大梁隧道平导快速掘进施工配套技术

摘要

Taking Daliang tunnel drilling construction as an example,through analyzing original design and construction condition of parallel adit section,the original parallel adit design section and construction supporting machinery are optimized.As a result,single-end 4 700 m excavation,main hole ventilation and drainage problems are solved,which effectively plays the role of auxiliary adit.%以大梁隧道掘进施工为例,通过分析平导断面原设计施工情况,针对原平导设计断面及施工配套机械进行了优化,优化后解决了独头开挖4 700 m、正洞通风、排水问题,有效发挥了其辅助坑道作用。
