Improvement of Bench Prefabrication Technology for T-Shaped Beam

The design of prefabricated bench is expounded from general requirement, quantity, basic bearing capacity design and camber. According to some practical projects such as Huanghe Highway Bridge project in Xiaolangdi and Nancun, Shihedao Bridge project in Gongyi, etc. Several construction schemes of prefabricated bench are compared and analyzed, and the optimum scheme is obtained. From practice, the improvement of prefabrication technology can speed up construction process, decrease production costs, and guarantee construction quality.
