复杂地质条件下冲孔咬合桩的施工和应用

Construction and Application of Punching Occluded Pile in Complicated Geological

咬合桩支护结构作为一种新型的基坑围护结构已成功地应用于各地的地铁项目中,具有结构性能稳定,全套筒钻孔施工工艺成熟等优点,文中结合深圳某填海区排洪渠工程实例,证明冲孔咬合桩在海滨滩涂等复杂地质和高水位土层中的适用性。

As a new type of the retaining structure of the foundation pit,the punching occluded pile has been employed well in the subway works and so on because the structure has high supporting behavior and perfect construction procedure with the while sleeve drilling. Based on a reclamation works with discharging floodwater on Shenzhen,indicated that punching occluded pile is suitable to the see beach with complicated geological and high water table area.
