隧道病害整治施工中的锚固与注浆技术

Blot and Up-inject Technology in Tunnel Diseases Repairing Engineering

广东省鲘门隧道的病害整治工程采用钻孔、锚固和注浆一体化的自钻式中空锚杆锚注加固技术,改善围岩的物理力学性能,有效提高锚杆的锚固力,增强整个拱部的整体稳定性,达到隧道渗漏水整治效果,可取得良好的经济和社会效益。

The blot and up-inject technology which combines drilling,anchoring and grouting in Houmen tunnel located in Guangdong province of China successfully improved the physical and mechanical behaviors of surrounding rocks and increased anchoring forces of bolt.Meanwhile it enhanced holistic stability of vault of tunnel and solved the seepage problems effectively and had a good economic and social benefit.
