高水位差复合式钢板桩围堰技术

High-Water-Level-Difference Composite Steel Sheet Pile Cofferdam Technology

针对复杂水文环境中,传统钢板桩围堰刚度不足、不易合龙等问题,提出了高水位差复合式钢板桩围堰技术,并介绍了其施工工艺和操作要点,对相关工程的建设提供了一定的借鉴作用。

In view of the problems of the traditional steel sheet pile cofferdam in the complex hydrological environment,such as the lack of rigidity and the difficulty of closure,this paper puts forward the composite steel sheet pile cofferdam technology with high water level difference,and introduces its construction technology and operation points,so as to provide a reference for the construction of related projects.
