[0009]

1 to 5 show an embodiment of a greening block according to the present invention. A greening block 1 is a concrete block having a square front surface, and the entire greening wall is inclined.
On the front surface forming the slope, a slope 2 is formed which is inclined upward from below and inclined by an angle θ toward the rear surface.

The slope 2 is one for one green block 1.
Although only the steps may be provided, if the height of the greening block 1 and the front-rear width of the lower surface are the same, it is preferable to provide a plurality of steps with upper and lower steps as shown in FIG. Is preferable because the upward angle θ can be made large (the slope 2 approaches horizontal).

The slope 2 is a vegetation for filling a plant culture material 3 such as a solid plant culture material 3 made of a mixture of organic matter, soil particles and fertilizer and pressed into a cubic form, or a general particulate soil. A recess 4 is formed.

The vegetation recess 4 has an L-shaped vertical section in which the bottom of the lower bottom surface 4a is deeper than the upper bottom surface 4b.

The greening block 1 is provided with a filler filling hole 5 penetrating from the upper surface to the lower surface, and has a longitudinal groove 6 on both sides and a lateral groove 7 on the lower surface. On the upper surface, a left-right ridge 8 is formed to fit closely into the concave groove 7 on the lower surface.

Between the lower bottom surface 4a of the vegetation recess 4 and the rear surface of the greening block 1, groundwater or the like from the ground is filled with the vegetation recess 4.
The water supply hole 4c for taking in inside is provided.

When greening is performed on the greening wall 9 such as a retaining wall, a bank or slope of a river, or a wall of a sabo dam using the greening block 1 configured as described above, FIGS.
As shown in FIG. 8, the greening blocks 1 are installed in a staggered manner at the top, bottom, left, and right to form a greening wall.

The upper and lower greening blocks 1 and 1 are positioned so that they do not shift back and forth by fitting a ridge 8 on the upper surface into a concave groove 7 on the lower surface. 5 is passed through a reinforcing bar 10 and then filled with a solidifying material 11 such as concrete or mortar to be integrated.

Greening blocks 1, 1 joined to the left and right
The two are integrated by filling a consolidation material 12, such as mortar, into the concave grooves 6, 6 that are united on the respective side surfaces.

By arranging the greening blocks 1 having the illustrated dimensions in a staggered manner, the left and right ends of the greening wall become irregular. In this irregular part, the greening block 1 ′ has a horizontal width that is half that of the greening block 1. To align the edges in a straight line.

It is more reasonable to fill the vegetation recess 4 with the plant culture material 3 at the time of installing the greening block 1 and to plant the plant seeds and seedlings. To fill plant seeds or seedlings,
A plant seed or a hollow may be planted on the plant culture material 3 filled before the greening wall is built after the greening wall is built.

As described above, the greening wall thus constructed is planted on the plant material 3 in the vegetation recess 4 because the slope 2 of the greening block 1 is gentle even if the installation wall is steep. The growth of the plant obtained is stabilized, and the erosion and outflow of the plant culture material due to wind and rain can be reduced.

[0021]

As described above, according to the present invention, the greening wall surface
Because the slope that slopes upward from the bottom to the rear side is formed on the front surface that forms the entire slope, the slope of the greening block is gentle even if the slope of the greening wall is steep, The growth of the plant planted in the plant culture material in the vegetation recess is stabilized, and the erosion and outflow of the plant culture material due to wind and rain can be reduced.

By providing the slope with a plurality of steps with upper and lower steps, if the height of the greening block and the front-to-rear width of the lower surface are the same, a large upward angle with respect to the rear surface can be taken (the slope approaches horizontal). ), The effect of stabilizing plant growth and preventing the outflow of plant culture materials is improved.

The vegetation concave portion is formed in an L-shaped vertical section having a lower bottom portion deeper than the upper portion, so that the lower portion of the lower bottom can hold a large amount of water necessary for plant growth. At the same time, the rooting area of the plant can be increased.
