摘要
根据柬埔寨甘再水电站反调节上、下游土石围堰防渗工程地层的特殊性,并结合红枫、彭水、银盘等水电站围堰防渗工程施工成功的经验,采用了以膏浆灌浆为主,并以静压灌浆为辅的处理方法,使围堰防渗取得了成功,进一步证实了膏状浆液水泥灌浆在特殊地层中进行防渗的可行性。
According to the strata characteristics of the seepage control works for the upstream and downstream earth - rock cofferdams for regulation of Kamchay hydropower project in Cambodia, and based on the successful experience in construction of cofferdam seepage control works for Hongfeng, Penshui and Yipan hydropower stations, the method of mainly using cement paste grouting and supported by static pressure grouting is successfully applied for the cofferdam seepage control of this project, which further proves the feasibility of cement paste grouting for seepage control of special strata.
