Taixing railway’s treatment technology for tunnel collapse of Erqing mountain

介绍了隧道塌方采用大管棚超前支护注浆和小导管径向注浆相结合的方式支撑塌体,确保塌方处理安全的施工技术,为围岩破碎、地下水发育的隧道塌方处理提供了一定的经验和见解。

This paper introduces that collapse body is supported by the combination of large pipe shed support grouting and small pipe radial grouting,in order to make sure the landslide treatment is safe.
