摘要
在某棚户区改造工程地下室基础的人工挖孔桩,桩为椭圆桩,在施工过程中经桩基声测和钻芯取样检测表明桩身存在质量缺陷,桩中取出的砼呈松散状,石头含量明显不足,离析情况严重。本文通过对该施工过程中人工挖孔桩桩身质量缺陷形成原因进行系统分析,为今后类似工程及出现类似情况时提出改进及处理措施。
in the shanty town of suining second well ditch,the manual digging hole pile is the ellipse pile.The sound measurement of pile foundation and the sampling test of drill core show that there are quality defects in the pile body,concrete is loose,the stone content is obviously insufficient,the segregation is serious.In this paper,a systematic analysis of the causes of the defects in the quality of the pile with manual excavation is c arried out.
