In this paper, the safety, flexibility and economic aspects of the prefabricated girder erection program are analyzed and compared. Finally, the simulation of the construction site environment and the prefabricated box girder erection and final implementation are systematically studied. Prefabricated box girder to ensure the safety and quality of construction. By calculating the selection of research equipment and simulating the existing railway line and the surrounding environment in the proper position of the prefabricated beam field, the crane beam is carried out in the field, and the beam path and equipment of the prefabricated beam are studied and studied. And the prefabricated girder erection method. At last, the prefabricated girders are installed on the precast beam, and the prefabricated box girders are erected and the safety of the passing train is guaranteed. In this paper, the whole process of the prefa
