Segment Production System
The Tunnel Segment Production and Handling System is an integrated industrial solution dedicated to fabricating high-strength precast concrete lining segments that form the permanent structural shell of TBM-driven tunnels. The complete automated workflow encompasses precision steel mold assembly, concrete casting, accelerated steam curing, demolding, yard storage, and vacuum-assisted transport logistics into the tunnel.

- Key Features & Benefits
- Heavy-duty precision-machined steel molds maintain tight ± 1 mm ±1 mm dimensional tolerances, ensuring flawless ring alignment and zero structural mismatch.
- Automated carousel and stationary lines deliver high production rates of 20 to 120 complete rings per day to seamlessly match rapid TBM advance rates.
- Dedicated vacuum lifters and gantry crane systems handle fresh and cured concrete segments safely without chipping edges or damaging sealing gaskets.
- Accelerated thermal curing cycles (8 to 24 hours) maximize mold turnaround time while achieving high early-age concrete strength.
