泵钻

Now, CFG technology has totally transferred from driven caisson pile to long screwy drill pipe inner pump pressure.

CFG桩的施工工艺由振动沉管打桩过渡到长螺旋钻管内泵压成桩。

So from the aspects of economical and social benefit, it has a lot of advantages. On the other hand CFG pile with long screwy drill pipe inner pump pressure is low noisy and without muddy water pollution; The process of drilling will not lead to vibration and has the capacity to penetrate hard rock layer; Also the construction is of high efficiency.

并且长螺旋钻管内泵压成桩工艺具有低噪音，无泥浆污染；成孔制桩时不产生振动；成孔穿透能力强，可穿透硬土层，诸如沙层、圆砾层和粒径不大于60mm的卵石层；施工效率高等优点，所以该技术在全国推广后，得到了广泛的应用，目前已成为应用较为普遍的地基处理技术。

Drilling mud is pumped down the inside of the drill pipe, through jet nozzles in the bit, and into the "annulus".

钻井泥浆被泵入钻杆内部，从钻头的喷嘴流入环形空间。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
