Cross Rail Construction

Cross Rail Construction VHS Hydraulic Domplete Hydna auodu The Cross Rail development situated in the London Underground is one of the largest construction projects in Europe. The transport infrastructure has engineered immense tunnel boring machines, which heavily rely on hydraulic components to construct the rails beneath London. 40 metres 8 TBM's down in depth. (Tunnel Boring Machines) are tunnelling new rail tunnels under London. The tunnel journey will: & Replace with sealed concrete Remove ground The length of themachine is equivalent to nearly 14 red London buses! 7.1 metre diameter The speed of the rotating cutter head is up to 3.19 rotations per minute. It would take the same force to lift 2,900 London taxis equivalent to the push force of a tunnel boring machine The TBM is steered with precision by 10 hydraulic rams. Hydraulic cylinders are retracted & extended to place & secure concrete segments. X 250,000 segments of concrete will be used to Line 21 km of the twin-bore tunnels. Each tunnel boring machine is operated by a "Tunnel Gang' of 20 people.
