《消防给水及消火栓系统技术规范》在地下车站适用性研究

Analysis and Discussion of Rail Transit Engineering and Underground Station Fire Hydrant System Design

对《消防给水及消火栓系统技术规范》及《地铁设计规范》中地下车站室外消防给水系统设计、室外消火栓及消防泵房设置等相关条款进行对比,分析地铁工程室外消防给水系统消防用水量取值标准、室外消火栓设置位置及数量、消防泵房设置位置等方面按《消防给水及消火栓系统技术规范》的要求进行设计在工程实施上存在的难度。列举国内各地轨道交通单水源条件下室外消火栓给水系统在室外消防水池、消防泵组及市政消火栓设置方面采取的多种组合设计方案,同时以中南某城市轨道交通为例,对不同的设计方案进行技术经济比较分析。通过对轨道交通消防给水系统既有设计方案的总结分析,提出轨道交通消火栓系统设计应根据地铁工程特点,结合消防实际救援,采取最优设计方案。

This study highlights,analyzes,and compares the technical specifications for the underground subway station's outdoor fire water supply system,fire hydrant systems,and fire pump room.An analysis of the outdoor fire water supply system is performed according to the metro engineering fire consumption value standard,in which the location and water quantity of the outdoor fire cock,the fire pump room's location,and other such factors,were set according to the technical specifications for the fire water supply and fire hydrant system.This paper enumerates the domestic rail transit around a single outdoor fire hydrant water supply system under the conditions of water availability in the outdoor pool fire,fire pump group, and municipal fire hydrant.A variety of combinations are considered for the Zhengzhou Metro Line 10 as an example to compare the technical economy of the design schemes.
