Tunnel Lining TRIZ Cases
- Slipform Blade Foot With Hydraulic Pre-Compression for Shaft Wall Sealing
Hydraulic arc-plate displacement applies controlled pre-compression to shaft wall concrete, improving compactness and preventing water-conducting cracks.
- Zonal Bolt-Grouting Support for High-Stress Tunnel Deformation
See how prestressed bolts, zoned grouting, and expansion agents stabilize cataclastic rock in high-stress tunnels.
- Shield Machine Entrance Sealing Method
A shield method uses cylindrical frames and sealing members to seal the shaft entrance during tunnel excavation.
- Lateral Rotary Positioning Mechanism for Child Carrier Stability
An elastic restoring element pushes an engaging pin into a recess on the base, locking it in a lateral position to prevent unwanted movement.
- Shield Construction Stratum Deformation Control
A shield construction method monitors settlement parameters to predict deformation proportions and adjust operational settings in real time.
- Counter-Rotating Disk Drill for Brittle Soil Tunneling
Adjacent disk drills rotate in opposite directions to cancel torque, preventing soil collapse and rupture in brittle coral reef formations.
