潇河大桥钻孔桩施工工艺及对清孔问题的探讨

On exploration for construction craft of bored piles on Xiaohe Bridge and hole clearing issue

从潇河大桥钻孔灌注桩的施工准备、钻孔作业、清孔、下钢筋笼、设导管、灌注水下混凝土方面论述了钻孔桩的施工工艺,提出了原浆清孔是保证灌注桩质量行之有效的方法,为类似工程施工积累了经验。

The paper indicates the construction craft of the bored piles including the construction preparation,the drilling work,the hole clearing,the descending reinforcing cage,the implant of catheter,and the pouring underwater concrete of the bored piles on Xiaohe Bridge,and points out the protoplasm hole clearing is the effective method to ensure the bored pile,so as to accumulate the experience for similar engineering construction.
