Abstract

The invention relates to the field of rail transit ventilation and smoke exhaust, and provides a fire ventilation and smoke exhaust system and method for separated island type subway underground station platform. A separated island type subway underground station comprises two platforms which are separated from each other and two station halls arranged above the two platforms, the two platforms communicate with the two station halls through channels respectively, tunnels are separated from the platforms through platform doors, and the two ends of each tunnel are connected with tunnel smoke exhaust subsystems respectively. A smoke exhaust valve is arranged above each platform door, each tunnel is connected with a heat exhaust subsystem, the platform and the station hall on each side share one set of air supply and smoke exhaust system, and each air supply and smoke exhaust system is used for supplying air to or exhausting smoke from a platform public area and a station hall public area.According to the separated island type subway underground station platform fire ventilation and smoke exhaust system, the smoke exhaust amount is increased by at least one time on the premise that the equipment purchase cost is not remarkably increased, and efficient smoke exhaust is achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit ventilation and smoke exhaust, in particular to a fire ventilation and smoke exhaust system and method for a separate island type subway underground station platform. Background technique [0002] As a modern urban rail transit tool, the subway undertakes more and more important tasks of passenger flow transportation. Due to the limited space inside the city, most of the urban subway stations are underground stations. In the operation safety of underground stations, the greatest hazard is the casualties caused by the smoke generated by combustion in subway stations and subway tunnels and the diffusion of toxic substances. Subway fires are more dangerous than ground building fires. Once a fire breaks out, the losses are often very serious. The main manifestations are: first, the underground station has insufficient oxygen supply, incomplete combustion, thick smoke, and a large amount of smoke...
