巷道式通风方案在大梁峁特长公路隧道中的应用

Application of Drift-Type Ventilation Scheme in Daliangmao Extra-Long Highway Tunnel

随着我国隧道施工工艺的成熟,长大及特长隧道越来越多。结合具体工程,介绍巷道式通风技术及其使用效果。实践证明,该技术能保证隧道内空气质量,并大大减少一次性投入,降低运营成本。

With the development of China′s tunnel construction technology,there appears more and more long and extra-long tunnels.Combined with specific project,this paper introduces drift-type ventilation technology and its application effect.The practice shows that this technology can ensure the air quality inside the tunnel,significantly reduce the one trial investment and operating costs.
