TBM Segment Injection Socket

TBM Segment Injection Sockets are specialised connection components installed within precast tunnel lining segments to provide access points for post-installation grouting and injection operations. They facilitate the controlled injection of grout or sealing materials behind tunnel segments, helping to fill voids, improve ground contact and support long-term tunnel integrity.

Manufactured from high-quality polymer materials using precision injection moulding techniques, these sockets are designed to provide reliable performance during tunnel construction and segment installation. Their robust design assists with accurate positioning and secure integration within the segment system while maintaining compatibility with tunnel grouting and injection equipment.

Available in various sizes and configurations, TBM Segment Injection Sockets can be produced to meet project-specific technical requirements and tunnel lining specifications.
