浅谈城市轨道交通工程临高压消防给水方式

High Pressure Fire Water Supply in Urban Rail Transit Project

轨道交通工程采用临高压给水系统,设置消防给水泵房和消防水池,消防泵房内设置消防主泵、稳压泵和气压罐。合理的给水方式应是来两种:①消防主泵+高位消防水箱给水方式;②消防主泵+稳压泵+代替高位消防水箱的气压罐给水方式。只有这两种给水方式才是满足规范要求的。

High-pressure water supply system is adopted in rail transit project. Fire-fighting water supply pump room and fire-fighting pool are set up. Fire-fighting main pump, pressure-stabilized pump and pneumatic tank are set up in fire-fighting pump room. Reasonable water supply mode should come in two ways: 1. main fire pump + high-level fire tank water supply mode;2. main fire pump + steady pressure pump + air pressure tank water supply mode instead of high-level fire tank water supply mode. Only these two ways of water supply can meet the requirements of the code.
