Foundation and Steel Cofferdam Design and Construction in A Project

水中基础施工是桥梁施工中控制工期的重要节点,该文阐述了在枯水期通过先旋挖钻孔施工桩基础再进行钢围堰施工,可避免常规施工方法在钢围堰上搭设钻孔平台进行水上钻孔施工的安全风险,为类似工程提供一定的参考。

Foundation construction under water is a key step to control the entire bridge construction duration. It is suggested in this paper to first con-struct pile foundation by rotary drilling, thus the safety risk from drilling construction above water by establishing drilling platform on steel cofferdam can be avoided. It can be referenced by similar projects.
