桥梁和建筑的辉煌已渐渐逝去,21世纪是地下的时代。随着国民经济和交通建筑事业的发展,各种用途和功能的地下工程数量将越来越多,规模也将越来越大。但这些构筑物都处于地下或水下的封闭空间,所以一旦发生火灾等突发情况,由于隧道内升温快、结构容易破坏、不利于救援和灭火等特点,将会造成非常严重的事故。所以,隧道等地下工程需要良好的防火措施和保障,否则可能会对工程建筑和公众的生命财产带来毁灭性的灾害。而随着我国建筑业的快速发展,各种防火技术层出不穷,在对隧道消防中也有不同的作用,本文则主要简单介绍防火涂料和防火板的特性以及施工工艺等。
The glories of bridges and buildings have faded away. The 21st century is an underground era. With the development of the national economy and transportation construction, the number of underground works of various purposes and functions will be more and more and the scale will also be larger and larger. However, these structures are all enclosed underground or under water. Therefore, once an emergency such as fire occurs, it will cause very serious accidents due to the rapid warming in the tunnel, the structural damage, and the unfavorable rescue and fire extinguishing. Therefore, tunnels and other underground works require good fire prevention measures and security, or they may cause devastating disasters to the life and property of the engineering buildings and the public. With the rapid development of China’s construction industry, various fire prevention technologies emerge in an endless stream, which also play different roles in tunnel fire fighting. In this paper, the characteristics of fire-retardant coatings and fire-proofing boards as well as construction techniques are briefly introduced.
