Short description: World's largest tunnel boring machine, used for Hong Kong road infrastructure
The Tuen Mun - Chek Lap Kok TBM is the world's largest tunnel boring machine launched in June 2015 by Herrenknecht in Germany. The TBM is used to drill a 5 km tunnel connecting Tuen Mun to the Hong Kong International Airport, part of the Tuen Mun–Chek Lap Kok Link project. The machine has a diameter of 17.6 metres (57.7 ft),[1] 0.1 metres (0.3 ft) more than Bertha, the previous largest tunnel boring machine.[2][3]
Operations
The machine will excavate a 5 km-long underwater tunnel, working at pressures as high as 5 bars. The drilling will take place in depths of up to 50 m below sea level.[4]
