TBM Segment Joint Pin

TBM Segment Joint Pins are precision-engineered components used to align, locate and secure precast tunnel lining segments during assembly. Installed between adjacent segments, these pins assist with accurate positioning, improve ring geometry and help maintain segment alignment throughout installation.

Manufactured from high-quality injection-moulded polypropylene or equivalent engineered polymers, segment joint pins provide reliable performance in demanding tunnelling environments. The design enables secure engagement between matching sockets while allowing efficient segment installation during TBM operations.

Produced to project-specific technical requirements, segment joint pins can be supplied in various sizes, configurations and material grades to suit different tunnel lining systems and segment designs.
