质量控制点是土木工程施工中对质量进行事前控制的常用方法。本文在钻孔灌注桩施工中,通过事前对其过程进行分析,确定其关键工序和薄弱环节并设置质量控制点,提出了保证施工质量应采取的预控措施。通过质量预控,灌注桩的质量全部满足工程桩的要求,表明质量控制点的设置是准确的,质量预控措施是有效的。 Quality control point is a common method of quality control in civil engineering construction. In the construction of cast-in-place bored pile, it analyzes its process in advance, determines its key processes and weak links and sets up quality control points, and puts forward the pre-control measures that should be taken to ensure the construction quality. Through the quality control, the quality of bored piles all meet the requirements of engineering piles, indicating that the quality control points set is accurate, quality control measures are effective.
