深水大直径钻孔灌注桩施工工艺

Construction Technology of Large Diameter Cast-in-situ Bored Piles in Deep Water

就张松互通立交桥在深水条件时利用钢管桩钻孔平台施工大直径钻孔灌注桩的施工工艺进行了探讨与实施,并在实施过程中取得了良好的效果。

In this paper, as Zhangsong interchange was constructed in the condition of deep water, the construction tech- nology of large diameter cast-in-situ bored piles and drilling platform using steel pipe pile was discussed and adopted, and the implementation had achieved good results.
