In order to solve the design and construction problems existing in the construction process of the steel structure pedestrian overbridge for Guangzhou Olympic Sports Center Station,through theoretical calculation,on-site confirmation and scheme research,the inner pulling continuous jacking construction technology is put forward,which successfully solves the construction problems of limited clearance under the bridge and tight construction land,saves construction land and reduces the workload of pipeline relocation.At the same time,the traditional guide beam system,slideway system and synchronous jacking system are improved and innovated,which enhances the stability of the jacking system,reduces the construction difficulty and improves the work efficiency.Practice shows that the use of inner pulling continuous jacking construction technology shortens the time of jacking construction points,reduces the impact of construction on the traffic of passing vehicles,and ensures the safety of railway and highway traffic and existing equipment.
