Final fit-out of the replacement fixed equipment in the North tube of the Channel Tunnel, to complete the repair works, is slightly ahead of the programme set down by owner and operator Eurotunnel after the shuttle train fire on 11 September last year.
A 650m section of the tunnel required repairs, the worst damage being over a stretch of 550m. Hydrodemolition was used to helped clear the damaged concrete segmental lining and prepare it for shotcreting once exposed reinforcement was fixed.
Access to the fire-damaged tunnel, which resulted in the temporary operational loss of one third of the North tube, was only possible from mid-October. The main civils works finished ahead of schedule and the lead was kept by the electro-mechanical fit-out activities
