Fire Protection Design of Subway in Transportation Hub in Cold Region

消火栓系统是地道消防的重要组成部分。研究的主要目的是结合实际工程探讨寒冷地区地道消防的设计思路。首先,结合规范要求分析了消火栓系统布局的影响因素;其次,对地道常用防冻措施的适用范围进行了分析,地道长度小于750 m时宜采用干式消火栓系统,大于750 m时宜采用电伴热措施;最后,通过实际计算提出了电伴热保温与干式消火栓系统的设计要点。

The hydrant system is the important component of fire protection in subway. The main purpose of the study is to discuss the design thought of fire protection of subway in the cold region by the practical projects. This paper firstly analyzes the influencing factors of distribution of hydrant system according to the code requirements, then analyzes the application range of common anti-freezing measures for the subway, the dry hydrant system suitably used when the subway length is less than 750 m and the electric heat tracing measures suitably used when the subway length is larger than 750 m, and finally puts forward the design essentials of electric heat tracing thermal insulation and dry hydrant system by the practical calculation.
