- 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.
