超高层建筑室内消火栓系统设计方案探讨

Discussion of indoor fire hydrant system design in high-rising buildings

结合一个典型超高层建筑实例,设计了四种国内通常采用的并联分区系统、减压阀减压分区系统、串联分区系统及高位消防水池分区供水系统设计方案,并以安全可靠性、经济性、适用性作为设计方案的选用标准,对各种设计方案的组成、特点、系统设计要求进行了分析、对比研究。结果表明:超高层建筑在建筑高度不超过消防水泵一次供水高度且系统管网内任何时间、地点压力不超过2.4MPa的情况下,应优先选用并联分区供水系统。

Taking a typical high-rise building for example,we designed four frequently used domestic indoor fire hydrant systems including typical parallel partition scheme,valve decompression partition scheme,series partition scheme and the roof fire fighting water pool scheme.Using safety and reliability,economy,applicability as selection principle of different schemes,this article analyzed and compared composition,characteristics and system design requirements of different design schemes.The results approve that typical parallel partition scheme is the first choice when the height of high-rise buildings is not taller than that of fire hydrant water supply and the pressure inside fire hydrant system pipeline network is below 2.4MPa.
