost, chemical fertilizers, plants. There is a method of spraying a vegetation base material mixed with a functional fiber, a water retention agent, a soil conditioner and the like onto a slope in a lattice frame surrounded by the swelling body.

[0003]

According to such a slope greening method, the lattice-shaped swelling bodies prevent the vegetation base material from running away due to rainfall, and thus the greening of the slope surface is achieved. However, there is room for improvement in that the lattice-shaped swelling body, which is an artificial structure, is conspicuous even at a long distance and deteriorates the natural landscape.

Further, in the above-mentioned slope greening, it is preferable to make the slope a forest in order to achieve harmony with the surrounding landscape of the slope, permanent stabilization of the slope and restoration to the natural world. Therefore, tree planting and tree planting for transplanting tree seedlings to the slope may be carried out at the same time, but in order to make rooting of tree seedlings easier, burrowing work of hard labor is forced. Due to the fact that the digging work and the work of accommodating the vegetation base material in the hole are limited to before the net is stretched, and the work procedure becomes complicated, the greening of the slope due to the introduction of trees tends to be avoided. is there.

In order to solve the above-mentioned problems, the present invention makes the slope three-dimensionally green so that the lattice-shaped bulging bodies are inconspicuous, and in addition, the forestation of the slope is easily achieved. Be
It provides a greening method on the slope.

[Means for Solving the Problems] That is, in the greening method for the slope of the present invention, a mesh is stretched on the slope, the reinforcing bars are installed in a grid on the mesh, and this grid is used. Mortar or concrete is sprayed on the bar-shaped rebar, and in the greening method of the slope that forms a lattice-shaped bulge, a planting fence that has a large number of openings and forms a storage area for vegetation base material, Adjacent to the reinforcing bars installed in a grid shape, stand up and install in a grid frame made of reinforcing bars, and then spray mortar or concrete on the grid reinforcing bars to form a grid-shaped bulge. Furthermore, in order to prevent the vegetation base material from spilling from the planting fence through the opening , at least
A vegetation bag containing tree seeds, and a vegetation bag connected to the vegetation bag
Mostly, it is a rectangular sheet having an upper side longer than the connecting portion.
After placing the rectangular sheet of Li Cheng vegetation substrate inside the plant栽柵blows vegetation substrate in the bulging body lattice and in the said plant栽柵frame by the upper surface of the vegetation substrate The vegetation bag of the vegetation base is placed on the.

From another point of view, in the greening method of the slope of the present invention, a mesh is stretched on the slope, and the reinforcing bars are installed on the mesh in a grid pattern. In the greening method of the slope where mortar or concrete is sprayed on the rebar to form a lattice-shaped bulge, a planting fence that has a large number of openings and forms a storage area for vegetation base material is grid-shaped. In a state of being adjacent to the swelling body formed in, it is installed by standing up in a lattice-shaped frame by the swelling body, subsequently, vegetation base material spills from the planting fence through the opening. And a vegetation bag containing at least tree seeds,
It is connected to the bag and has an upper side longer than the connecting part.
That after the rectangular sheet of rectangular consisting sheet vegetation substrate was placed inside the plant栽柵blows vegetation substrate in the bulging body lattice and in the said plant栽柵frame by, the vegetation The vegetation bag of the vegetation substrate is placed on the upper surface of the substrate.

According to such a slope greening method, in addition to germination and growth of tree seeds contained in a vegetation bag placed on the upper surface of the vegetation base material sprayed in the planting fence, Even if a rectangular sheet installed inside the planting fence allows the seeds of grass to germinate and grow through the numerous openings in the planting fence, the tree seeds and the grass are substantially swelled in a grid-like frame. Seeds will germinate and grow three-dimensionally, and when the slope is viewed from directly below the slope, the lattice-shaped horizontal frame of swelling bodies will be covered by the above-mentioned three-dimensionally germinated and grown trees and grass. Therefore, the appearance of the slope becomes good in terms of landscape.

In this case, preferably, the planting fence is arranged along the lattice-shaped horizontal frame formed by the bulging body, and the planting fence is also arranged along the lattice-shaped vertical frame, that is, three-dimensionally. Germination
By placing the growing plant on the side of the bulging body that is easily conspicuous so as to cover up the lattice-shaped bulging body as much as possible, by adopting such a construction method, the lattice of the artificial structure The bulging body can be made inconspicuous even at a long distance, and harmony with the surrounding scenery on the slope can be suitably achieved.

In addition, tree seeds are stored in advance in the vegetation bag connected to the rectangular sheet, and the vegetation base material is also sprayed into the planting fence with the rectangular sheet installed inside the planting fence. Since the vegetation bag can be easily placed on the upper surface of the vegetation base material by simply performing the work and bending the vegetation bag along the upper edge of the rectangular sheet, there is no need for difficult digging work that is restricted by the work procedure. As a result, the greening that makes the slope a forest can be suitably achieved.

Further, by installing the rectangular sheet on the planting fence, it is possible to prevent the vegetation base material from spilling from the planting fence through the opening. In particular, the rectangular sheets that are continuous with the vegetation bag and that are longer on both sides than the continuous portion can prevent the vegetation base material from spilling from the sides of the planting fence.
