在消防供水系统中,高层建筑的消防水罐通常建在顶部,在一般情况,利用其水位的自然落差压力,就可出水灭火,简单且方便,但是这种水罐一旦遇到地震、战争等非常情况,就会因水罐壁破损,水管断裂,而使消防供水系统瘫痪。 1995年1月17日的阪神大震灾中,同时发生300多起火灾,由于电厂停电,水厂停水,使灭火工作很被动,同时65万户居民的生活用水没有着落。所幸神户市的121个消防队,每个消防队都有1个地下耐震性贮水槽,同时许多单位也有这样的耐震性贮水槽,对解决地震灾后的消防用水
In a firefighting water supply system, the firewater tank of a high-rise building is usually built at the top. Under normal circumstances, the natural water pressure of the water level can be used to extinguish the fire. It is simple and convenient, but once the tank encounters earthquakes, wars, etc. In exceptional circumstances, the fire water supply system will be paralyzed due to the damage of the tank wall and the breakage of the water pipe. In the Great Hanshin Earthquake on January 17, 1995, more than 300 fires occurred at the same time. Because of the power outage of the power plant, the water plant stopped water, making the fire extinguishing work very passive. At the same time, the domestic water consumption of 650,000 households did not settle. Fortunately, the 121 fire brigades in Kobe City each have an underground shock-resistance water storage tank, and many units also have such shock-resistant water storage tanks to solve the fire water after the earthquake.
