某超高层建筑消防水系统设计探讨

The Probe into the Fire Water System Design in a Super High-rising Building

结合对某超高层项目消防水系统的分析,探讨了超高层建筑消防系统的给水补水形式、系统减压、灭火设施的选择及湿式报警阀的设置等问题。建议超高层建筑消防给水设计优先考虑设置高位水池的常高压给水系统;以重力形式供水的湿式自喷系统可通过加强水流指示器和信号阀的报警功能,取消湿式报警阀的设置。

Based on the analysis of a fire water system design in a super high- rising building,this paper probes into the ways of supplying fire water and replenishing systems,pressure reducer systems,the setting of wet alarm valves and choices of a fire extinguishing system,etc. It is recommended that the high gravity pool partition supply system for its fire prevention system design should be used in a super high- rising building instead of a sprinkler system by enhancing the alarm function of water flow indicator and signal valve.
