Abstract

PROBLEM TO BE SOLVED: To enhance a biotic environment by providing legs at the four corners of a bottom face, making the surface and bottom communicate with each other using through holes and making the bottom face surrounded by the legs to be a spaced part. SOLUTION: An almost square block 1 for a riverbed is provided with legs 3 at the four corners of its back face, a space 4 is formed in its bottom face surrounded by the legs 3, an open part 5 that opens to four sides is provided on its side face between the legs 3, and a through hole 6 communicated to the space 4 from the front of the block is formed. Next, the blocks 1 are laid over the riverbed while an ecomat of coconut fibers or the like enclosing seeds or roots of aquatic plants, or boulders or the like are placed in the space 4. In this case, since the space 4 is communicated to the front by the through hole 6, the river water is allowed to enter the space 4, creating an environment in which aquatic insects and plants and the like can live. Since the space 4 is communicated to four sides by the open part 5, the water, insects, and fishes are allowed to freely enter and exit, and the water is purified by bacteria living in the space 4. Therefore, an excellent ecology for creatures to live in can be constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a river, a river, a waterway,
The present invention relates to a riverbed block used for a riverbed such as a pond.

[0002]

2. Description of the Related Art Blocks made of concrete or plastic are laid on riverbeds such as rivers, rivers, waterways, ponds and the like.

[0003]

Recently, in rivers and the like, ecologies for living organisms such as aquatic insects and plants have been emphasized. However, the conventional riverbed block is a simple block, and no consideration has been given to ecology.

[0004] It is an object of the present invention to provide a riverbed block which is excellent in ecologies for living organisms.

[0005]

A first means of the present invention for solving the above-mentioned problems has a substantially square shape, has legs formed at four corners of a bottom surface, and penetrates so that the surface and the bottom surface communicate with each other. A hole is formed, and a bottom surface surrounded by the legs is a space.

A second means of the present invention for solving the above-mentioned problem is characterized in that, in the above-mentioned first means, an ecomat such as a coconut real fiber is provided in the space.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, a rectangular groove 2 is formed on the surface of a substantially square riverbed block 1.
Are formed, and leg portions 3 are formed at four corners on the back surface. Accordingly, the bottom surface surrounded by the four legs 3 forms a space 4, and the side surface between the legs 3 is an open portion 5 opened in four directions. A rectangular through hole 6 is provided in the groove 2 so as to communicate with the space 4 on the bottom surface. Further, on the side surface of the riverbed block 1, a convex portion 7 is formed on one of two opposite sides and a concave portion 8 with which the convex portion 7 is engaged is formed on the side surface of the riverbed block 1 so as to be easily laid on the riverbed. .

[0008] Therefore, an ecomat such as coconut coconut fiber containing aquatic plant seeds and roots in advance is disposed in the space 4 of the riverbed block 1 and spread over the riverbed as shown in FIGS. 2 and 3. A boulder 9 is placed in an arbitrary space 4.

As described above, since the space portion 4 on the back surface communicates with the front surface through the through hole 6, water such as a river can enter the space portion 4. Therefore, the space 4 is a suitable environment in which aqueous insects, plants, and the like can live. In this case, if an ecomat such as coconut palm fiber is provided in the space portion 4, the environment becomes more favorable for the inhabitation of living organisms, and the environment is excellent. Also, since the space 4 of the riverbed block 1 is communicated in all directions by the opening 5, water, insects and fish can travel in all directions. For this reason, the water purification action by the bacteria that inhabit the space portion 4 is also obtained.

The riverbed block 1 may be made of concrete or plastic. The surface may be formed in a cobblestone shape. Further, instead of a square shape, it may be formed in a rectangular shape.

[0011]

According to the present invention, the riverbed block has a substantially square shape, has legs formed at four corners of the bottom surface, and has a through hole formed so that the surface and the bottom surface communicate with each other. Since the enclosed bottom is a space, it has excellent ecological habitat for living things.
