水中双壁钢围堰设计与施工技术研究

Research on Design and Construction Technology of Double Wall Steel Cofferdam in Water

本文通过对上横沥大桥深水低桩承台双壁钢围堰的设计、制作、下沉、吸泥、封底施工工艺的介绍,总结了深水条件下双壁钢围堰设计及施工的技术要点,对于采用双壁钢围堰施工深水承台基础的类似工程具有一定的借鉴意义。

Based on the introduction of the design,fabrication,sinking,mud suction and bottom sealing construction technology of the double wall steel cofferdam for the deep-water low pile cap of shanghengli bridge,this paper summarizes the technical points of the design and construction of the double wall steel cofferdam under the deep-water condition,which is of certain reference significance for similar projects of the deep-water abutment foundation construction with the double wall steel cofferdam.
