Week 20 & 21 Tunnelling & TBM Course: Tunnel Facilities and Quality

Week 20 and 21 (2nd June to 13th June) of the specializing course on Tunnelling and TBM covered the design aspects of the following Auxiliary Tunnel Facilities:

• Underground Railway Transportation (Rails, Rolling stock and Locomotives)
• Underground Ventilation System [1] [3]
• Conveyor Belts
• Compressed Air
• Separation Plant for Slurry Shield [2]
• Water Treatment Plant [2]
• Lighting [1]

Above design aspects were discussed by the designers from the leading industry suppliers (Atlas Copco, Swedvent, Marti Technik) and contractors (Salini Impregilo).

Mr. Marco Arato from Atlas Copco - Lecture on Locomotives and Ventilation

Mr. Antonio Nicola - Overview lecture on Auxiliary Tunnel Facilities

Prof. Oggeri (also the Animateur of WG 16 : Quality in Tunnelling), discussed about the recommendations on how to achieve Quality in Tunnelling and how to identify, evaluate and specify Quality Management measures to be taken by all parties in the Conceptual Planning, Procurement, Design, Construction, Operation and Maintenance phases of underground projects involving tunnels [4].
