破碎围岩斜井调洞施工技术

摘要

在充分分析了斜井与主洞会交处的围岩地质情况后,通过对斜井进入主洞前的支护转体调整、调洞的开挖工序、斜井主洞转体开挖等施工技术的控制,实现了斜井成功调洞。%After fully analysis the surrounding rock location situation of inclined shaft and main tunnel interchange,through the control to the supporting body adjustment before inclined shaft into the hole,adjustable hole excavation procedure,main tunnel excavation of inclined shaft and other construction technology,realized the success adjustable hole of inclined shaft.
