CFG桩施工中常见问题及处理方法

Problems existed in construction of CFG pile and treatment methods

通过对CFG桩施工的认识和复合地层的受力原理分析 ,论述了施工中常遇到的问题 ,如堵管、窜孔、断桩、缩桩、扩径、桩体不垂直和桩体存气等 ,并分析了问题形成的原因及控制方法 ,提高了桩身质量。

Based on the loading mechanics analysis of CFG pile and composite foundation the problems encountered in construction such as pipe plugging, broken pile, pile shrink and existed gas in pile and their controlling methods are discussed. Those measures enhance the pile's quality.
