随着我国城市建设的迅速发展,城市人口密集,土地昂贵,城市的高层建筑和超高层建筑越来越多,这些高层建筑正朝着现代化、大型化、多功能化的方向发展,由于高层建筑楼层高,功能复杂,设备繁多,一旦发生火灾,火势迅猛,蔓延迅速,易形成立体燃烧,烟雾浓、毒气重,给扑救工作和人员疏散带来了很大的困难,虽然被困人员有多种逃生方法,但逃生难度大,风险也大,容易造成重大的经济损失和人员伤亡事故。Domino-Rope(DR)技术为被困人员紧急逃生提供了一种途径。
With the rapid development of urban construction in our country, densely populated cities and expensive land, there are more and more high-rise buildings and super-tall buildings in the city. These high-rise buildings are moving towards modernization, large-scale and multi-functional development. The floors are high, the functions are complex and the equipments are numerous. Once a fire breaks out, the fire is in a rapid fire and spread rapidly. It is easy to form a three-dimensional combustion system. The thick smoke and heavy gas poisoning bring great difficulties to the rescue work and personnel evacuation. There are many kinds of escape methods, but they are difficult to escape and risky, which can easily lead to major economic losses and casualties. Domino-Rope (DR) technology provides a way for emergency evacuation of trapped personnel.
