Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a block for fish hollows.

[Prior Art] Conventionally, this type of device is as follows.

1. Cover the entire area with concrete to preserve the riverbed and slope.

2 Geometric structures such as three-sided concrete walls and vertical drops are used.

[Problems to be solved by the invention] The conventional techniques described above had the following problems.

1. With conventional drop structures, the riverbed is covered with concrete, making it difficult to maintain the ecosystem.

This is due to the impermeability of the riverbed and the decrease in total surface area.

2. Conventional drop structures impose sacrifices on the river environment and landscape.

3 With conventional drop structures, it is difficult to shorten the construction period because concrete is cast on site.

The present application was made in view of the problems of the prior art, and its purpose is to provide a solution to the above-mentioned problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

That is, in the present application, there is a left vertical wall 3 that stands upwardly at the left end of the base portion 2 that is rectangular in the left and right planes, and a left vertical wall 3 that is connected to the upper end of this left vertical wall toward the right. It consists of an upper horizontal wall 4 and a right vertical wall 5 erected upward at the right end of the base part 2,
Moreover, the height of this right vertical wall is lower than the height of the left vertical wall 3, which is a block for a fish hollow.

In this case, the base is divided from the center to the left and right,
It can be configured into a left part and a right part.

Further, a permeation opening configured in a shape such as a planar rectangle can be opened in the base portion.

Furthermore, a rock pattern can be placed on the upper surface of the upper horizontal wall and the upper surface of the right vertical wall.
