高铁车站室外消火栓系统分压供水探讨

摘要

In order to realize the differential pressure water supply for the outdoor fire hydrant system of high speed railway station and meet the requirements of relevant codes at the same time, through the comparative analysis of GB 50974-014 TechnicalCode for fire protection water supply and hydrant systems, TB 10010-2016 Code for design of water supply and drainage for railway and, TB 10063-2016 Code for design of fire prevention for railway engineering, the pipe network layout of the outdoor fire hydrant system of different types of high-speed railway stations is clarified: the outdoor hydrant system without full water spout requirements can share the pipe network with the passenger train's water supply system using a low pressure system; the outdoor fire hydrant system with full water spout requirements should be equipped with a temporary high pressure system and be used in conjunction with an indoor fire hydrant system;in high speed railway station household water supply station without indoor fire hydrant system, outdoor fire hydrant system should be set separately and a temporary high pressure system should be used, providing reference for the outdoor fire protection design of high-speed railway stations.%为使高铁车站室外消火栓系统实现分压供水,同时满足相关规范的要求,对GB 50974-2014《消防给水及消火栓系统技术规范》、TB 10010-2016《铁路给水排水设计规范》和TB10063-2016《铁路工程设计防火规范》等规范进行了对比分析研究.明确了不同类型高铁车站室外消火栓系统的管网布置要求:无充实水柱要求的高铁车站室外消火栓系统可与客车给水系统合用管网,采用低压系统;有充实水柱要求的高铁车站室外消火栓系统应采用临时高压系统,并与室内消火栓系统合用管网;无室内消火栓系统的高铁车站供水站,室外消火栓系统应单独设置,采用临时高压系统.
