Key Construction Techniques of Large-diameter Single-pile Single-column Variable-diameter Cylindrical Pier without Tie Beam
After my country's highway construction has achieved leapfrog development,the construction concept has been continuously upgraded,and the need for environmental protection in highway network construction has gradually become more prominent.In order to reduce the environmental disturbance caused by pier construction and reduce the impact of bridge construction on the water blocking rate and the evolution of the Yellow River bed,the ground beam structure design of the south auxiliary bridge of the Yellow River Grand Bridge was canceled during the design stage and replaced by large-diameter"vase piers"piers.For the roof-tied beam structure,this article explains the adjustable modulus hoop method,the mechanical connection process of the variable-diameter steel cage,and the manufacturing and installation process of the variable-diameter steel cage,aiming to provide a reference for similar projects.
