Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawn retaining wall provided with a terrace-like vegetation pot capable of protecting a sloped surface such as a mountain or a slope, and providing vegetation of middle shrubs on the surface. .

[0002]

2. Description of the Related Art Conventionally, there is a so-called method-frame method as a method for protecting a slope formed by excavation of a ground or earthworks such as embankment or a steep ground such as a steep ground.

In this method, a grid-like legal frame composed of a horizontal frame material and a vertical frame material is installed on the surface of an inclined ground. The surrounding area is filled with soil, vegetation is vegetated, greening is performed, and the surface of the slope is strengthened.

[0004] On the other hand, when the slope is steep, the inside of the grid of the frame is closed with a concrete slab, and the entire surface is made of a concrete retaining wall.

[0005] When the sloping walls are covered with concrete or the slope is made of rocky or gravel, the soil cannot be fixed as it is, and sufficient vegetation soil for vegetation cannot be obtained. Could not be retained.

Therefore, in recent years, on the surface of the legal frame retaining wall on which such soil cannot be fixed, the earth retaining wall is erected integrally with the vertical frame member and the horizontal frame member, and a terrace-like vegetation pot is installed. In addition, a pot for terraced vegetation which aims at greening has been developed (Japanese Patent Application Laid-Open No. 1-223218).

[0007]

The above-mentioned conventional retaining wall with a vegetation pot has a pot retaining wall integrally formed with the respective frame members by cast-in-place concrete when the conventional framing pot with a vegetation pot is cast in place. . This was due to the fact that the shape of the sloped ground surface on which the lawn frame was installed was not uniform, and therefore the lawn frame itself often did not have a uniform and regular lattice shape.

For this reason, it is necessary to construct a concrete formwork at the construction site for each vegetation pot and to perform cast-in-place concrete, which increases the number of work steps on the site, requires a lot of labor, increases the construction period, and precasts. There was a problem that construction could not be performed on a block-shaped frame retaining wall.

In view of such a conventional problem, the present invention can be carried out regardless of a concrete frame made of cast-in-place concrete or a legal frame using a precast member. The purpose of the present invention is to provide a method frame retaining wall with a terrace-shaped vegetation pot that can easily attach a high-strength terrain vegetation pot in a short time without requiring any molding work such as installation. Things.

[0010]

A feature of the present invention for achieving the above-mentioned object is that a grid-shaped concrete manufacturing frame is installed on the sloped ground surface, and each horizontal frame member and each vertical frame of the law frame are provided. A pot retaining wall is erected from the lower horizontal frame material and the left and right vertical frame portions surrounded by the material to form a terraced vegetation pot with an open upper part, and vegetation soil is filled in the pot. In a legal frame retaining wall with a pot for terraced vegetation to be accommodated, the retaining wall is erected with the lower edge fixed to the left and right vertical frame members, and a large number of plate materials are combined in a grid-like grating.
And wood, lies in the construction with the impermeable sheet superposed on the inner side of the grating material.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

In FIG. 1, reference numeral 1 denotes an inclined ground, and reference numeral 2 denotes a concrete frame installed on the surface thereof. This method frame 2 may be either a combination of precast blocks or a unit formed by cast-in-place concrete.

The method frame 2 has vertical frame members 2a, and the transverse frame member 2b configured by arranging in a grid pattern.

A vegetation pot 4 having a terrace shape is provided in every other grid of the retaining wall. Vegetation pot 4
Is constructed by standing up a pot retaining wall 5A having a plane-like continuous shape from a horizontal frame member 2b and vertical frame members 2a, 2a on both left and right sides thereof.

The pot retaining wall 5A is made of a rectangular metal plate.
Vertical members 10a and horizontal members 10b made of
It is composed of a grating material integrated together and a water-impermeable sheet 7 such as a resin film laminated on the inside thereof. This grating material is provided on both sides of the front member 11.
Fix the side members 12 and 12 to the back of the
Standing up. And the lower edge of the front part 11 is
The lower edge of the side member 12 is brought into contact with the upper surface of the
Into the inside of the vertical frame material 2a, and hold the bolt 8 to
2a, 2a.

A vegetation pot 9 constructed as described above is filled with a vegetation soil 9 mixed with a necessary fertilizer component, and a middle shrub is planted.

In order to connect the front member 11 and the side member 12, a folded plate-shaped stopper 13 fitted in the lattice of the front member 11 is used. 15 and the vertical member 10 on the end face of the side member 12.
Both are fastened to each other by being screwed into a nut 16 fixed to the back surface of a. And this bolt 15
By loosening the distance between the side members 12, 12, the distance between the vertical frame members 2a, 2a can be adjusted.

In this embodiment, the vegetation pot 4
Concrete panel 3 in the grid position for installing the is a part or by punching a whole is continuously and slope panel 1 and vegetation soil 9.

[0021]

[Effects of the Invention] As described above, the terraced vegetation potted frame wall of the present invention is obtained by combining a pot retaining wall constituting a terraced vegetation pot with a large number of plate materials in a lattice shape.
Because it is composed of a grating material and an impermeable sheet stacked on the inside, the shape can be easily adjusted according to the shape of the installation location, and as a result, it can be easily adapted to various shapes of legal frames Can be.

Further , since the mounting is performed by means of fixing means such as bolts, the mounting can be easily performed with a small amount of labor, and the construction can be performed in a short time and at low cost.

Further, the shape retaining property of the grating material is high.
As a result, a high-strength terraced vegetation pot is
In addition, the work is facilitated by the lightweight grating material.
