某既有铁路隧道缺陷整治技术

Defect Treatment Technology of An Existing Railway Tunnel

以某铁路隧道衬砌缺陷整治工程为例,简单分析了衬砌缺陷的检测,缺陷原因,并提出缺陷整治方案,包括缺陷衬砌凿除、植筋、锚杆施工、清洗界面和恢复衬砌、注浆充填加固。

Taking a railway tunnel lining defect remediation project as an example, detection of lining defect and cause of the defect are briefly analyzed, and the defect treatment scheme is proposed, including defect lining chiseling, reinforcement planting, anchor bolt construction, interface cleaning and lining restoration, grouting filling and reinforcement.
