Description

Fire detection system in road tunnels }

The present invention relates to a fire extinguishing system for a road tunnel, and more particularly, to a fire extinguishing system for a road tunnel capable of detecting a fire in the road tunnel and promptly taking countermeasures.

As highways, industrial roads, and railway tunnels are actively constructed, it is important to secure the safety of vehicles and passengers passing through the tunnel.

Tunnel fires lead to major accidents without distinguishing between long and short tunnels, causing hundreds of casualties and enormous material loss.

Fires in tunnels can be caused by minor accidents, and in the event of a fire, there is a high risk of spreading to a large-scale disaster, so early response is important.

In accordance with laws and regulations, safety for tunnel passers and vehicles has been secured to some extent by introducing a fire detection system suitable for tunnels.

Currently, in the case of domestic vehicle tunnels, it is recommended to install fire detection facilities only in tunnels over 2km, but in road and railway tunnels, it is impossible to detect a fire immediately in case of fire, and detection is performed only manually. Problems are included.
