A plurality of plants 11 are planted on the soil 10.

Here, the stacked retaining wall forming units 5... Are constructed so that optimal solar radiation can be obtained, and that rainwater from above flows smoothly downward and spreads over the whole. The planted plants 11 grow in a short period of time. Therefore, retaining wall forming unit 5 in a short period of time
・ The natural environment will be completely covered and completely different from ordinary forests.

[0007] In addition, the grown plants 11 ... absorb the noise, and also play the role of a soundproof wall, a sound insulating wall or a sound absorbing wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a prototype inclined portion. The prototype inclined portion 1 is formed in advance, and is formed to have an existing steep ascending slope. A foundation 2 made of concrete is provided outside the lower end of the prototype inclined portion 1.

As can be understood from FIG.
The prototype inclined portion 1 is formed to be thicker and thinner toward the outside. A base member 4 made of concrete or the like is provided on the foundation 2. The base member 4
A base surface 3 having an inclination angle substantially equal to the inclination angle of the prototype inclined portion 1 forming a steep ascending slope is formed at an upper end thereof.

On the base surface 3, a plurality of retaining wall forming units 5 are stacked and mounted. As shown in FIG. 2, the retaining wall forming units 5 are arranged side by side in parallel, and a pair of legs 6, 6 each forming a substantially clogged blade shape from the base end toward the lower end thereof are formed. Provided,
Further, the leg portions 6 are formed integrally with the pair of leg portions 6 and extend from the upper surfaces of both ends of the leg portions 6 and 6 in a direction substantially orthogonal to the leg portions 6 and rise up to the leading end side in the width direction. It is formed with a pair of overhanging pieces 8a and 8b having a rising portion 7.

Therefore, the retaining wall forming unit 5 is provided with a central cavity 9 which penetrates from the upper part to the lower part in the central part. Further, the retaining wall forming units 5 are stacked as shown in FIG. 1, but the upper retaining wall forming units 5 to be stacked are smaller or equal in size to the lower retaining wall forming units 5 located below. There is.

As shown in FIG. 1, the retaining wall forming units 5 which are stacked in a plurality of stages have an inclination substantially equal to the inclination of the above-described prototype inclined portion 1. As shown in FIG. Further, in the stacking of the retaining wall forming units 5, the inclined side of the prototype inclined portion 1 is aligned in a substantially straight line, and the outer side is stacked in a substantially stepped shape.

By such stacking, the center of gravity of the retaining wall basic portion is filled with the earth and sand 10 between the prototype inclined portion 1 and the retaining wall basic portion from the prototype inclined portion 1 side. Even if pressed outward, the retaining wall forming unit 5
-The retaining wall basic body 13 formed by stacking is not collapsed. Next, the central void 9 in the retaining wall basic body 13 formed by the stacked retaining wall forming units 5..., The inner position 12 of the outer projecting piece 8a, and the formation of the retaining wall stacked as described above. The earth and sand 10 are filled between the unit 5... And the prototype inclined portion 1.

Next, as can be understood from FIG. 1, a plurality of plants 11.
・ ・ Is planted. However, since the outside of the basic portion of the retaining wall is substantially stepped as described above, the exposed area of the filled earth and sand 10 is sufficiently secured at the outer portion, and many plants 11 are planted there. At the same time, good sunlight can be given to the plants 11.

Thus, according to the present invention, the planted plant 1
.. Can be considered to obtain good sunshine, and rainwater from above flows smoothly downward when it rains, and is spread over the entire planted plant 11. is there. Therefore, planted trees 1
1 completely covers the stacked retaining wall forming units 5 in a short period of time. In particular, the outer projecting pieces 8a of the retaining wall forming units 5...

However, with such a retaining wall, the vegetation 11 absorbs various noises without reflecting the noise, and also has a function as a soundproof wall, a sound insulating wall, or a sound absorbing wall. In addition, it can be a natural retaining wall rich in greenery without destroying the natural environment. Further, the planted trees 11 are deeply rooted to a position near the base member 4, whereby a stronger retaining wall can be constructed.

[0017]

As described above, according to the retaining wall of the present invention, the natural environment is not destroyed, and after the construction, the building is covered with a sufficient amount of green in a short period of time like a forest, and the soundproofing of the vegetation. An excellent effect such as an effect, a sound insulation effect or a sound absorption effect is taken into consideration, and the structure is firmly built for a long period of time.
