CONSTRUCTION METHOD FOR ASSEMBLING STEEL BOX GIRDER ABOVE TRAMCAR

摘要

A construction method for assembling a steel box girder (1) above a tramcar, comprising: erecting a plurality of temporary supports (2) along the arrangement direction of the steel box girder (1), assembling the steel box girder (1) on the temporary supports (2), and sequentially disassembling the temporary supports (2) after assembly. On the premise of ensuring the safety of a rail foundation and that of a power grid, the construction method performs assembling construction on the steel box girder (1) above a rail (3), and also ensures the construction efficiency and the safety of rail transit.
