Bridge beam slab standardized prefabricating construction method and standardized prefabricated beam slab

The invention discloses a bridge beam slab standardized prefabricating construction method, and provides a pedestal. The method comprises the following steps: binding reinforcing steel bars into a reinforcing steel bar framework on the pedestal to make the reinforcing steel bar framework provided with two webs which are oppositely arranged and a bottom plate for connecting the two webs, and placing an inner film between the two webs to bury a plurality of first prestressed pipelines in the webs; arranging a plurality of second prestressed pipes between the two webs; installing a side mold andan end mold matched with the steel bar framework to form a pouring space in a surrounding manner; pouring concrete into the pouring space; loading a plurality of first steel strands into the first prestressed pipes, and tensioning the plurality of first steel strands; and arranging a plurality of second steel strands in the second prestressed pipes, and tensioning the second steel strands. Compared with the prior art, the
