Scope

Main technical content: With the increasing number of dangerous and old hollow-slab bridges, there is an urgent need for a set of mature reinforcement technologies to guide the relevant reinforcement work. Based on the mature reinforcement technologies and engineering cases of hollow-slab beams in various provinces of China, a set of technical specifications for the repair and reinforcement of hollow-slab beams is compiled to solve the current problem of the lack of reinforcement standards for hollow-slab beams, standardize the application of hollow-slab bridge reinforcement technologies, ensure the quality of hollow-slab beam reinforcement, and guide maintenance personnel to carry out the repair and reinforcement of hollow-slab beams scientifically and effectively. At the same time, it can maximize the utilization of the original hollow-slab structure, save national resources, and reduce maintenance costs.
