摘要
研究目的:研究适应于寒冷地区山岭隧道消火栓系统的设计方法,解决消火栓系统的选取及消防管道防冻等设计难题。研究方法:结合有关规范要求,并以内蒙某地区山岭隧道为工程实例,对电伴热保温、放水保温、干式消火栓系统等3种设计方案进行技术和经济分析、论证。研究结果:提出了电伴热保温、放水保温、干式消火栓系统等3种设计方案的系统构成,主要技术参数和设计计算方法。研究结论:电伴热保温、放水保温、干式消火栓系统等3种设计方案均可满足功能要求,电伴热保温方案的造价高;放水保温方案最经济适用;干式消火栓系统方案须得到消防部门的认可,可根据工程环境需要进行选择。
Research purposes： This paper researches the hydrant system design of mountain tunnel in severe cold area and gives solution on antifreezing measures of fire -fighting pipe.
Research methods： Combining with relative specifications and taking severe cold area mountain tunnel in Neimeng province for example , this paper analyses the technic and economic feature about electric tracer heating system, water release thermal retardation system and dry type hydrant system .
Research results ：This paper gives the consists of electric tracer heating system, water release thermal retardation system and dry type hydrant systems, premie preference and methods of calculation.
Research conclusions： Electric tracer heating system, water release thermal retardation system and dry type hydrant systems are all feasible in function. Cost of the electric tracer heating system is higher; water release thermal retardation system is the most economic system; dry type hydrant system must be qualified by fire fighting department. And it depends on the specific engineering to choose the system.
