Centralized overflow structure capable of automatically controlling water depth in fishway and construction method
The invention discloses a concentrated overflow structure capable of automatically controlling water depth in a fishway, which comprises the following steps of: according to habits of migratory fishes in a river channel, drawing up suitable water depth h and flow velocity v of the fishes, and correspondingly drawing up a fishway bottom slope i; the lowest normal operation water level and the highest normal operation water level of a reservoir area are defined as H1 and H2, only one fishway outlet is arranged in the reservoir, and the elevation of a bottom plate of the fishway outlet is h lower than H1; the slope of a fishway bottom plate on the downstream side of a fishway outlet is i, the slope is lowered along the axis of the fishway to be above (H2-H1)/i away from the fishway outlet, then a flat-bottom overflow pond is arranged, an overflow pond water outlet is formed in the side wall of the fishway, an overflow structure is arranged in a local area of the fishway, and the water depth and the flow speed in the fishway are automatically adjusted. The fishway is provided with a single outlet to meet the fish upstream requirement, repeated scheduling of gates under the condition of multiple outlets is avoided, and fishway operation and maintenance work is simplified; overflow structures are arranged in a centralized mode, arrangement is relatively easy, and fishway and hub arrangement is prevented from being affected.
本发明公开了一种自动控制鱼道内水深的集中溢流结构，根据河道内洄游鱼类习性，拟定鱼类适宜水深h和流速v，并相应拟定鱼道底坡i；将库区最低、最高正常运行水位定义为H1和H2，仅在库设置一个鱼道出口，鱼道出口底板高程比H1低h；鱼道出口下游侧鱼道底板坡度为i，沿鱼道轴线降坡至距离鱼道出口(H2‑H1)/i以上，然后设置一段平底溢流池，通过在鱼道边墙开设溢流池出水口，通过在鱼道局部区域设置溢流结构，自动调节鱼道内水深及流速，使鱼道布置单一出口就能满足鱼类上溯需求，避免了多出口情况下的各闸门反复调度，简化了鱼道运维工作；溢流结构集中布置，布置相对容易，避免影响鱼道及枢纽布置。
