We could drill 'cores' through the concrete lining and into the rock up to a depth of 1metre. We would then insert a steel pipe and grout it into position. The maximum finished internal diameter is approx. 75cm.

Assuming no services need to be diverted, no water ingress problems, and the core is at around 1metre above the tunnel floor, an approximate budget cost is :13,000chf per hole = 24no. * 13k = 312,000chf.
