Research on Polymer Injection Technology for Quick Tunnel Repairment
Publication: Road Pavement Material Characterization and Rehabilitation: Selected Papers from the 2009 GeoHunan International Conference
Abstract
Aiming at existing void between initial lining and surrounding rock or initial and secondary lining, with ground-penetrating radar nondestructive testing technology and polymer grouting technology, the article has attempted to study the polymer grouting technology of tunnel maintenance. Taking an under construction highway tunnel as a test section, the tunnel lining has been tested with ground-penetrating radar, and the disease scope of the tunnel has been determined, the detected void region has been treated with polymer grouting, the grouting effect has been verified with ground-penetrating radar, the polymer grouting technology applying in treating with the disease of tunnel lining has been studied, and the tunnel polymer grouting repair technology has been initially formed. The field testing result shows that using polymer grouting technology, the tunnel damage can be treated, and a new idea for tunnel quick maintenance can be provided.
