大相岭隧道通风斜井施工方案优化

Construction Scheme Optimization for Inclined Ventilation Shaft of Daxiangling Tunnel

针对进场便道险峻、洞口地形狭窄、斜井坡度陡的原通风斜井设计施工方案,通过现场详细踏勘、多方面的方案比对,对原设计施工方案进行优化,将斜井坡度减少,变有轨运输为无轨运输,实现了"安全、环保、优质、经济、快速"的建设管理目标。

In view of the original designed tunnel entrance inclined ventilation shaft construction scheme in the condition of steep temporary road,narrow entrance terrain and steep inclined shaft slope,through field reconnaissance and scheme comparison between many aspect,Optimization to the original designed construction scheme has been worked out,which has reduced the grading of the inclined shaft slope,changed the track transportation into trackless transportation,with the goals of ＂ safety,environmental protection,high quality,economy and fast＂ being achieved.
