Modularized railway box girder hydraulic formwork structure

The invention discloses a modularized railway box girder hydraulic formwork structure, and relates to the technical field of box girder formworks, the modularized railway box girder hydraulic formwork structure comprises a bottom formwork, outer formworks are arranged on the two sides of the bottom formwork, a side frame is fixedly installed on one side of each outer formwork, and a driving positioning mechanism used for driving the outer formworks to move is arranged below the side frames; a plurality of butt joint columns are fixedly connected to the side, close to the outer mold, of the bottom mold, and a plurality of butt joint holes are formed in the bottom edge of the side frame; efficient use of the outer mold is achieved by driving the outer mold to move, meanwhile, the outer mold is divided into a plurality of subunits in the length direction of the outer mold, all the subunits are independently arranged and can be independently controlled and driven, the production requirements of box girders with d
