地铁地下车站室外消火栓设计探讨

On the Design of Outdoor Fire Hydrant at Underground Metro Station

《消防给水及消火栓系统技术规范》颁布实施后,各地的地铁工程对地下车站室外消火栓系统做法存在较大出入。通过该规范中对室外消火栓系统新增要求的解读,明确了地下车站室外消火栓设置的必要性。结合各地实际地铁工程情况,根据不同的市政给水条件,详细阐述了10个不同的室外消防方案。从合规性、经济性及可实施性等方面分析不同方案的优缺点,并给出最优选的设计方案推荐。

After enactment and implementation of the"Technical Code for Fire Protection Water Supply and Hydrant System",great discrepancies of fire hydrant system at underground stations are found in various subway engineering.Through unscrambling new requirements for outdoor fire hydrant system in the code,the necessity of fire hydrant setting up at underground stations is clarified.Combined with the actual subway engineering situation in various places of China,and according to different municipal water supply conditions,10 different outdoor fire protection schemes are described in detail,the merits and demerits of each scheme are analyzed from aspects of compliance,economy and feasibility,the most preferred design scheme is finally selected.
