VMT continues its innovation
drive in microtunnelling Launch of a new assistance system for automated control measurement
In 2020 VMT launched the TUnIS Navigation MT, which for the first time, combined machine guidance with laser and target, hydrostatic level, gyroscope as well as moving laser total station tunnel navigation systems into one product.
The TUnIS Navigation MT system guarantees the greatest possible flexibility and efficiency when managing projects. Up to now, when using navigation system for curved and long- distance drives (gyro based or laser total station based), manual control measurements were necessary to maintain the accuracy of the alignment (typically, a traverse measurement from the launch shaft through the pipeline up to the machine is measured manually and reference points then determined which are used for the calibration of the navigation system).
This has become particularly problematic with the growth in the requirement for, longer drives in critical diameters of ≤1,200 mm, in the Microtunnelling and Direct Pipe tunnelling sectors where entry of personnel into the pipeline is difficult or even not allowed. Pipe jacking or Direct Pipe projects with pipe or pipeline diameters of ≤1,200mm and demanding alignments (straight lines >400 m or curved routes) can only be navigated with a gyro system. Manual control measurements, which are necessary for the calibration of the gyro systems and thus for
