Selection of design alternatives of water pillar cofferdam of main bridge of Fuyuan road Bridge

结合福源路大桥主桥水中墩围堰设计过程,提出了3个方案,即双壁钢围堰、钢板桩围堰、锁口钢管桩围堰,主要从围堰的施工、技术、安全、经济等方面进行了比选,选择出最佳方案,以达到缩短工期、节约成本和安全可靠的目的。

Combining with design process of water pillar cofferdam of main bridge of Fuyuan road Bridge,it proposes three schemes including double-wall steel cofferdam,steel plate pile cofferdam,and steel pipe pile cofferdam with locked edge,mainly makes an comparison from aspects of the cofferdam construction,technology,security,and economic and other aspects,and then selects optimum scheme,so as to shorten construction schedule,save cost,and ensure reliability and safety.
