Abstract

1,257,732. Tunnels &c. Y. TSUZUKI. 2 Jan., 1969 [4 Nov., 1968; 10 Dec., 1968], No. 353/69. Heading E1F. A joint between tunnel segments 1 is sealed by placing a seal comprising bitumen 5 and an electrical heating element 4 in the joint, supplying current to the element to melt the bitumen, and discontinuing the supply to permit the bitumen to harden. Elements are coated with bitumen to form rods or strips which are housed in one or both grooves 3 of abutting segments prior to assembly of the segments. Fig. 8 shows one segment having a groove 9 and the other a projection 10, the seal being housed in the groove 9 prior to assembly of the segments.
