DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening method using a retaining wall block and a greening block used in the method.

[0002]

2. Description of the Related Art When a retaining wall is constructed with a conventional greening block, a greening block is installed at a cutting step provided on a retaining wall construction surface and filled with earth and sand to construct a retaining wall.

[0003]

In the above-mentioned conventional construction method, there is a case where the earth and sand fall down or run off under the influence of seepage water from the ground. The present invention has been proposed in view of the above-mentioned problems of the prior art, and its purpose is to prevent run-off of earth and sand, and to be used in a greening method having excellent workability and a greening method. Another object of the present invention is to provide a greening block in which the amount of concrete is small, the amount of sediment in the body is large, and the planting area can be as large as possible.

[0004]

In order to achieve the above object, according to the tree planting method according to the present invention, a vertical surface and a bottom horizontal surface of each of the cutout steps for block installation provided on the slope for retaining wall construction. In order to prevent the permeation of earth and sand, each of which has water permeability, a sheet for preventing the loss of the earth and sand for planting is arranged, and a greening block is installed at each of the steps, between adjacent blocks and between the same blocks. The back is filled with planting soil.

In the greening block according to the present invention, the horizontal sleeve pieces extend from the base ends of both ends of the arch-shaped curved portion bulging at the center of the front part, and a pair of square frame pieces project from the rear face. The horizontal connecting pieces are connected between the rear ends of the rectangular frame pieces.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing preferred embodiments of the present invention. Reference numeral 1 denotes a cut-out step for installing a block provided on a slope for retaining wall construction. The cut-away section for planting is composed of a nonwoven fabric or the like on the back vertical surface 1a and the bottom horizontal surface 1b of each of the cut-off steps. Sheet 2
a, 2b are attached.

A greening block 3 has an arched curved surface portion 3a bulging at the center of the front surface, horizontal sleeve pieces 3b extending from both ends of the base of the arched curved surface portion 3a, and the block front surface has a pseudo-stone pattern. Is formed. A pair of rectangular frame pieces 3c are horizontally protruded from the back surface of the arched curved surface portion 3a, and a horizontal connecting piece 3d is connected between the distal ends of the rectangular frame pieces 3c.

The greening blocks 3 of the respective stages are installed in the cut-off step portion 1. The horizontal sleeve pieces 3b, 3b of the adjacent blocks 3 on the same step portion abut against each other, and the vertically adjacent blocks are It is layered so that it is located at half the length of the block width and is misaligned on the left and right. Thus, the soil 4 for planting in the space formed between the arched curved surface 3a, the horizontal sleeve 3b, and the rectangular frame 3c in each of the blocks 3 vertically and horizontally adjacent to each other.
Fill.

According to the embodiment shown in the drawings, planting is made of a nonwoven fabric or the like on the back vertical surface 1a and the bottom horizontal surface 1b of the step provided on the retaining wall construction slope for installing the greening block 3. Since the sheets 2a and 2b for preventing the body soil from flowing out are attached, the sheet allows water to permeate but does not allow earth and sand to pass through, so that there is a possibility that the body sediment 4 will fall or be washed away by infiltration water. Absent.

[0010] Further, the front surface of the greening block 3 bulges into an arch-shaped curved surface, and a pair of rectangular frame pieces project horizontally from the back surface of the curved surface portion, thereby reducing the amount of concrete used for the block. As a result, the amount of the embankment 4 is increased.

[0011]

As described above, in the greening method according to the present invention, the blocks are not directly installed on the greening block setting cutting steps provided on the retaining wall construction slope, but each back of the cutting steps is provided. By arranging a sheet for preventing spillage of planting yard sediment that has water permeability in the vertical plane and the bottom horizontal plane but prevents sediment penetration, and installing a greening block at each of the cutting steps, Does not fall down under the influence of seepage water and is prevented from spilling.

Further, according to the present invention, the soil for planting can be filled between the adjacent greening blocks and on the rear surface of the greening block having an arch-shaped bulging portion on the front surface, so that the amount of sediment in the body can be reduced. Can be increased as much as possible, so that the amount of vegetation piled in can be increased as much as possible, and according to the present invention, the greening block has a horizontal laminated structure, so that the workability is greatly improved.

The greening block according to the present invention allows the planting area to be as large as possible by bulging the arch-shaped curved surface portion at the center of the front portion, so that a large plant can be planted. Also, horizontal pieces project from the base ends of both ends of the arch-shaped curved part, the horizontal pieces of adjacent greening blocks are connected, and one pair of square frame pieces project from the back of the arch-shaped curved part. Since the horizontal connecting pieces are connected between the rear ends of the frame pieces, when the greening block of the present invention is provided, a lattice frame-like frame structure is formed, and the amount of concrete is reduced. At the same time, the amount of sediment piled in increases, the planting effect is improved, and a retaining wall configuration of a horizontal stacked structure with excellent workability is configured.
