摘要
裂隙岩体防渗是抽水蓄能电站建设中需要解决的重要问题。针对微裂隙岩体灌浆处理,提出了一种工程性能优良、可灌性好的纳米硅溶胶注浆材料,以清远抽水蓄能电站为工程依托,针对断层破碎带和微裂隙岩体的防渗处理,提出以水泥基浆液为主、硅溶胶为辅的联合施工技术,检测结果表明,施工后防渗效果满足工程要求。
Anti-seepage of fractured rock is the major issue encountered in the construction of pumped storage power station.Therefore,a kind of nano-silica sol grouting material with excellent engineering performance and good groutability is proposed and utilized to tackle the problem of micro-fractured rock.Subsequently,the combined construction technology relying on Qingyuan Pumped Storage Power Station is put forward by cement-based slurry and silica sol,which aims at conducting the anti-seepage treatment of fault fracture zone and micro-fractured rock.Finally,the test results show that the anti-seepage effect meets the requirements after completion of the project.
