Construction Technology of the Bailey Truss Girder and Disk Lock Steel Tubular Scaffold Supporting Systems in Cast-in-situ River Crossing Bridge
This article conducts technical research on the combinable application of the"Bailey truss girder and disk lock steel tubular scaffold"supporting system in construction of the cast-in-situ simply supported beam bridges.A comprehensive construction technology and management measures has been established from the perspective of the installation of the Bailey truss girder,the fully supporting scaffold and the distribution beams.And the technical points for preloading,monitoring,and dismantling of the composite brackets were also proposed.The proposed technical measures ascertained the efficient construction of the cast-in structures,and the maximum deformation were kept lower than 11 mm during the whole construction process.
