钻孔灌注桩在工程施工中的控制要点

Control points of bored pile in engineering construction

结合工程实例,介绍了钻孔灌注桩施工准备工作,从桩位、泥浆、钻速等方面,阐述了成孔施工阶段的操作要点,并提出了钢筋笼与混凝土浇筑的质控措施,有效保证了钻孔灌注桩的成桩质量。

Combining with engineering examples, the paper introduces bored pile construction preparation procedures. Starting from aspects of pile location, slurry and drilling speed, it describes operation points of hole-forming construction phase, and puts forward steel cage and concrete grouting quality control measures, which effectively guarantees pile forming quality of the bored pile.
