| 摘 要： | 处理埋管导致的断桩时常会出现内护筒不能下沉的问题。应用空心“子母”钻对桩基进行扩孔,通过减小内护筒周边的摩擦阻力,可使内护筒顺利下沉到断桩位置。

| Abstract: | The problem of that the internal drive pipe can't submerge often occurs when the piles were brocken that caused by the treatment of the buried pipes. Applying the hollow "primary-secondary" driller to expand the holes for reducing the peripheral frictional resistance of the internal drive pipe can make the internal drive pipe submerge to the position of the broken pile. |
