某历史名镇消防给水设计分析

Fire water supply capability calculation of a historic town

结合云南易武古镇消防给水现状,运用水力计算的方法对室外消防给水的设置进行计算分析,提出了古镇消防规划中文物保护建筑的消防用水需求问题。对该古镇消防给水系统的设计给水能力提出以被保护文物建筑1次灭火的消防用水量为基准,考虑文物建筑的保护价值、耐火等级、毗连建筑等实际情况,运用消防用水量标准、消防给水管网管径和消防给水压力等基础资料,计算分析古城镇消防给水系统给水设计能力,最大限度提高古城镇的消防用水可靠性。

Combing with the fire water supply situation of Yiwu town, the outdoor fire water supply setting was calculated using hydraulic calculation, and the fire water requirement of cultural rel- ic building in ancient town fire protection plan was given. It was suggested that the fire water supply capability should be based on the water volume putting out one fire, and should consider the pro- tection value, fire rating and adjoining building. Using fire water consumption standard, fire water supply network diameter and fire water pressure, the fire water supply capability of the historic town was calculated, to improve the fire water reliability of the town.
