RESEARCH ON HOISTING CONSTRUCTION TECHNOLOGY FOR PREFABRICATED BOX GIRDERS OF UNDERPASS EXISTING ELEVATED BRIDGES
With the rapid development of urban transportation construction,the intersection of new and existing lines is inevitable.The hoisting of box girders has become an important critical node when crossing and crossing existing lines.Reasonable arrangement of box girder hoisting can ensure the safe and efficient progress of the project.Taking a renovation project in Beijing as an example,this study analyzed the technical difficulties of the project and summarized the lifting of box girders under the newly-built overpass ramp crossing Changping Line.The research results can provide engineering experience for similar projects.
