Reversible and integrated complex system for controlling fires in tunnels and providing protection in road or rail tunnels and their walkways

摘要

The system utilizes continuous water or foam spraying ramps (8), supplied in sections from a wet stand pipe (5), with a priority operating mode triggered instantly by the user, and an automatic operating mode. The device provides users with instant protection on the walkway (12), sheltered by a continuous longitudinal hood (11), in a clear atmosphere, facilitating the use of extinguishers. Articulated and retractable sheaths (21) provide supply vehicles with fresh air. The inventive system is particularly designed for controlling fire risks, and for decontamination, in long road and railway tunnels.
