Abstract
The present disclosure discloses a buffering fishway suitable for emergent flood discharge with reduction in damage and a buffering method thereof. The buffering fishway includes a fishway body, wherein a migration passage is arranged inside the fishway body, one end of which is rotationally connected with a fixing base, and the other end of which is rotationally connected with a counterweighting floating dock, and a plurality of buffering plates capable of swinging are hinged inside the migration passage, furthermore, the present disclosure also provides a buffering method corresponding to it. The present disclosure effectively reduces the potential energy of the flood and weakens the impact force on the fish. Therefore, the gate dam having this design effectively avoids the fish in the fishway from being fiercely impacted by the flood and easily resulting in damage during discharging flood, having a high protective effect on the fish.
