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 frame 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 framework blocks, and involves installing several rhizomes of bamboo cut into appropriate lengths on a special pallet in the space built into the parallel girders. A cassette-type pallet containing grown grass is laid on top of the grass to green the slope, and the grass roots are used to stabilize the ground. Alternatively, after more than 10 years, the bamboo rhizomes embedded in the bottom of the pallet will sprout and the entire ground will become a strong bamboo forest due to the growth of bamboo roots.The purpose is to green the slope. .

To explain the construction method of the present invention with reference to the accompanying drawings, Fig. 1 shows a completed construction in which four cassette-type pallets with grass A are laid in the cavity formed by the concrete method frame 1 constructed in the shape of a parallel grid. This is a perspective view, and construction will be carried out continuously. FIG. 2 is a detailed sectional view showing the 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. Numeral 9 is a bamboo rhizome cut to an appropriate length, and several pieces are embedded in the bottom of pallet 2. 7 is the ground G in the air space of the legal frame 1
This is an organic mat that is laid on the surface of the pallet, on which a thin layer of sand 6 is spread, a net 5 is stretched, and the above-mentioned pallet with grass A is laid on top of it. 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.

In the construction method of the present invention, several cut bamboo rhizomes 9 are embedded in the pallet A with grass, so when the grass begins to wither several years after construction, bamboo buds 10 will emerge from the rhizomes 9. As shown in Figure 4, after more than 10 years, the entire area will turn into grass and become a bamboo forest, making the slope even stronger.

Since the pallet 2 used in the present invention is made of a thin board 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 to the ground. In addition, the organic mat 7 placed under the pallet has a thickness of approximately 3 mm, and covers the entire surface of the ground, smoothing out the uneven surfaces of cutting and embankment, and bringing it into close contact with the ground to ensure the stability of the pallet 2. It also has the effect of retaining rainwater and topsoil, retaining geothermal heat, and preventing erosion of topsoil.As it is an organic material, it is completely composted and returned to the soil within one to two years after being laid. Furthermore, the net 5 is made of synthetic fiber and is effective in strengthening the connection of the grass roots, fixing the pallet 2 on the ground, and distributing water evenly for the purpose of curing the grass. The type of bamboo to be used is not particularly limited, but medake, hachiku, and bamboo grass are suitable because they grow quickly.

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 sowing seeds on-site and growing them, greening can be completed in a short period of time as they adapt to the soil and are not affected by the condition of the soil on the slope or natural conditions.
The construction is extremely quick and easy, as it only requires simple preparation and laying out the grass-grown pallets A. After construction, a slope with lush grass will be formed, and it will last for several years. This transforms into a bamboo forest, greening the slope and making the ground even stronger, an outstanding effect never seen before.

Claims (1)

[Claims] 1 A pallet with turf, which is formed into a square thin plate shape using a synthetic resin lattice mesh board, and several bamboo roots cut to an appropriate length are arranged at the bottom of the pallet, and grass with post-cultivation soil is spread over the bottom of the pallet. A is made into one unit, an organic mat is laid on the surface of the space formed by the concrete frame 1, sand is spread on it and a net is placed on it, and the pallet A with grass is placed on top of it. This is a method for greening concrete frames that uses grass as a filler material for concrete frames, which is characterized by laying four sheets side by side and constructing them continuously.
