Abstract

A tunnel relief device includes an arcuate frame member, at least two fire-extinguishing arms, and a transport assembly. The arcuate frame member traverses along a length of the tunnel via first guide rails positioned on an inner surface of the tunnel. The fire-extinguishing arms are positioned on an inner surface of the arcuate frame member and traverse along the inner surface of the arcuate frame member via second guide rails to extinguish fire induced in the tunnel. The transport assembly comprises extendable arms and housed in an upper region of the arcuate frame member. The extendable arms are movable in a horizontal or vertical direction. The transport assembly is rotatably engaged to the upper region of the arcuate frame member to transport the vehicles in the tunnel from a first position to a second position to ensure safe and unobstructed movement of the vehicles in the tunnel.
