Document Type and Number:
Japanese Patent JP3733426
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To create an area, wherein aquatic life can live, in a sloping artificial canal by utilizing the forces of nature.
SOLUTION: This artificial canal 2 is equipped with a bottom section 4 of natural deposits and side wall sections 3A and 3B to which revetment is applied by using concrete. Cross members 6 for connecting both the wall sections 3A and 3B together are provided in the artificial canal 2 at a prescribed interval D1; notched parts 5A and 5B, which are formed in such a manner as to be different in width-direction position from the adjacent cross members 6 and 6, are provided in the upper parts of the cross members 6; and a swell-head board 8 is inserted into the notched parts 5A and 5B. The notched parts 5A and 5B and the cross members 6 bring about the creation of a water area S1 wherein a stream of water flows downward and a water area S2 wherein the stream of the water flows horizontally; a pool 12 is formed in the water area S1 by scouring; and a shoal 11 is formed in the water area S2 by depositing sediment.
