Description

[Detailed description of the invention] This invention relates to a concrete block that provides a habitat for fish in an irrigation canal using an assembled concrete block fence groove.

As shown in Figs. 3 and 5, the above-mentioned irrigation canal using the assembled fence groove is constructed from a slightly inclined concrete pillar 1 and a pillow material 2 on the bottom to a horizontally long concrete wall plate 3 between a certain piece of equipment a. Alternatively, the side edges of the wall plate 4, which has both sides of the wall plate 3 bent into an L-shape, are placed against the back of the pillar 1 and filled with earth and sand. It is constructed in the same way, and concrete is poured between both side walls at the same level as the surface of the pillow material 2 to form an irrigation canal using an assembled fence groove.

As this facility became more popular, it became desirable for river fish to live in the irrigation canals, similar to earthen banks.

Originally, the irrigation canals mentioned above were for agricultural canals and small river canals, so the inner circumferential surface was made as smooth as possible so as not to impede the flow velocity, and no consideration was given to habitats (including spawning) for river fish. There wasn't.

Therefore, this invention is an attempt to create a place suitable for fish habitat without sacrificing the essence of the above-mentioned assembled fence groove.

To explain the embodiment from FIG. 1, the unit b is made of concrete in the shape of an inverted U, and each end is connected to the pillow material 2 of the adjacent fence material a built at a predetermined interval. The width W of the cavity 5 inside the column 1 is larger than the thickness d of the column 1, and a difference S of the width W and the thickness d is left at both ends. A notch 6 with a length that accommodates one half of the width W of the hole is provided, and a through hole 8 communicating with the cavity 5 is provided in the side wall 7 on the side of the notch 6. .

To explain the second embodiment with reference to FIG. 2, the unit b' is made of concrete and has an inverted U shape, its length is the length between the pillars 1 at a predetermined interval, and its width is the thickness d of the pillars 1 or The thickness of the wall plate 3 is added to the thickness of the wall plate 3, and a through hole 8 is similarly provided.

The use of the first unit b of this embodiment will be explained with reference to FIGS. 3 and 4. Notches 6 are formed in the short pillow material 2 on the back side of the pillars 1 of adjacent fence materials a built at predetermined intervals. Both ends are placed facing the pillar 1, both ends are positioned at 1/62 of the width of the pillow material 2, and the notch part 6 is fitted from the back side of the pillar 1.

The next fence material a installed in the same line and the next fence material a are combined in the same way.

Then, while building the wall board 3 horizontally on the single body b, it is backfilled with earth and sand.

In this way, both ends of the unit b fit into the installed pillar 1 and are fixed by the backfilling soil.

Then, the difference width S of the cavity 5 formed on the back surface of the pillar 1 is a single unit b
The width of the passage that communicates with each other becomes a tunnel with a lid and left and right side walls.

Therefore, water or fish that entered through the through hole 8 of the unit b can exit through the through hole 8 of the other unit b.

The use of the second unit b' of the embodiment will be explained with reference to FIG. 5. The wall board 4 is erected horizontally on the unit b' inserted between the pillars 1, and backfilled with earth and sand.

In this way, it is fixed by a large number of wall plates 4 and backfilling earth pressure.

Water and fish can enter and exit through the through hole 8 of the same unit b'.

In the above usage example, instead of wall plate 3, wall plate 4 can be used on unit b, and in place of wall plate 4, wall plate 3 can be used on unit b'.

In order to create an environment that improves the habitat and spawning conditions for fish, it is recommended to insert pebbles or the like into the cavity 5.

As mentioned above, this design is suitable for the characteristics of fish, as they can move inside and outside the cavity 5 regardless of the strength of the water current, are not washed away during floods, can take food that occurs in the cavity 5, and can spawn and reproduce. It meets the social demands mentioned in the title without impairing the function of the fence groove.
