The 3D concrete printing removes the need to develop logistical plans that are usually expensive. HS2’s London tunnels contractor Skanska Costain Strabag joint venture (SCS JV) is set to deploy on-site 3D reinforced concrete printing technology, Printfrastructure, for Britain’s new high-speed rail network.
This initiative is said to be the first such development where 3D concrete printing will be deployed. SCS JV will build structures on-site by printing concrete with computer-operated robots. This will replace the activity of carrying the structures as pre-cast slabs by road before assembling and lowering them into place by large cranes. The 3D concrete printing eliminates the need to develop costly logistical plans. Claimed to be a flexible mobile technology, it can be used in physically restricted areas.
