钻孔灌注桩后压浆技术的应用

Application of Latter Grouting to the End of Castin-place Pile

钻孔灌注桩后压浆技术通过向半成品桩体内预埋的高压注浆管压入水泥的方法,使水泥浆对半成品桩桩侧泥皮和桩端沉渣进行固化。该项技术在基础处理方面应用非常广泛,本文结合工程实例,具体分析了钻孔灌注桩后压浆技术的基本原理和施工工艺、压浆质量控制标准以及相关的技术参数,并通过实际工程的应用提出了相关的注意问题。

The latter grouting technology is widely applied in the ground treatment, this article unifies the actual project, and specifically analyzes the basic principle, construction craft, quality control strandard as well as the correlation technical parameter about the end of cast-in-place pile, and raises some related questions through the actual project application.
