摘要
结合工程概况,确定采用上部无水地带人工挖孔、下部富水地带机械成孔相结合的施工方法,并对其成孔工艺、清孔及钢筋笼就位、水下混凝土的灌注等施工技术进行了介绍,对复杂地层钻孔灌注桩的施工具有重要的参考意义。
Combined with practical work construction method is adopted,which utilize manual hole digging method in upper part and machine-dug method in under part with rich water.Practical construction technology of hole building, hole cleaning operation,installation of reinforcement cage and grouting of underwater concrete are introduced,which provides good references for bored concrete pile construction under complex geological condition.
