悬挂钢围堰施工技术

Construction Technology of Suspension Steel Cofferdam

悬挂钢围堰是以桩基钢护筒为受力支撑而构造的悬挂于水中的钢围堰,是施工水中高桩承台的一种措施性结构。本文以小河溪大桥悬挂钢围堰[1]施工过程为例,详细介绍了悬挂钢围堰的构造及施工流程,为今后类似工程施工提供参考。

Hanging steel cofferdam is a kind of steel cofferdam suspended in water,which is constructed with pile foundation steel retaining tube as force support,and is a kind of measure structure of pile cap in construction water.Taking the construction process of suspension steel cofferdam of Xiaohexi Bridge as an example,this paper introduces the structure and construction process of suspension steel cofferdam in detail,which provides a reference for similar construction in the future.
