Single-span steel box girder pushing method for viaduct
The invention belongs to the field of bridge construction, and particularly relates to a single-span steel box girder pushing method for a viaduct. The method includes the steps that firstly, a hydraulic synchronizing pushing device is installed; secondly, formal sliding operation is started; thirdly, fine adjustment is conducted, a steel bridge is supported by a temporary buttress after fine adjustment is conduced, and a next steel bridge slides; fourthly, each span serves as a sliding unit and other spans of steel bridges of a linkage are pushed and welded sequentially; fifthly, the steps mentioned above are repeated; sixthly, a steel bridge on a splicing platform is installed, a hydraulic synchronizing pushing system is detached, the positions of local supports are finely adjusted, provisional measures are removed, and the steel bridges are installed. The method has the technical advantages that installation is simple and convenient and efficiency is high.
