Abstract

PURPOSE:To permit the inhabilitation of fish by a method in which the bottom or bent portion of a block for constructing a water channel of an L- or U- shaped cross section is recessed to form a chamber wherein fish enters for taking a refuge. CONSTITUTION:A uprising wall 1 is inclined backwards and the lower end of the uprising wall 1 is bent sidewards to a bottom plate 2. The back portion of the bottom plate 2 is recessed to form a chamber 5. Also, a chamber 13 may be provided by expanding the lower both sides of an U-shaped base material 12. The blocks are connectedly set to form a water channel, where these chambers 5 and 13 are formed and fish can enter into the chambers 5 and 13 for taking a refuge or live in the chambers 5 and 13. Even when the inhavilitation of fish is made impossible for a time by repairing river, the natural environment can soon be recovered.

b. Effects and Embodiments of the Invention The embodiments of the present invention will be described in detail with reference to the drawings.
The bottom plate L21 is formed by tilting the wall t1) backward and bending the lower end of the vertical bifurcated wall +11 in the horizontal direction.
) is recessed to form a retaining channel block (4) with a chamber (3), and as shown in Figures 4 to 6, the rising wall +11 and the bottom plate (2) are bent. Another earth retaining waterway block (6) with a chamber (5) is formed by recessing the continuous part diagonally downward, and the lower part of the rising wall (+) is formed as shown in Figures 7 to 9. An earth retaining water channel block (with a bottom plate (1) bent in the backward-inclining direction of the wall +11 that rises in the shape of a letter) and a concave portion connected to the bottom plate (7) to form a chamber (8). 9), and as shown in FIGS.
As a modification, the chamber part (10) is recessed downward from the bottom plate (1) to form another earth retaining waterway block (11), and as shown in Figs. (12) by bulging both sides of the lower part of the chamber (13) (13)
), and the earth retaining water channel block (14) is connected to a normal type U-shaped groove block (+5), and as shown in Figs. 16 and 17. A bolt hole (1'7) through which a connecting bolt (16) is inserted is bored in the side wall forming the chamber (13),
In addition, as shown in Figure 18, in order to increase the amount of water flowing, the earth retaining channel block (1B
) to form.

Effects of the Invention When each earth retaining waterway block is connected to form a waterway, fish can take shelter or live in each chamber, and the natural environment that has become temporarily uninhabitable due to river improvement can be restored. can. In the case of the retaining canal block (4), the chamber (3) projects downward, which prevents the block from sliding forward due to shape resistance on the river bed, and prevents the retaining canal block (6) from sliding forward. In this case, the room (3) is raised but the wall + I]
and the bottom plate i21 to prevent it from falling over and from sliding forward. In the case of the earth retaining waterway block (9), the bottom plate (7) does not stand up.
1) Since it is installed on the backward tilting side, earth pressure can be applied to prevent it from falling over and it can be installed in a stable manner. Since they can be stably arranged in a row and the chambers (10) project downward, their shape resistance can prevent them from sliding out. In the case of earth retaining waterway block (14), the chamber part (+3
)'! The side wall forming f reinforces the strength, and it is easy to construct the C connection by fastening bolts, and in the case of the earth retaining waterway block (18), since there is no side wall in the chamber (13), the water flow m can be increased.
