摘要

Tunnel lining segment (1) of generally rectangular configuration having two opposite edges (3) arranged in use to face axially of the tunnel lining, and the alternate two opposite edges (2) arranged in use to face circumferentially of the tunnel lining, the segment being curved in the circumferential direction concave inwardly; supporting and connecting flanges (4-7) extending inwardly of the segment adjacent the circumferentially facing edges thereof; at least one of the flanges being provided on its outer surface with a finger (13,14) extending inwardly of the flange and arranged to engage with a circumferentially facing flange on a adjacent segment during assembly of a lining ring; and the finger being formed of material which is plastically deformable on the application of pressure thereto.
