INSTALLATION AND CONSTRUCTION TECHNOLOGY OF LONG SPAN BIDIRECTIONAL MULTI-LANE STEEL BOX BRIDGE
There are many problems in the traditional long-span structure construction in the construction industry.At the same time,the technical requirements and standards of the construction industry are increasingly strict.The installation and construction technology of long-span steel box bridge is objectively necessary to replace the traditional structure construction in the promotion and application of long-span bridge structure construction.Through in-depth analysis and research on the installation and construction technology of the large-span bidirectional multi-lane steel box bridge,combined with the heavy and difficult problems existing in the construction process,specific countermeasures are proposed in view of the unsafe factors existing in the construction process,and the installation and construction of the large-span steel box bridge is successfully completed by using the drag and slip construction technology.Compared with the traditional hoisting construction technology,the technology has high safety,stability and economy,and is suitable for the environment with complex terrain,and has strong industry promotion significance.
