海上桥梁钢护筒施工技术探讨

Discussion on the Construction Technology of Steel Casing for Offshore Bridges

大型水上桥梁桩基施工中的常用施工技术措施——钢护筒,主要是用来稳定孔壁、防止坍孔,还可以用来隔离地表水、引导钻头方向、固定桩位不变、保护原操作工作面等。

The common construction technology measure in pile foundation construction of large-scale offshore bridges is steel casing,are mainly used to stabilize the hole wall and prevent collapse.It can also be used to isolate surface water,guide the direction of drill bit,fix the pile position unchanged,and protect the original working face.
