深圳抽水蓄能电站地下厂房排水方案设计探讨

深圳抽水蓄能电站安装高程为-5.00 m,集水廊道底板高程为-19.5 m,均在海平面以下,不具备自流排水的条件,因此地下厂房场内排水只能通过水泵动力排水。深蓄电站下库为一级饮用水源,对水质要求很高,通过比较分析,推荐采用清污分排的排水方案,避免了厂房排水对下库水体污染,同时达到了水资源的有效回收利用的效果,符合节能环保的设计理念,对同类型地下工程的排水设计具有参考价值。

Drainage Design of Underground Power House of Shenzhen Pumped-Storage Power Station

In the underground power house of Shenzhen Pumped-Storage Power station, with the installation elevation of -5.00 m, and the ground elevation of water collection gallery of -19. 50m, which are both under the sea level, so there is no condition to drain the water by gravity, and the water just can be pumped away by water pump. The lower reservoir of Shenzhen Pumped-Storage Power station is the first grade drinking water source, with high requirement of its water quality. Through comparative analysis, the scheme of draining the clean water and wastewater separately is recommended, which can avoid the wastewater pollute the water of lower reservoir, and also recycle the clean water. And it matches the energy-conserving and environment-protective philosophy, and offers some experience for other similar underground proiect drainage design.
