特长高速公路隧道内由于爆破作业、机车尾气、瓦斯、一氧化碳、硫化氢等有毒有害气体污染洞内空气,存在大量安全隐患,隧道通风是防止有毒有害气体危害的最根本措施。利用新鲜空气将有毒有害气体稀释到安全浓度以下,并将有毒有害气体排出作业空间。本文主要探讨特长高速公路隧道高效通风的施工管理与控制。
Advantages There are a lot of potential safety hazards caused by blasting operations, locomotive exhaust gas, methane, carbon monoxide, hydrogen sulfide and other toxic and harmful gases in the tunnels of the expressway. The tunnel ventilation is the most fundamental measure to prevent the harm of toxic and harmful gases. Use fresh air to dilute toxic and harmful gases below the safe concentration and to remove toxic and harmful gases from the work space. This article mainly discusses the construction management and control of the expressway ventilation tunnel.
