摘要
本文介绍了冲抓套井回填黏土技术在某水库大坝防渗加固中的施工方法和质量控制措施,并通过防渗墙体填土的压实质量、渗透系数的检测和蓄水后大坝防渗的效果观测,对该项技术的应用情况进行了分析评价。
In the paper, construction method and quality control measures of impact-grab well clay back-filling technology in dam anti-seepage reinforcement of one reservoir are introduced. Application condition of the technique is analyzed and evaluated through testing compaction quality and seepage coefficient of anti-seepage wall soil filling, and observing dam anti-seepage effect after water accumulation.
