Tunnels excavation using Tunnelling Boring Machines has significantly consolidated in recent years.
One of the most serious challenges that have proved most difficult to deal with is the crossing of the reinforced concrete structures of launching and recovery shafts as well as stations built along the TBM route.
SIREG has developed a series of products particularly useful in solving this problem, allowing the progress of the tunnel excavation with TBM quickly, safely and cost effectively.
