隧洞施工洞内深孔注浆加固施工技术

On grouting and reinforcement technique of in-tunnel deep hole in tunnel construction

以南干渠十二标工程施工为例,通过探讨洞内深孔注浆加固技术在隧洞工程下穿建筑群施工中的实施技术,提出相应的施工技术控制要点,旨在为同类隧道工程提供实例参考。

Taking Nanganqu No. 12 Project as the example, the paper explores the implementation technique of the grouting and reinforcement technique of in-tunnel deep hole in tunnel construction in the tunneling architectural complexes of the tunnel project, and points out the respec- tive controlling points of the construction technique, so as to provide the example reference to the similar tunnel projects.
