在钻孔桩灌注施工过程中,由于钻孔桩的清孔灌注在水下进行,施工中受地质条件、机械设备、技术素质、工艺流程、原材料及混凝土配合比等诸多因素的影响,灌注有时被迫中断,成桩后经检测有时会发现断桩、缩径、夹泥。局部混凝土疏松、蜂窝、气孔等缺陷。在处理这些问题时,如果措施选择不适,操作方法不当,不但费工费钱,而且会影响灌注桩的质量, In the process of perfusion of bored piles, due to the clear hole perfusion of bored piles under water, the construction is affected by many factors such as geological conditions, mechanical equipment, technical quality, technological process, raw material and concrete mix ratio, etc., Was forced to interrupt, into the pile after testing sometimes found broken pile, reduced diameter, mud folder. Local concrete loose, honeycomb, porosity and other defects. In dealing with these problems, if the measures to choose discomfort, improper operation, not only costly work, but also will affect the quality of the pile,
