江中桥墩式取水泵站集约化设计

Intensification Design of Pier-type Water Intake Pumping Station in the River

南方某取水泵站整体建在江河中,采用国内罕见的桥墩式取水方式。设计取水量为23.1×10~4m^3/d,为了尽量减少该江中取水构筑物对河流流态、航运等的影响,并降低工程造价,本取水泵站集取水口、格栅池、潜水泵池、变配电间、控制室、值班室等为一体,通过对池体平面及竖向进行集约化设计,设计成一座地下一层、地上二层的建筑物,布置紧凑,占地极省。该江中桥墩式取水泵站运行后,达到了设计水量,水泵和电气自控设备运行稳定可靠,同时泵站稳定性经受住了台风考验,得到一致好评,可为同行业相关设计提供借鉴和参考。

A water intake pumping station in Southern China was built in the river. The rare pier- type water intake was adopted. The design inflow was 23.1 × 104 m3/d. In order to reduce the influence of intake structures on river flow and shipping, the pumping station integrated intake, grille tank, pump tank, power distribution room, control room and duty room. Through the intensive design of the tank body plane and the vertical, the building was designed into one underground layer and two floors above the ground, with advantages of compaction and small land occupation. During the operation of the pum- ping station, the inflow met the design value, the pump, electrical equipment and automatic control e- quipment were stable and reliable. The stability of the pumping station has withstood the test of typhoon, and received consentaneous reputation. This project could be used as a reference for similar projects.
