TBM Segment Pin Socket

TBM Segment Pin Sockets are precision-engineered components used in tunnel segment lining systems to receive and secure segment joint pins during assembly. Installed within precast concrete tunnel segments, they assist with accurate alignment, positioning and connection of adjacent segments, helping maintain ring geometry and installation accuracy throughout TBM operations.

Manufactured from high-quality injection-moulded polypropylene or equivalent engineered polymers, pin sockets are produced to the required hardness and performance characteristics specified for each project. Designed for reliable engagement with segment joint pins, they support efficient segment installation while accommodating the demanding conditions encountered in underground construction.

Available in various configurations and dimensions, TBM Segment Pin Sockets can be manufactured to suit specific segment designs and project requirements.
