复杂地质冲孔灌注桩施工技术

Punching pile construction technology for complicated geological condition

本文通过工程实例解决了复杂地质(如旧桩、孤石、含砂率、孔深)的冲孔灌注桩施工难题,采取4项施工技术,有效控制了冲孔灌注桩施工质量,取得了良好的技术、经济、环保和社会效益。

Through an engineering example, the difficulty of the punching pile construction on complicated geological conditions such as ex- isting pile, boulder, sand ratio and the hole depth was solved. Four construction technologies were applied to effectively control the quality of punching cast - in - place pile and achieved good technical, economic, environmental and social benefits.
