Fish passage facility for rock-fill dam and manufacturing method of fish passage facility
The invention discloses a fish passage facility for a rock-fill dam and a manufacturing method of the fish passage facility. A concrete fishway foundation is arranged on the downstream part of the rock-fill dam and distributed on the downstream part of the rock-fill dam in a zigzag shape. Supporting blocking parts are arranged on the two sides of the concrete fishway foundation. One-piece box culvert sets are sequentially placed in the concrete fishway foundation. Water inlets of the one-piece box culvert sets are communicated with a reservoir area through a channel. Start and stop facilities are arranged at the water inlets to control the water flow and flow speed of a fishway. At least one branch fish guide channel is arranged at the lower end of the concrete fishway foundation and communicated with the one-piece box culvert sets, and fish luring facilities are arranged in the fish guide channels. The fish passage facility has the beneficial effects of being convenient to construct, wide in application range and convenient to maintain and repair.
