Abstract: To address TBM jamming caused by large deformation in high-stress soft rock tunnels, this study takes the Xinjiang XEⅢ project as a case to analyze the primary causes of TBM jamming accidents. The results clearly indicate that soft rock deformation is the main factor delaying the construction progress of the remaining 2.3 km section. Accordingly, a comprehensive technical solution of omni-directional and normal anchoring with long, rapid and strong features behind the TBM cutterhead is proposed, and a TBM-mounted omni-directional and normal deep anchor hole drilling machine is developed. The equipment incorporates a swing arm-feeding beam linkage adjustment mechanism (angle adjustment accuracy ±0.5°) and a compact drill rod clamp module (50% volume reduction),enabling 360° normal drilling of system deep anchor holes (8-12 m depth) within a confined 2.4 m annular space.The modular rod connection technology improves drilling efficiency to 1 m/min. Field applications demonstrate that this technology can achieve omni-directional and normal deep anchor hole drilling under TBM working conditions,reducing the anchoring cycle from 800 min/ring to 300 min/ring.
