Inclining with respect to the lower soil retaining plate 2 and arranging so as to overlap in the vertical direction,
In addition, there is a space 8 which can be planted between the lower soil retaining plate 2 and the first upper soil retaining plate 6 and between the first upper soil retaining plate 6 and the second upper soil retaining plate 7. By connecting and fixing together,
A retaining wall A is formed.

Next, the operation of the embodiment will be described. The retaining wall A of the present invention may be entirely constructed at a construction site where planting is performed, or all or a part of the retaining wall A may be manufactured in a factory and assembled at the construction site, and the retaining wall A is used as a planting surface. After installation, as shown in FIG. 4, soil 9 is embedded in the gaps 8, and then trees 10 are planted in the gaps 8. According to the retaining wall A of the present invention, soil retaining can be performed without loosening the frontal slope of the retaining wall A, and the soil 9 in the spacing portion 8 is deeply formed. It can be planted. Further, since each soil retaining plate is recessed downward toward the rear surface of the soil retaining plate, if the upper portion of the soil retaining plate is aligned with the vertical line, it becomes a vertical soil retaining system. Soil retention can be done.

The lower soil retaining plate 2 and the first and second upper soil retaining plates 6 and 7 may be of any strength so long as they can support the soil on the back surface, and their shape and surface finish are arbitrary. The number of earth retaining plates located in the middle tier does not matter. Further, the shape, position, degree of inclination, and number of each earth retaining plate are not limited as long as the requirements such as stability, strength and durability of the retaining wall are satisfied.

Further, the lower end 6a of the first upper upper soil retaining plate 6
Is lower than the upper end 2a of the lower soil retaining plate 2, and the lower end 7a of the second upper soil retaining plate 7 is the upper upper soil retaining plate 6 of the first stage.
Are arranged so as to be located below the upper end 6b of each of the above, but at that position, the soil 9 on the back side supported by the upper soil retaining plates 6 and 7 of the first and second stages is the weight and the retaining wall. Due to the load placed on the upper ground 11, the space between the lower soil retaining plate 2 and the first upper soil retaining plate 6 and the first upper soil retaining plate 6
And the soil 9 in the space 8 between the second upper soil retaining plate 7 and
It is necessary to have a position where it can sufficiently resist so that it does not rise or flow out. Then, in order to increase this resistance, the reinforcement backing material 12 that is hard to collapse, rise, and flow out or the reinforcement beam 5 is provided in consideration of the soil quality and the structural balance of the soil 9 on the back surface.

Further, the wall 4 is composed of a bottom plate 1, a lower slab 2,
First-stage upper retained plate 6 and second-stage upper retained plate 7
Stabilize the retaining wall A by connecting with, and serve as a fulcrum for the lower soil retaining plate 2, the upper soil retaining plates 6 and 7 of the first and second stages, and the lower soil retaining plate 2
And the upper soil retaining plates 6 and 7 of the first and second stages. And the number of this ridge wall 4 should just be the number which fits the size of the retaining wall A, and it is not necessary to limit the number.
Further, the shape of the siding wall 4 may be any as long as it satisfies the strength of the retaining wall A, and its shape and dimensions are not limited.

FIG. 7 is a vertical cross-sectional side view showing another embodiment in which the retaining plate A is a retaining wall A having four steps and has a shape different from that of the lower retaining plate 2 shown in FIGS. Is.

Retaining wall A consisting of four steps of retaining plates shown in FIG.

So that the first upper soil retaining plate 27 and the second upper soil retaining plate 28 are penetrated, and the third upper soil retaining plate 2
9 is fixed on each siding wall 26 so as to be flush with the tapered surface 25, and has an interval portion 30 which can be planted between each earth retaining plate and is integrally connected and fixed, A wall A is formed.

Also in the case of this embodiment, it is the same as in the case of FIGS. 1 to 6 that the lower end of the upper earth retaining plate is located lower than the upper end of the lower retaining plate. . Reference numeral 31 in the drawing is a reinforcing beam and has the same function as that in FIGS.

[0017]

Since the present invention is as described above, it is possible to retain the soil without loosening the front slope of the retaining wall as in the conventional case, and the lower end of the upper retaining plate is lower than the retaining plate of the lower retaining plate. Since it is located below the upper edge, backfill soil collapses,
There is no depression and the soil on the back of the soil retaining plate does not flow out, and there is soil between the upper soil retaining plate and the lower soil retaining plate, which is continuous with the soil on the rear side, so it is necessary to replenish water. It is possible to plant in this part, and since the soil in this part is deep to the structure that blocks the bottom part, it is possible to plant tall trees while the root becomes deep. Then, the front surface of the retaining wall can be covered sufficiently with plants, and the front slope of the retaining wall can be made vertical. Therefore, if the front line is aligned with the land boundary line, the land above the retaining wall will be used up to the boundary line. A retaining wall can be obtained, and if necessary, an overhanging green retaining wall can be used to widen the range of effective use of the ground above the retaining wall.
