Deeply-buried subway station hall and long entrance and exit channel combined smoke exhaust system and method
The invention relates to a deep-buried subway station hall and long entrance and exit channel combined smoke exhaust system and method, and belongs to the technical field of subway station fire smoke exhaust. A closed suspended ceiling space above a long entrance and exit channel serves as a natural smoke exhaust air duct, and natural smoke exhaust is achieved through the chimney effect; compared with the prior art, direct contact and mutual mixing between ascending smoke and descending air are avoided, the smoke exhaust efficiency is greatly improved, the definition in the entrance and exit channel is improved, and the technical problem that a mechanical smoke exhaust system in the long entrance and exit channel of the deeply-buried subway station cannot effectively exhaust smoke under the fire working condition is solved.
本发明涉及深埋地铁车站站厅与长出入口通道联合排烟系统及方法，属于地铁车站火灾排烟技术领域，将长出入口通道上方的封闭吊顶空间作为自然排烟风道，利用烟囱效应实现自然排烟，避免了上行烟气与下行空气之间的直接接触和相互掺混，大幅提高了排烟效率，提高了出入口通道内的清晰度，解决了深埋地铁车站长出入口通道内机械排烟系统在火灾工况下不能有效排烟的技术难题。
