Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that a straight wall is integrally erected on one side of a 〓-shaped plate with a front plate and a dirt storage part connected to each other. A vegetation block is constructed by forming a straight wall with uneven parts on the upper and lower surfaces, bending the rear end of the soil pool upward, and providing a rising wall with one side connected to the inside of the straight wall. The walls are stacked in multiple stages over the upper surfaces of the straight walls of adjacent vegetation blocks that are connected in a row at the bottom so that the walls are approximately vertically continuous, and are laterally shifted by approximately 1/2 of the thickness of the straight walls, and at the same time in the soil pool area. This relates to a retaining wall block that is filled with soil, and the slope of the filled soil is covered with soil and covered with grass, or is planted with shrubs and flowers, and the weight of the block itself and the load of the soil carried by the block The retaining wall is directly supported by a straight wall that is formed in a nearly vertical continuous manner, creating a stable and solid retaining wall that balances the earth pressure behind the retaining wall. By making it possible to construct a retaining wall without using a retaining wall, and by forming the straight walls that form the block to be tall, the soil reservoir can be filled with a large amount of soil, making up the majority of the surface area of the retaining wall. The aim is to significantly reduce the amount of materials used, and also to restore the natural greenery destroyed by the construction of the retaining wall by covering the front of the retaining wall with greenery.

Conventionally, when a concrete retaining wall is constructed on a newly developed site, the retaining wall part does not blend in with the surrounding natural greenery, resulting in a desolate landscape, and in order to prevent the retaining wall from collapsing due to underground water seepage, an expensive backing such as chestnut stone is placed behind the retaining wall. It is necessary to pour filler material, and since the concrete blocks are installed in series, the entire retaining wall becomes one rigid body, and localized and concentrated earth pressure acts from behind, and the ground below the retaining wall is affected. If the retaining wall rises or sinks, cracks may occur or the retaining wall may be destroyed.

The present invention eliminates such drawbacks, and an embodiment of the present invention will be described in detail with reference to the drawings.As shown in FIGS. A straight wall 3 whose height is approximately twice that of the front plate 1 and whose front corner is missing is integrally erected on one side of the shaped plate formed into the following cross-sectional shape. A convex portion 5 is provided on the upper end surface of the straight wall 3 for fitting the concave and convex portions to prevent the upper and lower blocks from shifting back and forth. A vegetation block 7 is provided with a concave part 6 in the lower end surface of the part 4, and furthermore, the rear part of the earth collecting part 4 is bent upward, and one side thereof is formed into a rising wall 2 connected to the inside of the straight wall 3. form. In addition, as shown in FIG. 6, the front plate 1 and the dirt storage part 4 are connected to each other to form a cross-sectional shape. A straight wall 3 is integrally erected with a bulge 8 protruding obliquely upward in a tip-up manner with the same inclination as that of the face plate 1, and the straight wall 3 is L-shaped when viewed from the front. A convex portion 5 is provided on the upper surface of the rear end, and a recessed portion 6 is provided on the lower surface of the rear end.
A rising wall 2 is provided at the rear of the soil reservoir part 4, and one side thereof is connected to the inside of the straight wall 3 to form another vegetation block 9.

As shown in FIGS. 7 to 8, the vegetation blocks 7... or 9... are placed in the foundation concrete 10.
The first stage is constructed by arranging the blocks consecutively from side to side on the top and filling each soil reservoir 4 with soil 11. Both ends of the lower surface of the soil reservoir 4 of the vegetation block 7 or 9 are horizontally spaced by approximately 1/2 of the thickness of the straight wall 3 so that the straight walls 3 continue approximately vertically across the upper surfaces of the straight walls 3, 3. placed with a shift in the direction, and
The convex portions 5 and the concave portions 6 are fitted in a concave-convex manner to be assembled, and the soil reservoir portion 4 is filled with soil 11. Thereafter, the retaining wall is similarly built in multiple stages up to the top, and the surface of the soil 11 is pounded with soil to grow grass, shrubs, or flowers. In addition, 12 in the figure is Kurite.

Since the present invention is constructed in this manner, the large number of vegetation blocks 7... or 9... constituting the retaining wall have continuity in the vertical and horizontal directions, and are loaded with the own weight of the blocks and the load of the soil 11, and the In this case, the straight wall 3 is directly supported by a so-called buttress that is continuous approximately vertically, and maintains a balance with the earth pressure behind the retaining wall, and the soil 11 is in close contact with the ground behind the retaining wall, resulting in a stable and solid structure. A gravity retaining wall is formed. Furthermore, when using the vegetation block 9, the front plate 1 of the upper block is assembled with the inner surface of the bulge 8 provided at the front end of the straight wall of the lower block, so that the convex part 5 and the concave part 6 are
Coupled with the concave-convex fitting, the connection between the blocks becomes even stronger, which is highly effective in preventing the retaining wall from protruding.

Since the front of the retaining wall is mostly covered with greenery such as mature lawns and shrubs, it harmonizes well with the surrounding nature and preserves the environment. It is possible to construct a retaining wall without installing a retaining wall, which is highly economical, and furthermore, the height of the straight wall 3 is high, and the straight wall 3 is integrally erected on one side of the shape plate,
By making it L-shaped when viewed from the front, the soil reservoir 4 can be filled with a large amount of soil 11, so the number of vegetation blocks 7 or 9 used can be reduced compared to the conventional retaining wall, in which a large number of concrete blocks are placed over the entire surface. Compared to the conventional method, the cost can be significantly reduced and it helps conserve resources.

In addition, the soil reservoir section 4 is filled with a large amount of heavy soil, and by erecting a rising wall 2 connected to the straight wall 3 at the rear of the soil reservoir section 4, it is possible to prevent the bending moment caused by the load. By increasing the resisting section modulus, the soil 11 can be removed without damaging the block.
In addition, since the rising wall 2 and the earth reservoir 4 fill with groundwater, there is no need for artificial watering even during drought periods, and sufficient moisture can be supplied to lawns, shrubs, etc., preventing plant death. This is to prevent it. Furthermore, the soil 11 has abundant capacity, the slope is formed with a gentle slope, and is protected by grass and planted trees, so the soil 11 will not be eroded or washed away by heavy rain. . Since the front panel 1 is tilted forward to face the site below the retaining wall, it disperses and reflects vehicle noise back to its source and prevents it from dispersing into the distance, resulting in a noise level attenuation effect. In addition, the soil 11 and the lush lawns, shrubs, and flowers absorb noise, and the noise is significantly reduced in the area above the retaining wall, and even if localized and concentrated earth pressure is applied behind the retaining wall, it will not be affected. Even if the soil in the area rises, or the ground below the retaining wall rises or sinks, the soil filled in that area will have a buffering effect, and the masonry vegetation blocks themselves will not be affected and cracks will occur in the retaining wall. There is no

As described above, the present invention is an excellent invention that has a simple structure, is suitable for mass production, and contributes to resource saving, and the material of the vegetation block can be made not only of concrete but also of synthetic resin.
