技术介绍
随着土地的严重紧缺和城市化、工业化步伐的加快，城市和工厂的各类房屋迅速由低矮型平房向高楼化方向发展，然而高频率的、梯级式的、传替式的、链锁式的、规模化的火灾却成了最大的威胁，下楼着火，上楼遭殃；而且随着第三产业的高速发展，低位楼层侧天然地成了他们耐以生存和发展的最佳选择地，然而一个高频率的火灾发源地就这样诞生了；同时随着工业化的高速发展，楼房式的生产车间铺天盖地的应运而生，又一个高频率的火灾发源地也就诞生了。这些火灾的一个共同显著特点是：任意一个低位楼层房间着火，火焰就可以在几分钟内迅猛、逐层、传替式地引燃以上楼层和左右相邻房间，浓烟更是一步登天地包裹着以上一切，严重地威胁着人们的生命和财产安全，也就在这短暂的几分钟之内，大火与浓烟无情地吞噬着上方所有房间内的人们，也就在这短暂的几分钟之内，消防队伍还在奔赴的路上，从客观上讲，一是外援总是滞后的，是根本不可能在这最关键的第一时间内挽救这些不幸的人们，二是楼房的高化速度和程度，现有消防技术和力量只能望而生叹。在现有技...
