Having the correct support systems in place for tunnelling machines, information handling and segment liner systems is crucial for such a massive undertaking. TUnIS.mono cam, our assistance system for double shield TBMs, has been involved in Sydney Metro City and Southwest and will also be used for the upcoming projects Sydney Metro West & Western Sydney Airport.
Determining the position of the front shield on a double shield machine has traditionally been a pretty complex undertaking, involving lasers, laser targets, inclinometers and cylinder stroke measurement systems, multiple sensors and complicated cabling. In contrast, TUnIS.mono cam works with only one single active component.
How does it work? Using automatic marker recognition and image evaluation, TUnIS.mono cam determines…
- The absolute position and situation of the gripper shield
- The position and situation of the front shield in relation to the gripper shield
From the combination of both datasets, the absolute data of the front shield is calculated
