Analysis on the Application of Travel Inching Technology for Swivel Continuous Beam
At present,the construction technology of swivel continuous beam has been widely used in the construction adjacent to business lines.However,the swivel structure often experiences over swivel and inadequate swivel during the inching swivel process,which not only prolongs the operation time,but also increases the risk of construction adjacent to business lines.The travel inching technology can not only clarify the functional relationship between the beam end travel and the traction steel strand travel,achieving millimeter-level precise control,but also enable the swivel structure to reach the predetermined position quickly and accurately,achieving the goal of fully utilizing the skylight time point.Based on the engineering case of the swivel continuous beam swivel construction of the newly-built Jinan-Laiwu high-speed railway overcrossing the Watang-Rizhao railway super-large bridge,this paper summarizes the relevant principles and calculation steps of the travel inching technology,aiming to provide reference for the future swivel construction engineering adjacent to business lines.
