在进行CFG桩施工时，会由于场地存在未成层的钙质结核层而引发一些问题，造成了施工困难，影响了施工进度。本文采用汽车钻引孔和步履式长螺旋钻机使用合金钻头相结合的办法，解决了施工困难、进度缓慢的问题，对今后的工程中解决类似问题有一定的借鉴作用。

During the construction of CFG piles, the presence inthe site of unlayered calcium nodules will cause a number of problems, resulting in the construction difficulties, and thus impacting the construction progress. The meth?od of combining the use of automobile drilling poles and the alloy drill bit for walking-typelong spiral drilling machin?eis adopted in this paper, which solved the problems of construction difficulties and the slow progress of the construc?tion, and can provide certain reference for solving similar problems in the future projects.
