谈双壁钢围堰封底后渗水处理技术

Discussion on the seepage water treatment technology after double wall steel cofferdam back cover

结合襄阳苏岭山大桥工程实例,介绍了该桥主墩基础与双壁钢围堰的施工方法,并从韧角涌水、护筒内壁涌水、底部涌水等方面,分析了围堰内渗水的原因及处理措施,从而确保承台的施工进度和质量。

Combining with the Xiangyang Suling mountains bridge engineering examples,this paper introduced the construction method of the bridge main pier base and double wall steel cofferdam,and from the toughening angle water gushing,pile casing inner wall water gushing,bottom water gushing and other aspects,analyzed the causes and treatment measures of cofferdam inner seepage,so as to ensure the construction progress and quality of pile cap.
