摘要
为保证水电站围堰防渗截水墙达到预期防渗效果,采取案例分析法,简要介绍麻窝水电站工程情况,结合实际确定砌筑截水墙方式及其结构,并提出围堰防渗截水墙袋装黏土水下施工技术应用措施,按照工艺流程,把控施工细节,进而对其施工效果加以验证。研究表明,麻窝水电站工程上游与下游围堰渗水平均值在(8.4×10^(-7)~2.7×10^(-6))cm/s、(4.42×10^(-7)~1.18×10^(-6))cm/s范围内,满足防渗要求,提高了工程质量。
In order to ensure that the seepage prevention and cutoff wall of cofferdam of hydropower station can achieve the expected seepage prevention effect,the project situation of Mawo Hydropower Station is briefly intro-duced by using case analysis,and the mode and structure of masonry cut-off wall are determined according to the ac-tual situation.The application measures of underwater construction technology of bagge clay in cofferdam seepage pre-vention cutoff wall are put forward,and the construction details are controlled according to the process flow,and then the construction effect is verified.The research results show that the average water seepage of the upstream and down-stream cofferdams of the Mawo Hydropower Station project is in the range of(8.4×10^(-7)~2.7×10^(-6))cm/s and(4.42×10^(-7)~1.18×10^(-6))cm/s,which meets the requirements of seepage prevention and improves the quality of the project.
