Incremental Launching Construction of Steel Box Girders Across Railways and Application of Self-locking Rail Clamps
The Changzhou Benfa Road project spans the existing Beijing Shanghai Railway and Shanghai Nanjing Intercity Railway bridges,which are steel box girder structures and are constructed using the top push method.Firstly,the overall layout and structural design of the cross railway steel box girder were introduced,with a focus on the overall plan and construction steps of the steel box girder launching construction.A detailed calculation and analysis were conducted on the strength,deformation,and stability of the steel box girder,guide beam,and support during the launching construction process.The self-locking hydraulic rail clamp is applied as a pushing reaction frame and rear anchoring device in bridge pushing construction.The working principle,steps,and application of the hydraulic rail clamp are introduced.
