This paper analyses the working principle of CFG pile composite foundation and construction technology, especially focuses on the comparison with other piles in construction skills. Aiming at the geological characteristic of haugh in Zhengzhou, the theory of seepage deformation and the pore expanding were applied in the research work of CFG pile impacting the surrounding environment. Then the controlling solution was listed in the paper.

为此，通过对CFG桩复合地基工作机理、施工方法的分析研究，特别是CFG桩与其它桩型施工方法的对比分析(如CFG桩与沉管灌注桩、CFG桩与钻孔灌注桩比较分析)，针对泛滥平原工程地质的特点，运用渗透变形原理、小孔扩张理论等较为深入地研究了CFG桩环境效应，并提出了相应的控制措施，主要研究成果归纳如下：(1)本文提出了针对泛滥平原工程地质单元地区"二元"结构地层，CFG桩长螺旋钻管内泵压施工对周围环境的扰动机理。

Moreover drilling measures in different strata are pointed out,which are firstly drilling without slurry in part of silty clay layer,secondly adopting double-bottom bailing bit and bore directly and abandoning slurry with impact drilling rig in muddy clay layer,thirdly selecting short screw auger at low speed in gravel layer,finally choosing rock-socketed drilling tube in shaly sand layer.

指出旋挖钻机在不同地层中的钻进措施：部分粉质粘土层中可用清水或干孔钻进，淤泥质粘土层中采用双底捞砂钻头、直接用冲击钻机钻孔弃浆，圆砾层中采用短螺旋钻头低速钻进，泥质砂岩层中采用嵌岩钻筒钻进等措施，保证施工工期满足架梁节点要求。

The machine equipments needed has spiral drill press and drill to expand machine or diving drill press.

所需机械设备有螺旋钻孔机、钻扩机或潜水钻孔机。

Numerical controlled program was compiled with ETA code. The baffles were welded into a pile, then the holes were drilled using milling cutter and twist drill. The baffles were installed on Mitsubishi numerical controlled machine, and numerical controlled process was realized. This can improve production efficiency, which makes it possible that helix-baffled tubular heat exchangers can be widely applied in factory.

在MITSUBISHI操作系统的数控钻铣床上，采用特殊的刀具，将折流板点焊为一擦，装夹在旋转工作台上，使之与刀具成一个固定角度，实现了阶梯式螺旋折流板上孔的加工，解决了制造的难题，提高了生产效率和钻孔精度，为螺旋折流板管壳式换热器的推广应用提供了可能。

Warning device with safety and durability in the room. M85D leader can rotate at 135° and the pile hammer and flight auger can be hanged on it at the same time.
