旋挖钻孔灌注桩在泥质粉砂岩地区施工实践

Construction Practice of Revolving Bore Grouting Pile in Argillaceous Siltstone Area

摘要:

通过旋挖钻孔灌注桩在广西某大型电厂泥质粉砂岩地区的实际应用，分析了旋挖钻孔灌注桩与冲孔灌注桩相比具有的优势和特点，并针对施工中遇到的实际问题提出了相应的处理措施，可为今后该地区类似场地钻孔灌注桩施工提供一定参考。

Abstract:

By the practical application of revolving bore grouting pile in a large power plant in argillaceous siltstone area of Guangxi, and compared with impact bore grouting pile, the advantages and features of revolving bore grouting pile are analyzed. Some appropriate measures for the difficult problems in construction are proposed, which could be reference to the bore grouting pile project in similar geological conditions.
