摘要
通过对断桩,扩大头体积不足,桩身缩颈,管内进水或进浆,地面隆起,钢筋笼上浮,桩身出现离析、夹泥、夹砂等问题产生的原因进行分析,并提出解决方案,希望对解决夯扩桩常见的质量问题提供参考借鉴。
By analyzing the causes of pile breaking, insufficient volume of enlarged head,necking of pile body,water or slurry in pipe,ground uplift,floating of reinforcement cage,segregation of pile body,mud inclusion and sand inclusion. This paper puts forward solutions,hoping to provide reference for solving common quality problems of rammed expanded pile.
