Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforced soil wall structure in which the growth of plants planted on the surface layer of an embankment is improved.

[0002]

2. Description of the Related Art FIG. 23 shows an example of a conventional example of a reinforced earth wall structure constructed as a retaining wall facing a road, a residential area, and the like. It is installed while being connected to each other, thereby constructing an embankment wall surface A that is continuous in the vertical direction and the lateral direction. The back of the embankment wall surface A is filled with the embankment 31 made of excavated soil generated in large quantities while being rolled. ing.

In the embankment 31, an embankment reinforcing material 32 for fixing the wall panel 30 to the surface layer of the embankment 31 is buried, while preventing the embankment 31 from subsidence, movement, runoff and the like. As the material 32, a steel material, a reinforcing bar, a wire mesh, a geotextile, or the like is used.

[0004]

However, the wall panel 30
Since it is mainly made of reinforced concrete and is extremely heavy, it is difficult to install the wall panels 30 one by one while fixing them with the embankment reinforcing material 32. Particularly, the wall panels 30 are subjected to a considerable earth pressure. Therefore, since it is formed thick to have sufficient strength, the weight further increases, and handling such as transportation and installation is difficult.

Furthermore, since the surface of the embankment 31 is completely covered with the wall panel 30, there is another problem that the surface of the embankment 31 cannot be greened by planting at all.

Accordingly, the applicant has set up a wire mesh or a reinforcing grid as the wall surface panel 30 to reduce the weight by exposing the surface of the embankment 31 and also to make the soil reinforced by planting green. We have proposed a wall structure and have already filed an application.

[0007] However, in this type of reinforced soil wall structure, the workability can be improved by weight reduction and greening can be achieved by planting, but a sufficient amount of solar radiation cannot be obtained because the embankment wall surface is inclined. . For this reason, even if the surface of the embankment 31 is planted and greened, the subsequent growth of the vegetation is poor, and there is a possibility that the vegetation may easily be washed away by rain, and there is a problem that reliable greening cannot be performed. .

[0008] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a reinforced earth wall structure capable of reliably performing greening.

[0009]

In order to solve the above-mentioned problems, a reinforced earth wall structure according to the present invention is characterized in that a plurality of embankment wall materials for holding an embankment are connected to each other in a vertical direction and a horizontal direction. And it is set up while gradually retreating to the embankment side as it becomes the upper stage, constructing a stepped embankment wall, filling the back of this embankment wall so that the surface layer forms a step along the embankment wall surface The embankment is constructed by holding the embankment in the embankment, embedding a plurality of embankment reinforcing materials for fixing the embankment wall material at a tip portion thereof, and planting vegetation on a flat portion of the embankment surface layer portion.

[0010] At this time, the embankment wall material includes a wall portion attached to the surface of the embankment, and a leg portion horizontally projecting into the embankment from a lower end portion of the wall surface portion and connected to the embankment reinforcing material. It is good to be formed in a substantially L-shaped section.

It is preferable that a connecting portion protruding toward the embankment side and connected to an embankment wall material positioned above is formed at an upper end portion of the wall surface portion. In addition, embankment wall material,
It may be formed in a convex curved shape.

[0012] Further, it is preferable that all the embankment reinforcing members are formed of reinforcing bar grit. Furthermore, when the wall surface is formed of a reinforced concrete panel, and the wall surface is formed of reinforced grit, a concrete panel, a concrete block, or pseudo-natural stone may be added to the wall surface.

[0013]
