结合超限高层建筑的消防特点,以灭火系统选择的节能减排、环保为基础,以灭火安全性、适用性和经济性为目标,提出在超限高层建筑中宜采用高压细水雾灭火系统。根据某超限高层建筑大厦的设计实例,对其灭火系统的方案进行了介绍,并从技术和经济的角度进行了分析比较。得出高压细水雾灭火系统在超限高层建筑中应用是可靠、适合的,可大大节省投资。同时,也指出了应用高压细水雾灭火系统需要考虑的问题。
Combining with the fire-fighting characteristics of over-limit high-rise buildings and taking the energy-saving and emission-reduction and environmental protection selected by the fire extinguishing system as the targets, the author puts forward that the high-pressure water mist extinguishing system should be adopted in the overlimit high-rise buildings with fire extinguishing safety, applicability and economy as the goal . According to the design example of an overstory high-rise building, the scheme of its fire-extinguishing system is introduced, and the technical and economic aspects are analyzed and compared. It is concluded that the application of high-pressure water mist extinguishing system in over-limit high-rise buildings is reliable and suitable, which can greatly save investment. At the same time, also pointed out that the application of high pressure water mist fire extinguishing system needs to be considered.
