汤溪河桥异形高低刃脚双壁钢围堰的应用实践

Application of Double-Wall Steel Cofferdam with Irregular Shape and Unequal Height Cutting Edges to Tangxi River Bridge

把双壁钢围堰技术经过改进、创新,应用于西部桥梁的深水基础施工。以异形高低刃脚的方法,解决了钢围堰在陡峭河床上的就位问题。

The techniques for double-wall steel cofferdam are improved, innovated and applied to the construction of deep water foundations of bridges in the west part of China. With the improved and innovated techniques, such as the utilization of irregular shape and unequal height cutting edges for a double-wall steel cofferdam, the problem of positioning the cofferdam on steep riverbed is satisfactorily resolved.
