50 mm消防水带在建筑火灾中的应用探讨

Application of fire host with inside diameter 50 mm in building fire

针对50 mm消防水带在建筑火灾扑救中的应用进行探讨。通过计算、比较、测量等方法,对比了50 mm和65 mm水带的性能参数,研究了50 mm水带在操作人员数量、火场供水、灭火负荷、操作便利、水带损耗和人员安全等方面的优势,同时分析了50 mm水带在阻抗系数、供水强度和垂直铺设方面的弱点。结论指出,消防救援队伍在扑救建筑火灾中,应将50 mm水带作为主要支线水带进行应用和普及,使灭火救援行动更加优化,确保灭火救援安全。

This article discusses the application of 50 mm fire hoses in building fire fighting.Through calculations,compari⁃sons,and measurements,the performance parameters of 50 mm and 65 mm hoses are compared.The advantages of using 50 mm hoses in terms of the number of personnel,fire water supply,fire extinguishing load,ease of operation,hose loss,and personnel safety are studied.Meanwhile,the weaknesses of 50 mm hoses in terms of impedance coefficient,water supply intensity,and verti⁃cal laying are analyzed.The conclusion points out that firefighting and rescue teams should use and popularize 50 mm hoses as the main branch hoses in extinguishing building fires to optimize fire⁃fighting and rescue operations and ensure safety.
