DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening retaining wall that covers a river embankment and other slopes with a concrete block, and also performs greening by vegetation.

[0002]

2. Description of the Related Art Conventionally, as a greening retaining wall on a slope, a concrete block having a vegetation soil receiving portion penetratingly opened on the back surface is arranged on the ground surface to form a retaining wall, and the vegetation soil receiving portion is mixed with soil and fertilizer. BACKGROUND ART A greening retaining wall in which soil is filled to grow plants such as lawns is known.

[0003]

When the above-mentioned conventional greening retaining wall is used, for example, for greening a river embankment, when the water rises about several times a year, the retaining wall in the vegetation soil accommodating portion is sucked by flowing water. The vegetation soil has been washed away along with the roots of vegetation such as grasses, and there has been a problem that the vegetation soil must be refilled and vegetated again to recover.

The present invention has been made in view of such a conventional problem, and has as its object to provide a slope greening retaining wall structure in which vegetation soil and vegetation are not washed away even when exposed to running water.

[0005]

SUMMARY OF THE INVENTION In order to solve the conventional problems as described above and to achieve the intended object, the gist of the present invention is to provide a concrete having a vegetation soil accommodating portion having a through opening on both sides. Blocks are laid side by side on a slope, vegetation soil is filled in the vegetation soil accommodating section, and a plurality of vegetation-sloping retaining walls formed by vegetation have flexibility at an intermediate height position on the inner surface of the vegetation soil accommodating section. The linear material is protruded, and a porous solid base material also serving as a fertilizer mainly containing an organic fiber material is accommodated in a portion deeper than the linear material, and the linear materials are fixed to each other on the outside thereof to form the porous material. While keeping the solid base material
Lies around and slope greening retaining wall comprising a feature that it has filled the vegetation soil on the outside of the porous solid substrate.

[0006]

The greening retaining wall of the present invention can be easily inserted by bending a linear material when inserting a porous solid base material mainly composed of an organic fiber material and also serving as a fertilizer. As a result, the porous solid base material is prevented from falling off, and is buried in vegetation soil such as earth and sand in this state. When vegetation is applied to the vegetation soil, the roots of the plant enter the porous solid base material and are difficult to separate, thereby preventing runoff even before the roots are sufficiently established. On the other hand, the porous solid base material rots over time to become fertilizer, but at that time, the roots of the vegetation are sufficiently stretched to form a demon, which is prevented from falling off by the linear material, and is prevented from being washed away. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

In the drawing, reference numeral 1 denotes a concrete block. This block is chamfered on a square corner,
Are formed, and triangular recesses 3, 3, ... are formed in the center of each side in four directions, extending over the front and back sides.
The joining surfaces 5 and 5 are formed on both sides of the concave portion 3 for each side. In the center of the block 1, the corners are directed toward the joining surface 5.
, And a vegetation soil storage part 7 at the center thereof and facing in the same direction. Each of these vegetation soil storage portions 6 and 7 has a tapered shape whose surface is expanded as shown in FIG.

Further, the corners 6a, 6a,... Facing the joint surfaces 5, 5,... Of the vegetation soil receiving parts 6, 6,. Bolt insertion hole 7
Are formed horizontally.

The blocks 1 configured as described above are arranged on the surface of the slope, and the joining surfaces 5 and 5 are joined and laid.
The connecting bolts 9 are inserted into the bolt insertion holes 8 and 8 across the blocks 1 and 1 on the adjacent joint surfaces 5 and 5 and fastened in the vegetation soil receiving portions 6 and 6. At the time of fastening of the bolt 9, each corner portion 6a is applied with an applicator 10, 10 made of an elastic material such as rubber, synthetic rubber, or wood.
A bolt 9 is inserted through this, and a nut 11 is inserted into one end.
Are screwed and fastened.

In this manner, the blocks 1, 1,... Are connected to each other by the bolts 9 so that the lining is performed by a single disk-shaped block.

At this time, as shown in FIG. 3, a vegetation soil accommodating portion 12 surrounded by chamfers 2, 2,... Is formed between four adjacent blocks 1, 1,. A vegetation soil accommodating portion 13 formed by the concave portions 3 and 3 is formed between the blocks 1 and 1.

Each of these vegetation soil storage units 6, 7, 12, 1
An intermediate height position within 3, toward the center ...... linear member 14 and 14 with a flexible than the block 1 are a plurality of increments projects. The wire members 14 are made of steel wire, iron wire or the like as an example, and the wire members 14 are twisted at the center portion of each vegetation soil accommodating portion so as to be fixed to each other.

As shown in FIG. 4, the vegetation soil receiving portions 6, 7, 12, 13 provided on the retaining wall constituted by arranging the blocks 1, 1... First, the porous solid base material 15 is accommodated in the inner part thereof, and the linear solid materials 15 are stopped by fastening the linear members 14 and 14 outside thereof. Next, vegetation soil 16 is filled around and outside, and vegetation is applied. The porous solid base material 15 is mainly composed of an organic fiber material such as plant stems and twigs, mixed with organic and inorganic fertilizer components, and hardened to a porous shape by a binder.

By applying vegetation in this way, the roots of the vegetation cover the vegetation soil 16 and at the same time the porous solid substrate 1
5 and then fit together, whereby the whole is integrated and prevented from falling off by the linear material 14. Also porous solid
After Katachimotozai 15 was fertilizer and corruption, linear member 14
The roots extend further into the back and enclose the linear material 14,
Thereby, the retaining is maintained.

[0016]

As described above, in the slope greening retaining wall of the present invention, a linear material is protruded into a vegetation soil accommodating portion formed on a retaining wall made of a concrete block, and a porous solid base material is provided behind the linear material. By holding the /> and retaining it with the linear material, and embedding it in vegetation soil to perform vegetation, even during the growth of vegetation, and also after the rot of the porous solid substrate , The retainer is effectively prevented from being lost even by the suction effect of running water.
