Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite concrete revetment characterized in that, for example, it revets a slope such as a river or a coast, and at the same time, plants are planted on the revetment surface with the passage of time. Is.

[0002]

2. Description of the Related Art Conventional concrete blocks laid on conventional rivers, coasts, etc. evenly cover the revetment surface and block the infiltration of running water to the slope by the concrete block to prevent excavation of the slope. It was a seawall.

[0003]

In the revetment of a concrete block having the above-mentioned structure, the surface of the concrete block is manufactured relatively densely, so that the earth and sand flowing by the slow flowing water will not flow. Although it temporarily adheres to the surface of the concrete block, it will be washed away by sudden running water, and the surface of the concrete block will always expose the skin of the concrete, and the soil will stagnate on the surface. However, there was an inconvenience that the soil could not make plants grow.

[0004]

Therefore, the present invention has been proposed in order to eliminate the above-mentioned inconvenience, and its constitution is that a normal concrete layer is provided on the surface of the slope and a porous concrete layer is provided above it. By forming a hollow part near the boundary of the overlapped part and filling it with soil or water retaining material, growing material, etc. or storing soil or water retaining material, growing material etc. in advance, the porous layer of the upper layer Plants are planted on the surface of the concrete layer to create a natural environment and protect the slope.

[0005]

[Example 1] 1 is a slope, and a normal concrete layer 2 is provided on the surface of the slope 1, and an upper concrete layer is concrete mixed with pumice stone, lightweight aggregate, etc. A porous concrete layer 3 such as concrete with a large number of voids or foamed concrete is formed, and the concrete 2, 3 is constructed by laying a large number of cast-in-place concrete or concrete blocks.

[0006]

[Embodiment 2] A hollow portion 4 is formed in the vicinity of the boundary between the lower ordinary concrete layer 2 and the upper porous concrete layer 3 described in Embodiment 1, and the hollow portion 4 is filled with soil or a water retaining material, a growing agent and the like. It made it possible.

[0007]

[Embodiment 3] A storage unit 5 in which soil, a water retaining material, a growing material, etc. are stored in advance is formed near the boundary between the lower ordinary concrete layer 2 and the upper porous concrete layer 3 described in the first embodiment. is there.

In some cases, the soil 6 may be arranged on the surface of the above-mentioned upper porous concrete layer to a thickness of, for example, about 10 cm. Reference numeral 7 is a base concrete, 8 is a top end concrete, 9 is a backfill material, 10 is a connecting annular portion of reinforcing bars protruding from the corners of the block, 11 is a connecting ring, and 12 is a plant.

[0009]

Since the present invention has the above-mentioned structure, the ordinary concrete broth layer 2 is provided on the slope surface, and the porous concrete layer 3 is formed on the surface by casting in situ, or the ordinary concrete broth layer 3 is formed. Laying a large number of concrete blocks with a porous concrete layer on the surface,
The connecting ring 1 is attached to the connecting annular portion 10 protruding from the corner portion.
1 is inserted and connected to each other for construction. If necessary, the soil layer 6 is formed on the surface thereof.

[00010]

INDUSTRIAL APPLICABILITY According to the present invention, since the surface of the slope 1 is covered with the ordinary concrete 2, it prevents the running water from penetrating into the slope and well serves as a revetment. Since the surface is a porous concrete layer 3, the soil carried by running water often stagnates on the surface and gradually invades inside to be stored, and the soil carries seeds, plants carried by running water. Is rooted and plants are planted on the revetment surface to cover the concrete surface, and insects also inhabit the natural environment by the plants. Also, the vegetated plants eventually wither and become nutrients for next-generation plants, forming an organic circulation cycle on the surface. In addition, the hollow portion 4 is provided near the boundary between the ordinary concrete layer and the porous concrete layer and filled with soil, a water retaining material, a growing material, or the like, or
Providing the storage part 5 in which soil, water retaining material, growing material, etc. are stored in advance near the boundary between the ordinary concrete layer and the porous concrete layer is more effective for growing plants. .
