- Title:
- Outdoor Fire Protection System Design of Underground Rail Transit Station under Non-dual Water Source
- 摘要:
- 轨道交通地下车站室外消火栓系统设计目前已成为业内关注重点，在《地铁设计规范》(GB 50157—2013)、《消防给水及消火栓系统技术规范》（GB 50974—2014）及《地铁设计防火标准》（GB 51298—2018）中对此要求有一定差异。结合既有地铁设计案例，针对非双水源供水情况下几种常见的室外消火栓系统设计方案进行分析。在满足当地消防部门要求的前提下，从合理性、合规性、安全性及经济性角度考虑，提出了在非双水源供水情况下，地铁车站室外消火栓系统设计流量按照20 L/s取值，单水源时在车站对角出入口分别设置室外消火栓并由市政供水；无市政供水条件时由室外144 m3消防水池及室外消防管网系统为每个车站出入口室外消火栓供水以满足消防要求的设计结论。
- Abstract:
- At present, the design of outdoor fire hydrant systems in underground rail transit stations has become the focus of the industry. There are certain differences of design requirement among Code for Design of Metro (GB 50157-2013), Technical Code for Fire Protection Water Supply and Hydrant Systems (GB 50974-2014 ) and Standard for Fire Protection Design of Metro (GB 51298-2018). Combined with the existing metro design cases, several common design schemes of outdoor fire hydrant system under the condition of non-dual water source supply were analyzed. On the premise of meeting the requirements of the local fire department, a scheme was proposed in view of rationality, compliance, safety and economy. The design flow rate of the outdoor fire hydrant system of the underground station was 20 L/s. For a single water source, outdoor fire hydrants were installed at the diagonal entrances and exits of the station and connected to the municipal water supply. When there was no municipal water supply network, the outdoor fire-fighting pool with volume of 144 m3 and outdoor fire-fighting pipe network system would supply water to the outdoor fire hydrants at every entrance and exit of the station to meet the fire protection requirements.
