Design and construction of temporary hoisting system for suspension rod replacement of concrete-filled steel tube arch bridge

Le résumé fourni par la source

In this paper, the selection, composition and main design points of flexible temporary hoisting system in the suspension rod replacement of concrete-filled steel tube arch bridge are introduced, and the calculation and verification are carried out by finite element program. In addition, the related installation and construction technology of the temporary hoisting system are introduced, and the engineering practice proves that the flexible temporary hoisting system realizes the boom replacement safely and effectively. At the same time, the practice can provide reference for the replacement of similar bridge derrick and the design and construction of the same type temporary hoisting system.
