Located in Luohu District, Shenzhen, Chunfeng Road is an important traffic road in Shenzhen. The 2017 Chunfeng Road viaduct inspection determined that the bridge is a Type C bridge. In order to improve the safety margin of the bridge, the design uses prestressed carbon fiber panels to improve the bridge's bearing capacity. The ZFPR100-1.4 prestressed carbon fiber reinforcement system of our company is used in this project. The specification of the carbon plate is 100*1.4mm, the length is 9~15 meters, the design tension is 1000MPa, and the reinforcement work is guided by our company.
