摘要
横泉水库工程地质条件复杂,采用帷幕灌浆的方法对风化岩层进行处理以满足水库对防渗要求。风化岩层上为厚度16-30 m的覆盖层,覆盖层由土层和砂卵石层组成。主要介绍了深覆盖层下风化基岩帷幕灌浆试验的钻孔、灌浆施工方法及其灌浆效果分析。为风化基岩帷幕灌浆积累了经验,可供同类大型工程帷幕灌浆时参考。
The geo-engineering condition is complex in Hengquan Reservoir. In order to meet the anti-seepage requirement, curtain grouting method is adopted to deal with the weathered rocks. There is a cover layer of about 16 to 30m in thickness, comprising of soil and sand gravellayers. The technique of drilling and grouting of the curtain grouting in weathered rocks under thick cover layer was introduced in this paper and grouting effects were analyzed.
