Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a concrete legal framework block that is laid for retaining earth on a slope of cut or embankment formed by road construction, embankment construction, etc. This article relates to a method of greening a slope using grass as a filling material.

Normally, this type of sill block is constructed of concrete members in the shape of a parallel grid, and the space built into the parallel grid is usually left bare earth. Therefore, if damage occurs during heavy rains, there is a risk that the earth and sand in the spaces will flow out, loosening the foundations of the slope blocks built to retain the earth, and causing the slope to collapse. Furthermore, even if this situation has not yet been reached, the skin of the skin is still exposed, resulting in a landscape that is unsightly and does not match the natural environment.

The present invention aims at greening such unnatural concrete slope blocks by laying grass grown on special pallets in a cassette style in the air space built into the cross beams. The purpose is to promote greening and stabilize the ground through the rooting of grass.

To explain the construction method of the present invention with reference to the attached drawings, the first
The figure shows a completed perspective view of four cassette-type grass pallets A being laid in the space formed by the concrete slope 1 constructed in the shape of a parallel grid. Do it continuously. FIG. 2 is a detailed sectional view of pallet A with grass and its laying structure. In the figure, 2 is a pallet formed into a square thin plate shape using a grid-like mesh board made of synthetic resin, and 3 shows grass grown through culture soil 4. One unit of pallet A with grass is shown. Configure. 7 is an organic mat that is laid on the surface of the ground G in the empty space of the legal frame 1, and a thin layer of sand 6 is placed on top of this.
The above-mentioned pallet with grass A is laid on top of the net 5. As shown in the figure, it is appropriate to lay four sheets in a row in the cross-shaped space of one concrete legal frame 1, from the point of view of construction, or from the point of view of repair and replacement when the grass dies. ing. Fig. 3 is a construction drawing of the construction method of the present invention, showing a means for arranging pallets A with grass on a slope within a frame 1 and fixing them with anchor nails 8 to prevent the pallets A from moving on the slope. There is.

Since the pallet 2 used in the present invention is made of a thin plate made of vinyl chloride with semi-permanent durability and has a lattice-like mesh, the turf 3 has sufficient rooting through the cultivation soil 4 when it is laid. After construction, the roots of the grass penetrate the pine 7 laid below and spread out on the ground. In addition, the organic mat 7 placed under the pallet has a thickness of about 3 mm and covers the entire surface of the ground, smoothing out the uneven surfaces of cutting and embankment and making it stick tightly to the ground, improving the stability of the pallet 2. It also has the effect of retaining rainwater and topsoil, retaining heat and heat, and preventing erosion of topsoil.As it is an organic material, it will be completely composted and returned to the soil within a few years after being laid. In addition, Net 5 is made of synthetic fiber and strengthens the connection of grass roots.
It is effective in fixing the pallet 2 on the ground and evenly distributing water for lawn care.

As mentioned above, the frame greening method of the present invention uses the pallet A with grass that has already been sufficiently grown in the nursery, so it is different from the conventional turf method of planting natural grass,
Alternatively, compared to the method of growing from seeds, greening can be completed in a short period of time as it adapts to the soil and is not affected by the state of soil damage on the slope or natural conditions. The installation is extremely quick and easy as it only requires simple preparation and laying out the pallets A with grass on which the grass is growing, and even if the grass dies after installation, all you have to do is replace the pallet in that area. It has the outstanding effect of being able to be repaired, completely greening slopes that used concrete slopes that were not compatible with the natural environment, and achieving ground stability.

Claims (1)

[Claims] 1. A pallet with grass A, which is a pallet formed into a square thin plate shape using a synthetic resin lattice mesh board and covered with grass with cultivation soil, is used as a unit, and a space formed by a concrete method frame 1 is used. Concrete characterized in that an organic pine is laid on the surface of the concrete, sand is spread on it and a net is stretched over it, and then four of the above-mentioned pallets with grass A are laid out and laid out in a row, and these are successively constructed. Law frame greening method that uses grass as filling material for the law frame.
