公路瓦斯隧道施工通风技术研究

Research On Ventilation Technology of Highway Gas Tunnel Construction

随着我国公路施工技术标准的不断提升,隧道工程所占比例越来越大,由于隧道本身地质条件的复杂性,在其掘进过程中,常会遇到甲烷、一氧化碳、硫化氢等有毒有害气体的出现。如果没有一套完整的、合理的、专业的瓦斯隧道专项通风方案来解决现场通风情况,则很有可能造成局部瓦斯积聚、一氧化碳异常,从而造成严重的安全责任事故。因此,我们需要高度重视该类问题,提高瓦斯隧道通风技术,确保整个工程能够顺利进行。

With the continuous improvement of highway construction technical standards in China,the proportion of tunnel engineering is becoming larger.Due to the complexity of geological conditions of the tunnel itself,in the process of excavation,methane,carbon monoxide,hydrogen sulfide and other toxic and harmful gasesare often encountered.If there is not a complete,reasonable and professional special ventilation scheme for gas tunnel to solve the site ventilation situation,it is likely to cause local gas accumulation and carbon monoxide abnormality,resulting in serious safety liability accidents.Therefore,we need to attach great importance to this kind of problems,improve the ventilation technology of gas tunnel,and ensure the smooth progress of the whole project.
