[0002] Box girder prefabrication is the production of large prefabricated parts required for railway construction. It involves several key steps. First, it is necessary to establish a suitable prefabrication site and build infrastructure to support the production, storage and transportation of the beam body. Then, it is necessary to build a beam-making pedestal as a basic platform and design a steel formwork to be placed on the pedestal. After that, it is necessary to tie the steel skeleton in the steel mold according to the drawings, including main bars, stirrups and various embedded parts. The box girder is in the shape of a hollow box. When its steel frame is constructed, the two sides can be built with molds as supports.
