There are two separate divisions of concrete lining methods: in soft ground tunnels, and in rock tunnels. In soft ground tunnels, concrete lining must be placed immediately after the excavation of a short advance, whereas in rock tunnels the lining operation can be deferred until driving is complete. This paper deals with the special problems of in-situ concrete lining in rock tunnels, with particular reference to the concrete lining carried out in the Derwent-Wear-Tees tunnels, part of the Kielder Water Scheme in north-east England. It discusses rate of advance, concreting equipment, concrete mix, grouting, and other aspects of the subject.
