水下钻孔灌注桩施工质量控制

Construction quality control of underwater drill-grouting pile

水下钻孔灌注桩已广泛运用于工程建设中，质量控制难度较大。本文从水下钻孔灌注桩施工工艺流程、配合比的设计要求、测量定位控制、成孔过程质量控制、灌注过程中主要环节质量控制等方面介绍了水下钻孔灌注桩的施工质量控制要点。

Characterized by difficult quality control, underwater drill-grouting pile has been widely used in engineering. The paper introduced underwater drill-grouting pile＇s construction quality control point from the following aspects： construction technique flows, the design requirement of mix proportion, measurement orientation control, drill course quality control, pouring course quality control and so on.
