摘要
文章结合叙大铁路乐园隧道工程实例,根据其辅助坑道布置和瓦斯分布等工程特点,确定了独头压入式和巷道式通风相结合的施工通风方式,并通过对需风量、风机供风量、风管阻力和隧道阻力的计算,对通风设备进行了优化配置,同时提出了隧道施工通风方案设计过程中需考虑及注意的问题,为类似铁路瓦斯隧道施工通风设计提供参考。
In combination with the engineering practices of Xuda Railway Leyuan Tunnel,and according to the layout of its auxiliary tunnel and the gas distribution and other engineering characteristics,this ar-ticle determined the construction ventilation method combining the single head pushing and laneway ventilation,and through calculating the required amount of wind,wind supply amount of fans,windpipe resistance and tunnel resistance,it conducted the optimization configuration on ventilation equipments,and proposed the problems to be considered and noted during the tunnel construction ventilation pro-gram design,thereby providing the reference for the gas tunnel construction ventilation design of similar railways.
