RESEARCH ON JACKING CONSTRUCTION TECHNOLOGY OF SEPARATED INTERCHANGE BRIDGE STRUCTURE
The development of traffic infrastructure has led to more and more cross-over of lines,and the new lines have clearance requirements under the existing lines.Under certain restrictive conditions,it is necessary to jack up the Bridges of the existing lines to solve the problem of insufficient clearance.In this paper,based on a separate overpass over Rongwu Expressway project,the main work content of bridge jacking is sorted out,the technical process of the overall jacking construction of bridge structure is introduced,the key points of the overall jacking construction technology of bridge structure are summarized,and the whole process of the overall jacking construction technology of bridge structure is monitored and analyzed.By applying this technology,the problem of insufficient clearance across Rongwu Expressway on a separate interchange has been solved successfully.The research results can provide some reference for future bridge maintenance and reinforcement work.
