摘要
结合工程地质概况,通过对地质雷达和超前水平钻探结果的分析,提出采用超前预注浆的加固方案,并从止浆墙的施作、超前预注浆的加固范围、注浆工艺过程等方面阐述了其施工技术,最后对注浆效果进行了检查评估,达到堵水和加强围岩稳定的目的,为今后类似工程的施工提供参考。
Combined with the engineering geology survey, through geological radar and advanced horizontal drilling result analysis, the paper proposes the program of advance grouting strengthening project, and from the slurry prevention wall ap- plied, the slurry grouting reinforcement scope of the advance grouting, grouting construction process, this paper describes the construction technology, and evaluates the grouting effect to strengthen the stability of surrounding rock and water pre- vention purpose, to provide the reference for other similar project construction.
