摘要
横泉水库工程地质条件复杂,风化岩层上存在厚度为16～30 m的覆盖层,覆盖层由土层和砂卵石组成。介绍了深厚覆盖层帷幕灌浆施工技术。从灌浆成果、检查孔压水试验、岩芯采取情况分析,灌浆效果明显,达到了预期目的。为深厚覆盖层风化基岩帷幕灌浆积累了经验,可供类似工程帷幕灌浆施工时参考。
Hengquan reservoir has complicated engineering geological conditions, the 16- 30 m thick overburden consisting of soil and sand gravel is on the weathered rock layer. This paper describes the construction technology for curtain grouting of the deep overburden. According to analysis of grouting results, water pressure test to inspection holes and core sampling, the grouting effect is remarkable, and the expected targets have been reached, which accumulates experience for curtain grouting of weathered bedrocks in deep overburden, and provides reference for curtain grouting of similar projects.
