Railway laying and bridge erecting method of assembly plate type railway structure

The invention discloses a railway laying and bridge erecting method of an assembly plate type railway structure. The railway laying and bridge erecting method comprises the steps of constructing a railway engineering surveying plane, an elevation control network and foundation steel bars, performing paving to construct a reinforced concrete foundation or a bituminous concrete foundation, prefabricating railway boards, conducting elevation scanning measurement and control on the surface of the foundation, simulating railway board and foundation assembly, conducting construction layout on the surface of the foundation, configuring a viscoelastic cushion layer, putting the railway boards in place and performing railway board limiting pin or limiting boss construction. The railway construction organization is flexible, the railway laying construction organization number can be decreased, a railway laying construction period can be reasonably shortened to reduce the overall construction period pressure of a railway transportation project, and the railway laying and bridge erecting method facilitates crashing on the premise that the railway construction quality is ensured under special situation and has obvious social benefits and economic benefits.
