高速公路隧道穿越多方向断裂带和围岩极度破碎易坍方路段 ,采用超前注浆及拱顶、边墙、底部注浆工艺 ,解决了隧道洞身开挖、二次衬砌加固的难题 ,确保了隧道的使用安全。
The highway tunnel passes through the multi-directional fault zone and the surrounding rock crushers the collapsible and easily collapsing sections. The advanced grouting, vault, side wall and bottom grouting process are adopted to solve the problems of tunnel excavation and secondary lining reinforcement and ensure that Tunnel safety.
