Vertical seam type fishway structure

The utility model provides a vertical seam type fishway structure. The utility model relates to the technical field of migratory fish dam-crossing protection. The problem that fishes migrate in a fishway and pass through an artificial water tank channel of a water gate is solved. The problems that on the low water level side, fishes enter a fishway through attraction and reverse flow of water flow, flow speed is overcome by means of self-power to swim to the high water level side, inland river water flow is gentle, Yangtze river water flow is torrent, water flow is prone to disorder, and fishes are difficult to swim back are mainly considered, and the fishway pier wall is included. A fishway bottom plate is installed in an inner cavity of the fishway pier wall. According to the utility model, a long groove type double-side vertical seam multi-compartment structure is adopted; it is considered that the overall arrangement and body type design of the engineering fishway are excellent, the engineering fishway co
