| Abstract: | The Wuhan Yangtze River Tunnel on Sanyang Road is the first rail-and-road shield tunnel in the world, and the fire protection design is the key and difficult point to ensure the safety of the project operation. Aiming at the engineering characteristics of the rail-and-road river-crossing tunnel, fire hydrant system, foam-water spray system and fire extinguisher system are adopted in the fire protection design together with automatic fire extinguishing system and gas fire extinguishing system. Design principles, system layout, key technical parameters, selection of fire protection system equipment and technical innovation are concisely explained.. |
