Water inlet and outlet arrangement structure of lower reservoir of pumped storage power station and construction method of water inlet and outlet arrangement structure
The invention relates to a pumped storage power station lower reservoir water inlet and outlet arrangement structure and a construction method thereof, and belongs to the technical field of pumped storage power station lower reservoir design. The arrangement structure for the water inlet and outlet of the lower reservoir of the pumped storage power station comprises a natural river channel, the water inlet and outlet of the lower reservoir and a water collecting groove formed by excavating a side slope, the water collecting groove is provided with a side slope supporting structure, and the water inlet and outlet of the lower reservoir is arranged in the water collecting groove. The side, close to the natural river channel, of the water collecting groove is provided with an overflowing channel communicated with the natural river channel, a plurality of underwater cast-in-place piles are fixedly arranged in the overflowing channel, the underwater cast-in-place piles define a vertical sliding way, a reinforced concrete cushion layer is arranged at the bottom of the vertical sliding way, and a detachable and replaceable filter element is installed in the vertical sliding way; a desilting pipeline is connected to the end, close to the downstream of the natural river channel, of the bottom of the water collecting groove and communicates with the downstream of the natural river channel, and a gate is arranged at the end, close to the water collecting groove, of the desilting pipeline.
本发明涉及一种抽水蓄能电站下水库进出水口布置结构及其施工方法，属于抽水蓄能电站下水库设计技术领域。本发明所述的抽水蓄能电站下水库进出水口布置结构，包括天然河道、下水库进出水口以及在边坡开挖形成的集水凹槽，集水凹槽配设有边坡支护结构，下水库进出水口设置于集水凹槽内，集水凹槽靠近天然河道的一侧具有与天然河道相连通的过流通道，过流通道内固定设置有多根水下灌注桩，水下灌注桩围合形成竖向滑道，竖向滑道的底部设置有加筋混凝土垫层，竖向滑道内安装有可拆卸更换的滤芯；集水凹槽的底部在靠近天然河道下游的一端连接有排沙管道，排沙管道与天然河道的下游相连通，排沙管道靠近集水凹槽的一端设置有闸门。
