[0002] Reinforced concrete box girders are one of the important structures in bridge engineering. According to the method of concrete pouring, they are divided into precast box girders and cast-in-place box girders. The inner mold of the precast box girder is mainly to achieve the geometric dimensions required by the design. The template is made of different materials and has sufficient bearing capacity to withstand the dead load generated by concrete and the live load generated by small machinery and construction personnel. Among them, the precast box girder is prefabricated in advance at an independent site and then hoisted after the lower structure of the bridge is completed. It can effectively avoid cross-construction interference, greatly improve the progress of the project, and save construction time. Therefore, it has been widely used.
