The embodiment of the invention provides a subway train station and a smoke exhaust method thereof. According to the method, smoke exhaust is achieved for a station public area through tunnel fans without additionally arranging special smoke exhaust fans for smoke exhaust. A smoke exhaust duct is located at the top of a rail area of a tunnel and selectively communicates with the station public area and an inner cavity of a first air chamber, so that when a fire breaks out in the station public area, the station public area, the an inner cavity of the smoke exhaust fan and the inner cavity of the first air chamber communicate with one another, the inner cavity of the first air chamber is separated from the rail area, then smoke of the station public area is exhausted by the first fan through the smoke exhaust duct and the first air chamber, and then smoke exhaust is achieved. The smoke of the station public area does not need to pass through a shielding door, so that the shielding doordoes not need to be opened, and therefore the risk that evacuation people fall off the rail area is avoided. The smoke exhaust duct is located at the top of the rail area and does not need to occupy the space of the station public area, the layer height of a station layer is not increased due to the arrangement of the smoke exhaust duct, and the civil engineering scale and the arrangement difficulty of pipeline layout are not increased.
本申请实施例提供一种地铁列车站台及其排烟方法,本申请实施例通过遂道风机对站台公共区进行排烟,不需要增设专门用于排烟的排烟风机。由于排烟风道位于遂道的轨行区的顶部,且择性地连通站台公共区和第一风室的内腔,当站台公共区发生火灾,站台公共区、排烟风道的内腔以及第一风室的内腔连通,第一风室的内腔与轨行区截止,站台公共区的烟气经第排烟风道和第一风室被第一风机抽走,以实现排烟。站台公共区的烟气不需要经过屏蔽门,故屏蔽门不需要开启,避免了疏散人员掉落轨行区的风险。排烟风道位于轨行区的顶部,不需要占用站台公共区的空间,不会由于排烟风道的布置而增加站台层的层高,不会增加土建规模和管线综合的布置难度。
