Abstract:
PROBLEM TO BE SOLVED: To provide a highly workable fishway installed on a riverbed that allows a fish and other aquatic lives to ascend even when a water amount is small.SOLUTION: A fishway installed on a riverbed includes: raising parts 3, 4 fixed on a riverbed 6a on a downstream side of a weir 11 at a set interval, with a height increasing gradually in a stepwise state toward the weir 11; a water storage part 2 fixed on the rising parts; and a slope part 5 connected to an outlet 2a of the water storage part 2 tiltably in a vertical direction with a hinge 9, to be spread over the water storage part 2 on the downstream side or landed on the riverbed 6b. A periphery of the hinge 9 at a lower end of the outlet 2a on the downstream side is formed in an R-shape form, for facilitating tilting of the slope part 5 and expanding a range of the tilting.SELECTED DRAWING: Figure 1
