摘要
针对燕山水库防渗墙下坝基渗漏问题,在防渗墙体预埋灌浆管并对坝基采取自上而下循环式帷幕灌浆法施工,介绍了灌浆设计及墙体预埋管的施工方法,总结了帷幕灌浆中的施工方法和灌浆检查结果。结果表明灌浆效果很好,达到了防渗补强目的,可为同类工程施工提供参考。
Aiming at the dam seepage of Yanshan Reservoir, the diaphragm wall was constructed by adopting the topdown circulating grouting method with grout pipe which was pre-buried in wall body. The curtain grouting construction technique in concrete diaphragm wall was introduced, and the reasonable parameters were proposed. Evaluating effects of curtain grouting showed that this technique can meet design requirement and can be applied to similar projects.
