高层建筑消防给水系统的设计与应用

Design and application of fire water supply system for high-rise buildings

为解决传统消防给水系统在高层建筑中适配度较低、应用范围受限、灭火可靠度不高的问题,开展对消防给水系统的重点研究。通过选取消防给水系统组件配置、计算高层建筑最不利点消火栓给水压力、基于高层建筑结构布置水泵吸水管,设计了一种全新的适用于高层建筑的消防给水系统。通过实例应用分析可知,新的消防给水系统应用后,各组件运行状况均满足高层建筑火灾灭火需求,且在火灾危险源面积逐渐扩大的趋势下,灭火所需消防用水量较少,具有较高的可靠性与经济性。

In order to solve the problems of low adaptability,limited application range and low fire extinguishing reliability of traditional fire water supply systems in high-rise buildings,the key research on fire water supply systems was carried out.By selecting the component configuration of fire water supply system,calculating the water supply pressure of the fire hydrant at the most unfavorable point of the high-rise building,and arranging the water pump suction pipe based on the high-rise building structure,a brand-new fire water supply system suitable for high-rise buildings is designed.Through the application analysis of examples,it can be seen that after the application of the new fire water supply system,the operating conditions of each component meet the fire extinguishing needs of highrise buildings,and under the trend of gradually expanding the area of fire hazard sources,the fire water consumption required is less.The new system has higher reliability and economy.
