The pushing bridge comprises a main beam, the main beam is divided into a main beam pushing section and a main beam post-pouring section in the longitudinal direction, a plurality of stiff frameworks are arranged at the end of the main beam pushing section and serve as guide beams in the pushing process, and the stiff frameworks serve as load-bearing structures for pouring outer wrapped concrete of the post-pouring section. As a part of a permanent structure, the bearing part participates in bridge forming and operation stage stress; the fixing mode of the stiff framework and the front end of the pushing section of the main beam is an embedded mode or a gusset plate anchoring mode. Compared with the prior art, the utility model has the advantages that the influence on traffic under the bridge can be reduced to the greatest extent; the guide beam can be prevented from being assembled and disassembled, floor stands are reduced, and the construction period is shortened; large machinery is not needed for auxiliar
