Combined arrangement method for reservoir release structures under pumped storage power station
A combined arrangement method for reservoir release structures under a pumped storage power station comprises the steps that a diversion tunnel, a blow-off pipe and a vertical shaft spillway tunnel are arranged, the axes of the diversion tunnel, the blow-off pipe and the vertical shaft spillway tunnel are arranged in a crossed mode on the plane and do not interfere with one another, the blow-off pipe is communicated with the vertical shaft spillway tunnel, and the included angle between the axis of the blow-off pipe and the axis of the vertical shaft spillway tunnel is set according to terrain conditions; the diversion tunnel and the vertical shaft flood discharge tunnel are communicated and share a water recession tunnel section and an outlet section, the included angle between the axes of the diversion tunnel and the vertical shaft flood discharge tunnel is not larger than 60 degrees, the blow-off pipe comprises a blow-off pipe inlet section, a pipe body section and a blow-off pipe outlet section which are sequentially communicated, a steel gate is arranged at the top of the blow-off pipe inlet section and provided with a base, and the pipe body section is horizontally arranged at the bottom of the base. A blow-off pipe outlet section is arranged behind the blow-off pipe and communicated with the vertical shaft flood discharge tunnel; the arrangement is flexible, independent operation is achieved, and the problems that according to an existing lower reservoir release structure combination arrangement technology, the size of an inlet structure is too large, the reconstruction project amount after gate closing of a diversion tunnel is large, the construction period is short, and the combination part is difficult to construct are solved.
抽水蓄能电站下水库泄水建筑物联合布置方法，包括设置导流洞、放水管和竖井泄洪洞，导流洞、放水管和竖井泄洪洞的轴线在平面上交叉布置，互不干扰，放水管与竖井泄洪洞连通，且放水管轴线与竖井泄洪洞轴线夹角根据地形情况设置，导流洞与竖井泄洪洞连通共用退水隧洞段和出口段，且两洞轴线夹角不大于60°，放水管包括依次连通的放水管进口段、管身段和放水管出口段，放水管进口段顶部设置钢闸门，钢闸门设置基座，管身段水平布设在基座的底部，其后设置有放水管出口段连通竖井泄洪洞；本发明布置灵活，独立作业，解决了现有下水库泄水建筑物结合布置技术，进口结构体型尺寸过大，导流洞下闸后改建工程量大、工期紧张，结合部位施工困难等问题。
