消防水泵共用下的地铁换乘站火灾自动报警系统互联互通方案

Interconnection Scheme of FAS System in Metro Transfer Station Under the Condition for Shared Fire Pump

随着城市轨道交通线网的不断建设,线路交叉形成许多换乘车站。根据GB 50157—2017《地铁设计规范》,除通道换乘车站外,其他形式的换乘车站消防给水系统宜共用。然而,许多换乘车站建设时序往往不同,造成后期建设车站共用先期建设车站消防给水系统时,既有消防水泵控制柜、火灾自动报警系统(FAS)等需要进行不同程度的改造。论文以郑州地铁1号线与14号线换乘站铁炉站、1号线与5号线换乘站郑州东站为例,对先期建设车站消防水泵控制柜预留条件以及后期建设车站FAS系统互联互通方案进行阐述,并提出相应建议供同行参考。

With the continuous construction of the urban rail transit network,many transfer stations are formed.According to the GB50157—2017 Code for Design of Metro,in addition to the channel transfer station,other forms of transfer station fire water supply system should be shared.However,the construction sequence of many transfer stations is often different.As a result,the existing fire pump control cabinets and FAS systems need to be modified to varying degrees when the stations are shared in the later construction of the station.This article takes Zhengzhou Metro Line 1 and Line 14 transfer station Tielu Station,Line 1 and Line 5 transfer station Zhengzhou East Station as examples,to reserve conditions for the early construction of station fire pump control cabinets and the interconnection scheme of the FAS system in the later construction station,and puts forward corresponding suggestions for reference of peers.
