Providing heavy piping is preferable from the perspective of space utilization efficiency, but it is also not preferable from the perspective of cost.
本発明はＬ記の事情に基きなされたもので、冷却管系と
消火用の配管とを兼用させた洞道冷却システムを得るこ
とを目的としている。The present invention was made based on the circumstances described in L, and aims to obtain a tunnel cooling system that serves both as a cooling pipe system and a fire extinguishing pipe.

時に酸欠状態となるので、速やかに消火される。In the system of the present invention having the above configuration, the Go tube 4 performs cooling within the tunnel, as in the conventional system. When a fire occurs, the valve is opened by the fire detector 7, and the fluorocarbon in the Go pipe is sprayed out from the spray nozzle. As a result, the fire area is cooled and at the same time becomes oxygen-deficient, so the fire can be quickly extinguished.

くてもよいので、原価ト有利である。[Effects of the Invention] As described above, in the present invention, there is no need to install double piping for extinguishing a cooling pipe system, and the space in the tunnel can be effectively utilized. Also, since there is no need to double the piping, it is advantageous in terms of cost.
