1. Chengdu Metro 1 1 Line: Chengdu Metro 1 1 Line adopts a new type of steel tunnel escape pipe instead of the traditional concrete pipe, which makes the tunnel escape passage more convenient and improves the safety of the subway.
2. Yangtze River Highway Bridge: The tunnel escape passage on the Yangtze River Highway Bridge adopts a new type of steel tunnel escape pipeline. Due to the super fire resistance of steel pipe, it can ensure the safe escape of tunnel in emergency.
3. Chongqing Yangtze River Tunnel: Chongqing Yangtze River Tunnel is a key project. In order to ensure the safe passage of the tunnel, a new type of steel tunnel escape pipeline is adopted, which strengthens the escape passage of the tunnel and enhances the fire resistance of the tunnel.
4. Tibet Highway: Tibet Highway is a highway running on the plateau. In order to meet the special environmental needs, a new type of steel tunnel escape pipeline is adopted, which makes the tunnel escape smooth and safe and ensures the safety of traffic and passengers.
Generally speaking, the new steel tunnel escape pipeline has been widely used in public places such as subways, highways and tunnels. With the progress of technology and the gradual expansion of application scope, there will be more and more application cases of new steel tunnel escape pipes.
