WATER SPRAYING/SCATTERING EQUIPMENT FOR TUNNEL

摘要

PROBLEM TO BE SOLVED: To provide an inside tunnel water spraying/scattering equipment which enables safety operation thereof within a short time by performing a scattering of water in a smaller flow rate than that of a main scattering of water for advance notice. SOLUTION: There is provided a small flow rate water scattering means which performs a scattering of water in a smaller flow rate than the main scattering of water for advance notice into a water spraying/scattering section corresponding to the position of a fire in the tunnel before the implementing of the main scattering of water. Another small flow rate water scattering means is provided to perform a scattering of water in a smaller flow rate than that of the main scattering of water for advance notice in the on going direction of vehicles ahead of the water spraying/ scattering section corresponding to the position of the fire in the tunnel before the implementing of the main scattering of water. Furthermore, a small flow rate water scattering means is provided to implement a scattering of water for advance notice in a smaller flow rate than the main scattering of water in the on going direction of vehicles ahead of the water spraying/scattering section during the main scattering of water in the water spraying/scattering section corresponding to the position of a fire in the tunnel.
