襄陽市樊城區(qū)前進東路一景城市花園酒店發(fā)生火災(zāi)， 8 時 50 分大火被撲滅。 關(guān)鍵詞 ： 酒店 消火栓系統(tǒng) 自動噴水滅火 系統(tǒng) II Design of fire water system on sevenstory hotel ABSTRACT Hotels appear to be more and more mon in our lives with the increasing development of modern economy, acpanied by a high demand in fire extinguishing system due to the tremendous mobility of its faculty, large amount of inflammable materials in interior decoration, highly fire risks and so on. The project in this design is a sevenfloor mercial lowrise building
