METHOD FOR VENTILATING UNDERGROUND STRUCTURE IN THE EVENT OF FIRE

摘要

A ventilating method for an underground structure in the event of fire is provided to control all ventilation devices in a station building and all ventilation devices in a tunnel to operate in air distribution or exhaust modes as needed, and therefore to prevent a fire spread. A ventilating method to be applied to an underground structure that is formed of a tunnel(200) and a plurality of partitioned station buildings(100) in which both the tunnel and the station building are equipped with fire sensors(110,210) and ventilation devices(120,220), includes the steps of: if fire is sensed by a fire sensor in one of the station buildings, all of the ventilation devices in the other station buildings operate in an exhaust mode, while all of the ventilation devices in the tunnel enter air distribution mode; and if fire is sensed by a fire sensor in the tunnel, all of the ventilation devices in every station buildings operate in an air distribution mode, while the other ventilation devices in the tunnel operate in an exhaust mode.
