摘要
江苏溧阳抽水蓄能电站上水库全库底采用HDPE土工膜防渗,土工膜防渗面积达25.4万m^2,底部基础分开挖区和回填区,其中最大回填高度为70 m,土工膜与趾板、进出水口、交通桥等结构物连接部位较多,根据工程的实际情况,从土工膜施工程序、施工方法、安全和质量控制等方面进行了总结,可供其它类似工程参考借鉴。
Impervious HDPE geomembranes are used in whole bottom of upper reservoir at Liyang pumped storage power station in Jiangsu Province. Geomembrane seepage control area is 254000 m2. Bottom foundation is divided into excavation area and backfill area with maximum backfill height 70 m. The geomembranes are connected with toe slabs,inlets and outlets,and traffic bridges in many places. Based on actual conditions of project,geomembrane construction sequences,safety and quality control are summarized in this paper to provide references to other similar projects.
