[0002] The box girders of reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders. The box girders prefabricated in an independent site can be erected in combination with a bridge erection machine after the lower project is completed, which can speed up the progress of the project and save construction time; cast-in-place box girders are mostly used for large continuous bridges. There are two main types of common materials, one is prestressed reinforced concrete box girders, and the other is steel box girders. Among them, prestressed reinforced concrete box girders are constructed on-site. In addition to longitudinal prestress, some also have transverse prestress; steel box girders are generally processed in the factory and then transported to the site for installation.
