Abstract (en)
[origin: EP1201876A1] The lining for a tunnel is made up of rings of curved blocks (10,20) arranged along the length of the tunnel. The blocks are each provided with tongue and groove interlocking formations (14,24;18,28) on their edges so that the rings are connected and locked against peripheral movement, while allowing radial movement. The formations can have locking inserts.
