钻孔灌注桩施工质量的监理控制

Supervision and Control of Construction Quality of Borehole Cast-in-place Concrete Pile

钻孔灌注桩属于隐蔽工程,成桩环节多,施工过程容易出现质量事故,监理人员必须重视施工全过程质量监控。本文就钻孔灌注桩施工准备工作、成孔过程、灌注水下混凝土以及事故处理等环节的质量监理程序和关键点质量控制方法进行讨论和分析,提出了保证钻孔灌注桩施工质量的监控措施。

The borehole cast-in-place concrete pile is a concealed work provided with much piling operation. Because accident is easy to happen during construction operation, the supervisors must pay great attention to the quality control in the whole construction operation. The paper discusses and analyzes the quality supervision procedures and the key-point quality control methods of preparation work, borehole process, cast-in-place of under water concrete and settlement of accident, etc. during the borehole cast-in-place concrete pile construction and puts forward the supervision and control measures of quality assurance of borehole cast-in-place concrete pile construction.
