The reporter learned from related parties that the super-large bridge and tunnel preventive maintenance management system developed by Xiamen Road and Bridge Management Company has been praised by experts across the country and has been promoted and applied in the management of expressways inside and outside the province.

The preventive maintenance management system for super-large bridges and tunnels was developed by the Road and Bridge Management Company for the Haicang Bridge in cooperation with Danish experts. It was first adopted on the Haicang Bridge and was first applied on the Qinling Highway Tunnel in Shaanxi outside Xiamen in 2003. At present, our province The expressway has fully promoted this management system. Using this set of management, the diseases of bridge and tunnel facilities can be eliminated in the initial stage, avoiding serious damage to the facilities and affecting safe driving, and the maintenance and management cost of bridge and tunnel can be reduced by 20%.

At the National Bridge and Tunnel Maintenance Management High-level Forum held in our city a few days ago, experts from all over the country gave a high evaluation of this management system. According to reports, the road and bridge management company hopes to further improve this set of preventive management methods in the management of the Xiang'an Tunnel.

Our undersea tunnel is the first inland undersea tunnel and the largest tunnel in the world. It has just been successfully completed and opened to traffic. I want to use the wisdom of the country to better manage the tunnel maintenance.
