Fishway structure with fish passing and ecological discharging functions and construction method of fishway structure
The invention discloses a fishway structure with fish passing and ecological discharging functions and a construction method of the fishway structure, and relates to the technical field of fish passing facilities in water conservancy and hydropower engineering.The upstream side of a barrage is provided with a water diversion channel which is arranged along the axis of the barrage and used for intercepting and taking water, and the two sides of a bottom plate of the water diversion channel are divided into the high side and the low side; the fishway is arranged at the position, close to the shore, of the high side of a bottom plate of the water diversion channel and penetrates through the water diversion channel and the barrage, the fishway is provided with a fishway inlet and a fishway outlet, the fishway inlet is formed in the toe of the barrage, the fishway outlet is formed in the upstream side of the water diversion channel by a certain distance, and the fishway is arranged in a back-bending shape. The downstream of the barrage has ecological flow discharged through the fishway structure throughout the year, and downstream migratory fishes can backtrack to the upstream through the fishway, so that the living environment of the fishes is improved; and meanwhile, the arranged fishway structure does not affect the structural stability of the barrage and does not affect the generating capacity of the small hydropower project.
本发明公开了一种兼顾过鱼和生态泄放功能的鱼道结构及其施工方法,涉及水利水电工程中过鱼设施技术领域,拦河坝上游侧具有沿坝轴线布置的截流取水的引水渠道,引水渠道底板两岸分为高侧和低侧,水流在低侧汇聚后接引至发电厂房,鱼道设置在引水渠道底板高侧靠岸位置,穿过引水渠道和拦河坝,鱼道具有鱼道进口和鱼道出口,鱼道进口设置在拦河坝坝趾处,鱼道出口设置在引水渠道上游侧一定距离,鱼道采用回弯形布置。拦河坝下游常年有通过鱼道结构下泄的生态流量,且下游洄游鱼类可以通过鱼道上溯至上游,改善了鱼类的生存环境;同时,设置的鱼道结构不影响拦河坝的结构稳定,且不会影响小水电工程的发电量。
