宜兴抽水蓄能电站上水库工程的排水系统

Drainage system for upper reservoir project of Yixing Pumped Storage Power Station

宜兴抽水蓄能电站上水库全库盆采用钢筋混凝土面板防渗,防渗总面积为18.06万m2。库岸稳定是上水库的主要工程地质问题之一,而影响库岸稳定的主要因素是地下水。工程共设置了5.1 km排水洞及排水廊道,6.5万m排水孔,确保坝体、库岸稳定和降低面板所受的反向水压力。

As the anti-leakage solution,it is used reinforced concrete plate in the whole upper reservoir basin in Yixing Pumped Storage Power Station;and its total area is 180 600 m2.The stability of reservoir banks is one of primary geologic problem,and the groundwater is one of the factors which influences on the stability of reservoir.This project arranges a(5.1 km) waterspout and water drainage gallery,also 65000m drain spout,to make sure the stability of reservoir banks and reduce the reverse water pressure on p...
