浅谈注浆工法在处理隧道塌方中的应用

On the application of grouting technique in the treatment of the tunnel collapse

在处理浅埋段隧道冒顶塌方时,提出了地表采用劈裂注浆技术和洞内采用迈式锚杆双液浆施工技术加固相结合的方法,对其施工技术要点作了论述,保证了开挖进度和断面尺寸符合相关计划和规范的要求。

In the process of treating the shallow tunnel collapse and the roof cave-in tunnel collapse, the paper points out the fracturing grouting method and the stepping-style slip casting double liquid technique can be applied on the ground surface, and illustrates the technique points in order to ensure the excavation process and the cross-sectional dimensions to meet the requirements of some related rules and regulation.
