HOOPS AND RINGS PUT TUNNEL IN A WATERPROOF SHEATH

The article describes the Goldsheath system of tunnel lining which makes use of a system of barrel hoop supports on the outside of concrete segmental tunnel lining rings. It is claimed that the lining system overcomes the limitations of previous linings and can be used with present day tunnelling techniques. The lining system is based on concrete segments expanding into an external restraint sheath or flexible hoop support system. The restraint hoops are wider than the segment rings and so overlap forming a continuous, waterproof sheath. /TRRL/
