Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a green concrete block and a slope protection wall for facilitating the propagation of plants and achieving the purpose of revetment.

[0002]

2. Description of the Related Art Conventionally, as vegetation-based seawalls, an erosion prevention sheet, a connecting material such as a stone, or a porous concrete for greening is known. There is also a proposal of a vegetation method frame device in which a vegetation packing clay is filled in a concrete method frame (JP-A-11-50477).

[0003]

Although the conventional slope protection wall has been improved by the transition to the vegetation-based revetment as described above, it has been found that the conventional slope protection wall is not suitable for places where continuous external force is applied (for example, river revetment). It is an issue for the future to have a recovery function.

That is, in rivers, erosion, movement, and accumulation of sediment are constantly occurring. Among them, a place where sediment is deposited, and a place where a natural riverbank due to vegetation is required in a place where the external force of the flood or the possibility of the flood is small, are as follows. However, it is difficult to establish vegetation more stably in places where hard seawalls are required because of the location where erosion occurs, such as a water collision part. Therefore, it is necessary to consider the loss of vegetation in natural revetments to some extent beforehand, and it is important for the management and maintenance of the revetment to provide natural resilience to the eroded areas.

[0005] Therefore, there has been a demand for the development of technology for maintaining the vegetation base even after the water has been washed away, and it has been recommended to use porous concrete.

In addition to the self-renewal function, it is effective to provide a mechanism for accumulating sediment on the front of the revetment. The point of activation is still insufficient, and has been regarded as one of the issues in technology development.

[0007] The disclosed invention is extremely effective in promoting durability and vegetation on slopes on land,
It is still inadequate for revetment of rivers (particularly those exposed to water currents).

[0008]

SUMMARY OF THE INVENTION The present invention relates to the characteristics of porous concrete (which can be vegetated and has a predetermined strength).
Furthermore, the conventional problem was solved by using a shell fossil, a zeolite, and a sulfate band having a function of activating a plant and improving water quality and the like.

That is, the present invention is a greening concrete block characterized in that a mixture of a sulfuric acid band, a shell fossil powder and a zeolite powder is coated on the surface of a porous concrete block. A greening concrete block characterized by using appropriate amounts of powder and zeolite powder.

[0010] A green concrete block characterized by providing a porous concrete layer outside a block made of a sulfuric acid band, shell fossil powder and zeolite powder.
The ratio of shell fossil powder and zeolite powder is 10% to 8%.
0% (mass).

Next, the invention of a slope protection wall is a river protection wall or other slope protection wall constructed by the greening concrete block.

In the above invention, the reason why the amount of the shell fossils and other materials to the porous concrete is 10% (by mass) or more is that when these materials are less than 10%, the specific effects of the shell fossils and the like are reduced. . Naturally, even if 5% is used, it is naturally superior to the case where it is not used.
In particular, when the porous concrete block is large, it is sufficiently effective when shell fossils and the like are layered only on the surface side (vegetation side). Therefore, the amount used depends on the vegetation conditions. For example, when porcelain is provided with cavities at predetermined intervals (for example, 50 cm) at predetermined intervals (for example, 50 cm) and shell fossils or the like are buried in the cavities and vegetated, irrespective of the amount of the porous concrete, a sufficient amount of shellfish for vegetation is obtained. Since it is sufficient to use fossils or the like, even if it is 5% or less, the objective may be sufficiently achieved.

When the content of the shell fossils exceeds 80%, the strength of the whole decreases, and it is often unsuitable for river bank protection.
For example, for only slope protection (on land), even if it exceeds 90%, it can be fully utilized. For example, it is not washed by water like a river, but during vegetation until the plants take root in sufficient strength. In such a case,
Porous concrete for reinforcement may be buried in a block of shell fossils or the like.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has improved porous concrete which has strength of slope protection and is suitable for vegetation.
It is a greening concrete block and a slope protection wall for the purpose of supporting vegetation and purifying and activating water quality.

Therefore, a green concrete block is formed by layering a mixture of shell fossil, zeolite and a sulfate band (hereinafter referred to as shell fossil) on the surface of porous concrete.

Further, it is a greening concrete block formed using a material obtained by mixing a material of porous concrete and a fossil shellfish.

A slope protection wall constructed by the green concrete blocks.

The ratio of porous concrete to shell fossils in the above is from 10% to 80% as a tentative standard, but since it aims at promoting vegetation and maintaining strength, there is a great difference depending on the structure used. The material ratio is not limited.
