Fire disaster ventilation and smoke exhaust method for underground station platform adopting subway full-closed station platform doors

Abstract

The invention relates to the technical field of fire disaster ventilation and smoke exhaust, in particular to a fire disaster ventilation and smoke exhaust method for an underground station platform adopting subway full-closed station platform doors. The method comprises the steps that one of an upgoing side tunnel and a down side tunnel is selected as an auxiliary smoke exhaust tunnel; a row of smoke exhaust valves is arranged above the platform doors; the smoke exhaust valves on the side of the auxiliary smoke exhaust tunnel are opened for smoke exhaust; upgoing side interval tunnel fans anddown side interval tunnel fans are started for smoke exhaust; station tunnel heat exhaust fans are started for smoke exhaust; and station large system fans are started for smoke exhaust. According tothe fire disaster ventilation and smoke exhaust method for the underground station platform adopting the subway full-closed station platform doors, smoke generated during a fire disaster can be exhausted in time, the smoke exhaust efficiency is effectively improved, and the safety of personnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fire ventilation and smoke exhaust, in particular to a method for fire ventilation and smoke exhaust on an underground station platform with fully enclosed subway platform doors. Background technique [0002] In the existing subway design, a typical underground station with a fully enclosed platform door system is generally equipped with four interval tunnel fans, two at each end, which are used as backup for each other, and are used for ventilation and smoke exhaust in the uplink and downlink tunnels. Set up two top-rail and bottom-rail heat exhaust fans, one at each end. Set up two public area smoke exhaust fans, one at each end. After a fire broke out on the station platform, some design schemes set that only the smoke exhaust fan in the public area of ​​the station will be turned on to exhaust smoke, some design schemes are set to turn on a section tunnel fan at each end of the station to assist smok...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fire ventilation and smoke exhaust method for underground stations with fully enclosed subway platform doors, which solves the existing problems in the prior art that the air volume of the fan is not fully utilized, the smoke exhaust effect is not good, and the smoke exhaust efficiency of the tunnel ventilation and smoke exhaust system is assisted. lower question
