Reinforcement of High-Speed Railway Bridge

The traffic volume of the Beijing Shanghai Expressway accounts for a large proportion of heavy goods and trailers, resulting in a rapid decline in highway service levels. In this section, 120 sets of CFRP100 * 2 prestressed carbon plate reinforcement system are used, with a designed tensile strength of 800MPa and a tensile force of 16 tons. It is mainly used for bending reinforcement of 20m prefabricated prestressed concrete continuous box beams.
