摘要
针对包家山特长公路隧道3#斜井工区钻爆法开挖、斜井有轨提升、正洞无轨运输、多作业面同时施工的特点,在分析研究的基础上,确定了具体的施工通风方案。现场应用测试证明,通风效果良好,通风方式合理有效。
The mode of excavation by drill and blast method, rail-bound transportation system in the inclined shaft, trackless transportation system in the main tunnel and working at multiple faces is adopted in No. 3 inclined shaft working lot of Baojiashan super-long highway tunnel. The construction ventilation scheme for the working lot is determined by analyzing the actual conditions of the working lot. The scheme is executed in the construction and good ventilation effect has been achieved, which demonstrates that the ventilation scheme adopted is reasonable and feasible.
