铁路特长高瓦斯隧道施工通风技术

Ventilation Technique for Extra-long High-gas Railway Tunnel

良好的通风系统是保证隧道施工顺利进展的关键,特别是在高瓦斯隧道施工中,加强施工通风是稀释和排出瓦斯的主要手段,是防止瓦斯事故发生和保护施工人员身心健康的重要工序。以兰渝铁路特长高瓦斯梅岭关隧道为例,详细介绍了其施工通风技术和经验,为以后同类工程施工提供借鉴。

Good ventilation system is the key to ensure tunnel construction smoothly, especially in the high-gas tunnel construction. Strengthening the construction of ventilation is the primary means of gas dilution and exhausting, and it is also an important process to prevent gas accidents and protect the health of construction workers. Taking Lanzhou-Chongqing Railway Extra-long High-gas Meilingguan Tunnel as an example, the paper makes a detailed introduction to the construction ventilation technique and experience, and provides references for the similar projects construction in the future.
