摘要: 造成混凝土管桩倾斜与断裂的主要原因为基坑边坡失稳或支护结构破坏、沉桩挤土效应以及挖土与堆土不当等。处理倾斜断裂的管桩的纠直接桩法的主要实施步骤可总结为斜桩纠直、缝隙闭合、填芯补强和质量检验,并得出在具体操作过程中各种问题的解决办法。最后通过一工程实例,说明该法行之有效。

Abstract: The main causes of breakage were concrete tube pile instability of foundation pit or failure of its bracing,soil squeeze due to pile driving,incorrect excavation and incorrect heap of soil.The main steps of the rectification-joining method for broken tube piles were as follows: to rectifying sloping piles,closing cracks,concrete filling and quality testing,with some ways to deal with the problems during practical manipulation.Finally,it was shown with a practical case that this method was effective.
