城市轨道交通郊区线车站消防给水设计

Design of Water Supply for Stations on Suburban Lines of Urban Rail Transit

随着城市扩张和卫星城的发展,郊区线逐渐成为轨道交通工程建设的一个重要方向。针对郊区线远离城区车站的特点,研究其给水设计尤其是消防给水设计的指导思路和方案。提出根据近、远期的车站周边水源条件,统筹、优化水源方案的设计思路;为保证偏远车站自救需要,强调设置消防水池、消防车取水口、室外消火栓管网及加压设施的必要性。

In recent years,along with city expansion and satellite town construction,suburban rail lines have become an important development direction of rail transit.Considering the features of suburban lines being far away from the city stations,authors studied the design for water supply,in particular,the option of fire-proofing water supply design for these lines and put forward a design idea that coordinates and optimizes water source program according to the short-and long-term water conditions around the station.They emphasized the necessity of setting fire-proofing water pools,fire-proofing car intakes,outdoor fire-proofing hydrant pipeline network and compression facilities in order to ensure the self-reliance of remote stations.
