The demand for underground construction is increasing worldwide. Tunnel boring machines are nowadays widespread for tunnels and the connection with the surface remains a challenge in poorly consolidated materials. Key technologies in development in the sector are related to automation, data driven artificial intelligence to guide the system and control energy consumption, laser positioning and inspection, monitoring key indicators and navigating through diverse geological conditions.
Key challenges in a nutshell
- Identification of rock properties ahead of the tunnel front based on sensors and data driven artificial intelligence AI
- Real-time steering of TBM based on monitored data and artificial intelligence AI
- Technologies to prevent TBM to be stuck
