The experience exchange and discussion and learning of box girder prefabrication technology among large-scale railway construction units are quite close. The prefabrication technology of large-scale railway box girders has gradually matured. The quality of prefabricated box girders will directly affect the overall quality of the entire bridge project, so the construction technology and process control measures in the box girder prefabrication process are particularly important.
