Fishway structure under large water level variable amplitude
The invention relates to the technical field of fishways, and discloses a fishway structure under large water level amplitude variation, which comprises a dam body, the upstream of the dam body is a reservoir area, the downstream of the dam body is a river channel, and a low fishway and a high fishway are respectively arranged in the reservoir area in a low-high manner and transversely penetrate through the dam body; a downstream fish inlet fishway is arranged at the downstream end of the low fishway; a downstream climbing fishway is arranged at one downstream end of the high fishway; the low-position fishway is evenly provided with low-position fish outlets in the reservoir area, and the high-position fishway is evenly provided with high-position fish outlets in the reservoir area. The low-position fishway and the high-position fishway correspond to frequently-encountered low and high water levels respectively and are responsible for water level amplitude variation of 2-6 meters within the range of the frequently-encountered low and high water levels respectively, the length of the inner section of the fishway reservoir can be effectively shortened, the height of a tank body of the inner section of the fishway reservoir can be effectively reduced, engineering arrangement and tank body structural design are facilitated, operation management is facilitated, and engineering investment is saved. The fishway is novel in design and has the advantage of being capable of effectively shortening the length of the fishway in the garage.
本发明涉及鱼道技术领域，且公开了一种大水位变幅下的鱼道结构，包括坝体，所述坝体的上游是库区，下游是河道，横穿所述坝体在库区内一低一高分别设置有低位鱼道和高位鱼道；所述低位鱼道位于下游的一端设置有下游进鱼鱼道；所述高位鱼道位于下游的一端设置有下游爬升鱼道；所述低位鱼道在库区均匀设置有低位出鱼口，所述高位鱼道在库区均匀设置有高位出鱼口。低位鱼道和高位鱼道各自对应常遇低、高水位，各自负责在常遇低高水位范围内的二～六米水位变幅，能有效缩短鱼道库内段长度，有效降低鱼道库内段槽身高度，有利于工程布置和槽身结构设计，有利于运行管理和节省工程投资。本发明设计新颖，具有能够有效缩短库内鱼道长度的优点。
