The Fullround Shutter completed its work at the Hammersmith Connection Tunnel.
The Machine was equipped with several innovations such as the Automatic Spud-bars and the first PLC system able to control all the movements of the machine in semi-automatic and full-automatic mode.
These improvements in the tunnelling industry and the secondary lining process together with the hydrostatic design, allowed to reach a great production rate of 1 block per day.
The system was also designed to be used in two different geometries and therefore optimize project costs.
The project was also presented at the British Tunnelling Society.
This was the first secondary lined tunnel on the Tideway project.
