In order to ensure the safe and efficient construction of large cantilever prestressed capping beams and improve the construction quality of viaduct projects,this paper studies different support systems combined with engineering cases,by comparing the construction efficiency,social benefit and economic benefit of three kinds of cover beam support,it provides important reference for the selection of large cantilever prestressed cover beam support under different environment.
In the reconstruction project of Nanxun to Wuxing section of 318 National Highway, the main bridge of Baimitang Bridge adopts the design of three-span continuous beams. The main technical problems in the construction are as follows: the span and width of the bridge deck are larger than that of the conventional continuous beams, the force is more complex, and the design and processing of hanging basket template are difficult. In continuous beam construction, basket design and construction monitoring are the key links, and linear control is the priority among priorities. In this paper, combined with the construction of the continuous beam of the main bridge of Baimidang Bridge, the design and construction monitoring methods of the hanging basket template are expounded,the successful completion of handover and acceptance of the closure has a strong reference significance for similar projects.
