| 摘 要： | 干法内击沉管碎石桩通过重锤冲击导管底部的碎石塞，并带动导管同步挤土下沉而形成桩孔，然后拔管，击穿底塞并依次投石，夯实，拔管。循环反复进行直至桩顶形成碎石桩体。使用该方法可缩短工期，技术经济效益显著。

| Abstract: | The dry internal sinking tubular gravel pile is made of the following continuous repetitive procedures namely:(1) the feeding of gravel into tube with heavy hammering,(2)the tube-end's lid being gradually pressed and removed,(3)the synchronistical settlement of tubular gravel and soil being carried out simultaneously,and lastly (4)tube extraction.These continuous repetitive procedures for the making of dry internal sinking tubular gravel piles have been achieved until a group of gravel piles completed.These measures have shortened the period of construction and brought about good technical and economical results. |
