超高层建筑给排水消防设计

Design on fire water supply of super high-rise building

以天津某超高层建筑为例,介绍消防给水系统设计思路。根据不同消防系统的用水量计算,对两种设计方案进行比较,通过临时高压消防系统和重力供水消防系统的结合,利用中间水箱的转输与减压作用,对消防系统进行合理分区,增加消防系统的安全性。介绍临时高压消防系统和重力供水消防系统的控制原理,总结超高层建筑消防给水系统设计特点。

A supper high-rise building in Tianjin was selected as ex?ample to introduce the design idea of fire water supply system. Based on the calculation of fire water consumption of each fire pro?tection system, two design plans were compared. With the combi?nation of temporary high pressure system and gravity water supply system, by the transfer and decompression of middle water tank, the fire protection system was divided into different partition rea?sonably to enhance the reliability of fire protection system. The control principle of temporary high pressure system and gravity wa?ter supply system was introduced and the features in design of fire water supply system in supper high-rise building were summarized.
