摘要
研究目的:消火栓系统是地铁消防设计的重要组成部分,在寒冷地区的地铁设计中,如按照常规方式采用湿式系统,区间隧道也需要保温,存在事故隐患。采用干式系统可以减少事故隐患,节约能源。研究方法:采用理论分析、汲取国外地铁工程实例经验及地铁运营的实际相结合的方式进行研究,并通过消防专题会议专家论证。研究结论:在寒冷地区的地铁中,区间隧道会出现的气温在0℃以下;采用干式消火栓系统不需要保温;区间干式消火栓系统从时间上可以满足消火栓使用要求;半自动干式系统应设置快速启闭阀、排气阀等装置。
Research purposes： Hydraulic system system is designed in the traditional way, the is the important part of the subway. In the cold area, if the hydraulic pipeline in the tunnel needs heat preservation and it would cause accidents. In order to diminish the accidents in the tunnel and save the energy, dry hydraulic system should be adopted in the tunnel.
Research methods：This paper combined academic analysis, the operation practice and the research of the overseas instance in the subway. Also a special technical meeting with the fire fighting department was held to discuss the issue with many experts.
Research conclusions： In the cold area, the temperature of the tunnel could be under zero degree ; Dry hydraulic system needs no heat preservation measures; Dry hydraulic system can meet the time requirements of hydrant operation; Draintap, deluge valve and other apparatus are needed for the dry system.
