钻孔灌注桩在基坑支护施工中的应用研究

The application research on the bored pile in foundation pit support construction

结合古矿综合服务楼基坑工程的水文地质条件,提出了钻孔灌注桩基坑支护施工方案,并从钻机移位、测量放线、钻孔、清孔等方面,阐述了具体的施工工艺流程与操作要点,最终取得了预期的施工效果。

Combining with hydrology geology conditions of Gushuyuan Mining comprehensive service building foundation pit engineering,this paper proposed the foundation pit construction scheme of bored pile,and from the rig displacement,measurement line,drilling,hole cleaning and other aspects,elaborated the specific construction process and operation key points,finally achieved the expected construction effect.
