Overflow water supplementing type fishway structure suitable for water head fluctuation
The invention discloses an overflow water supplementing type fishway structure suitable for water head fluctuation in the technical field of fishway construction. The overflow water supplementing type fishway structure comprises first side walls, and a fishway is formed between the two first side walls; the second side wall is arranged on the outer side of the first side wall, and a water supplementing channel is formed between the second side wall and the first side wall; the partition plates are arranged in the fishway at intervals and divide the fishway into a plurality of pond chambers which are communicated in sequence; the overflow holes are formed in the first side wall at intervals in the extending direction of the fishway, and the overflow holes communicate with the pond chamber and the water supplementing channel. Water, exceeding the designed waterline, in the fishway overflows into the water supplementing channel through the overflow holes, the water depth in the fishway is gradually reduced, and therefore the phenomenon that the water level in the fishway suddenly drops is avoided, the adaptability of the fishway to the upstream water level change is improved, water in the water supplementing channel flows to the fishway inlet, water supplementing of the fishway inlet can be achieved, and the water supplementing efficiency is improved. The fishway inlet water flow influence range is expanded, and the fish luring effect is improved.
本发明公开了鱼道建筑技术领域的一种适用于水头波动的溢流补水式鱼道结构，包括第一侧墙，两面第一侧墙之间形成鱼道；第二侧墙，第二侧墙设置在第一侧墙的外侧，第二侧墙和第一侧墙之间形成补水通道；隔板，多个隔板间距设置在鱼道内并将鱼道分隔为多个顺序连通的池室；溢流孔，多个溢流孔沿鱼道延伸方向间距设置在第一侧墙上，溢流孔连通池室和补水通道。本发明通过溢流孔将鱼道内部超过设计水线的水体溢流至补水通道内，逐步降低鱼道内部的水深，从而避免鱼道内部发生水位骤降现象，提高鱼道对上游水位变化的适应能力，补水通道的水体流向鱼道进口，可以实现鱼道进口的补水，扩大鱼道进口水流影响范围，进而提高诱鱼效果。
