摘要
对建筑高度大于250 m民用建筑室内消防给水的典型竖向供水方式进行了分析和讨论,以提升消防给水的安全性和提高系统供水能力为原则,提出了采用临时高压消防给水系统和高压消防给水系统两组独立系统并联供水的竖向布置方式,以建筑顶部和底部的水源双向同时向室内消防给水各竖向分区系统供水。以实际工程设计为例,详细分析和探讨了设计案例中双水源双向并联供水方式的运行特点,以及供水设施、管道的竖向布置等关键设计环节及其对消防供水安全的影响。
Through analyzing and discussing typical designs of water supply in vertical for fire protection water supply systems in civil buildings over 250 m high,a vertical layout mode of double fire water sources system is presented.In this mode,a constant high pressure fire protection water supply system provide fire water from the top of the building and a temporary high pressure fire protection water supply system provide fire water from the bottom simultaneously,independently,in parallel way.A practical engineering designed in this mode is presented in the paper,through which some key factors in designing are discussed,including vertical layout of water supply facilities and pipe systems.
