Rapid Rescue Solutions for TBM/Shield Machines in Mountain Tunnel Construction

During the construction of long-distance mountain tunnels using double/single-shield TBMs or shield tunneling machines, complex geological hazards such as fault zones, collapse columns, mudstone/soft rock strata, foliated schist layers, and karst caves frequently trigger surrounding rock collapse. These incidents exert excessive pressure on cutterheads and shield structures, resulting in machine jamming and operational failure, ultimately preventing or severely impeding tunneling progress.
