Reciprocating type side-wall-sharing fishway structure
The invention relates to the technical field of fishways, and discloses a reciprocating type common-side-wall fishway structure which comprises a fishway body, a zigzag fishway groove which is folded back and forth is formed in the fishway body, a downstream fish inlet is formed in the downstream end of the fishway groove, and the downstream fish inlet is used for feeding fish and discharging water. An upstream fish outlet is formed in the upstream end of the fishway groove and used for water inflow and fish outflow, and the gradient of the fishway groove is gradually increased from the downstream fish inlet to the upstream fish outlet. Upstream water enters the fishway groove through the upstream fish outlet and then is discharged from the downstream fish inlet through the fishway groove, and downstream fish traces upwards through the downstream fish inlet and reaches the upstream from the upstream fish outlet through the fishway groove, so that upstream tracing of the fish is completed, the structure is simple, meanwhile, the fishway engineering construction cost is low, the occupied area of the fishway is reduced, and the space of the fishway is saved. And different measures are respectively adopted from the upper, middle and lower height parts of the groove body to reduce the flow velocity, so that the survival environment of fishes in the fishway is improved.
本发明涉及鱼道技术领域，且公开了一种往复式共侧墙鱼道结构，包括鱼道主体，所述鱼道主体内形成有呈之字形往复回折的鱼道槽，鱼道槽位于下游的一端开设有下游进鱼口，下游进鱼口用于进鱼和出水，鱼道槽位于上游的一端开设有上游出鱼口，上游出鱼口用于进水和出鱼，由下游进鱼口至上游出鱼口鱼道槽的坡度逐渐抬高。上游水通过上游出鱼口进入鱼道槽，然后经过鱼道槽从下游进鱼口排出，下游鱼通过下游进鱼口上溯，然而经由鱼道槽从上游出鱼口抵达上游，从而完成鱼类的上溯，结构简单的同时，鱼道工程建设成本也较低，缩小了鱼道占地面积，减小了开挖结构工程量，从槽身上、中、下高度部分分别采用不同措施减小流速、改善鱼道鱼类生存环境。
