  Early Information of Ground Conditions with SSP -E in TBM Tunnelling

  Abstract: In order to monitor the ground conditions ahead of a TBM while tunnelling, there is a need for systems that are co-working smoothly with the TBM. Sonic Softground Probing for Earth Pressure Balance Shield machines (SSP-E) is capable of early detecting obstacles relevant for TBM tunnelling and thus enables responsible persons on construction sites to react in a timely and plannable manner to...

  Energy Efficient EPB Design Applying Machine Learning Techniques

  Abstract: A significant part of the energy consumed during the tunnelling process of Earth Pressure Balanced (EPB) Tunnel Boring Machines (TBMs) is related to the main drive, consisting of a set of motors driving the rotation of the cutting wheel. An energy efficient EPB design requires the optimization of the main drive to avoid over- or under powering of the machine. Key aspect is therefore a precise...
