Large Bridge Swivel Construction Technology

Bridge swivel construction technology is employed in the case that concreting cannot be done directly by erecting formwork. Firstly,the bridge shall be prefabricated in an area which is suitable for construction, and then,by using some machines and equipment,the bridge body on the rotatable bearing shall be turned to the axis position of the bridge so as to realize the closure of the bridge.Diff erent conditions and shapes of bridge bodies have their own characteristics in construction methods.This paper introduced the construction of the bridge body with large swivel weight,large swivel angle and long beam body, which can provide reference for similar bridge construction.
