随着我国国民经济的飞快发展,高层建筑日益增多,城市的小型汽车每年都在迅猛的增加,因此,为了解决汽车存放和城市用地日益紧张的问题,高层建筑地下汽车库的这种建筑类型就应运而生。高层建筑地下车车库一般为一层到三层,基本上都处于半封闭的状态,汽车进入地下车库后会排出一些废气,如果不能及时排除这些废气,将可能会引发火灾。 With the rapid development of China’s national economy, high-rise buildings are increasing, and small cars in cities are increasing rapidly every year. Therefore, in order to solve the increasingly tense problem of car storage and urban land use, this type of building in underground garages of high-rise buildings is Came into being. High-rise buildings Underground garages are generally one to three floors, and they are basically in a semi-closed state. When cars enter an underground garage, they emit some exhaust gas. If these exhausts cannot be eliminated in time, fires may occur.
