Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sloped green retaining wall for protecting slopes such as embankments and cuts by blocks made of precast concrete and for greening by vegetation.

[0002]

2. Description of the Related Art Conventionally, a vegetation soil in which frame-shaped precast concrete vegetation blocks having openings formed through the front and back sides are laid side by side on a slope and fertilizer is mixed in the openings of these vegetation blocks. There is known a sloped green retaining wall that is filled with lime to grow plants such as lawns.

[0003]

The conventional sloped green retaining wall has a low water retention property, impairs the growth of plants in the dry season, and gradually loses the effect of fertilizer after a few years. However, there is a problem that it is difficult to grow a plant for a long period of time. In addition, the surface of the slope is covered with vegetation soil, and the vegetation soil is exposed on the front side, so it is impossible to prevent slope erosion and soil runoff by rainwater etc. until the roots of the plant grow. was there.

The present invention has been made in view of such conventional problems.
The present invention aims to provide a sloped green retaining wall that allows plants to grow for a long period of time and that can prevent erosion of slopes and runoff of soil.

[0005]

The features of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose are as follows.
A vegetation block made of precast concrete that has a frame part and an opening that penetrates inside and outside is formed inside it.
In a sloped green retaining wall in which the openings of the vegetation blocks are laid side by side and vegetated, the vegetation blocks have a bottom plate having openings opened through the front and back sides and a front side of the bottom plate. It consists of a narrow frame part provided integrally,
The vegetation base material, which is mainly made of organic fiber material and is hardened in a porous form and mixed with the fertilizer, is contained so as to close the opening of the vegetation block.

The bottom plate of the vegetation block may be filled with vegetation soil, and the vegetation base material may be housed in the opening inside the frame of the vegetation block so as to cover the bottom plate and the vegetation soil. It is more preferable that a fixing hole is formed in the bottom plate of the vegetation block, and that the wire anchor fixed to the slope is inserted into the fixing hole.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an example of an embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, 10 is a vegetation block made of precast concrete.
As shown in FIGS. 2 and 3, has a square bottom plate 16, and an opening 19 is formed in the center of the bottom plate 16 so as to penetrate the front and back. A narrow frame portion 11 is integrally provided on the front side of the bottom plate 16, and the opening 14 inside the frame portion 11 is formed large. Also, the bottom plate 1
The fixing holes 17 and 17 are formed in the sheet 6 by penetrating both sides.

Further, in FIG. 1, reference numeral 100 denotes a slope such as embankment and cut, a precast concrete foundation 20 is installed on the slope, and the vegetation blocks 10, 10 are provided on the surface of the slope 100. …… are arranged vertically and horizontally so that their side surfaces contact each other, and wire rod anchors (reinforcing bar anchors, etc.)
It is laid via 70, 70 ... That is, each vegetation block 10 is fixed to the slope 100 such that the wire anchor 70 is inserted into the fixing hole 17 of the bottom plate 16. Therefore, the wire rod anchors 70, 70 ...
Firmly bite into the ground of the vegetation block 10,10
...... is securely fixed, so sufficient stability is secured.

The opening 19 of the bottom plate 16 of each vegetation block 10 is filled with vegetation soil 90, and the frame 11
A vegetation base material 40 is accommodated in the opening 14 inside the so as to close the opening 14 and cover the vegetation soil 90 and the bottom plate 16. The vegetation base material 40 is mainly composed of organic fiber materials such as plant stems and twigs, mixed with organic / inorganic fertilizer components and plant seeds, and solidified into a porous rectangular parallelepiped by a binder. is there.

Therefore, the surface of the slope 100 is covered with the bottom plate 17 made of concrete, and the opening 19 of the bottom plate 17 is covered with the vegetation base material 40 made of organic fiber material through the vegetation soil 90. Therefore, even if the root of the plant is in an ungrown state, it is possible to preferably prevent the slope 100 from being eroded by rainwater or the like. Also, vegetation soil 9
Since 0 is covered with the vegetation base material 40, soil runoff can be preferably prevented. On the other hand, the concrete frame 11
The area where vegetation is applied (opening 1
The area of 4) can be increased.

The stems and leaves of the plant extend from the vegetation base material 40 to the front side of the vegetation block 10, and the roots of the plant extend sufficiently to the vegetation soil 90 and further to the slope 100 on the back side of the vegetation block 10. In addition, since the fertilizer component is continuously supplied while the vegetation base material 40 is decomposed, the plant can be appropriately grown for a long period of time. In addition, due to the high water retention of the vegetation base material 40, it is possible to reduce growth disorders during the dry season. In addition, erosion of the slope 100 and runoff of soil can be prevented more favorably by the growth of plant roots.

[0013]

Industrial Applicability As described above, the slope green retaining wall according to the present invention is made of organic fiber material as a main component and hardened in a porous form, and the vegetation base material mixed with the fertilizer is contained in the vegetation block. As a result, since the fertilizer component is continuously supplied from the vegetation base material for a long period of time, the plant can be suitably grown for a long period of time. Then, using a vegetation block consisting of a bottom plate having openings opened through the front and back and a narrow frame portion integrally provided on the front side, the vegetation base is closed so as to close the opening of the vegetation block. By storing the timber, the surface of the slope is covered with the bottom plate of the vegetation block and the vegetation base material, and the erosion of the slope can be suitably prevented, and the area of the portion where vegetation is applied can be increased. . Further, by filling the opening of the bottom plate of the vegetation block with vegetation soil, and by housing the vegetation base material in the opening inside the frame of the vegetation block so as to cover the bottom plate and the vegetation soil,
Soil runoff can be preferably prevented.

Further, a fixing hole is formed in the bottom plate of the vegetation block, and a wire anchor fixed to the slope is inserted through the fixing hole to keep the vegetation block on the slope while maintaining a large area of the portion to be vegetated. It can be securely fixed to the to secure sufficient stability.
