Large Diameter TBM Tunnelling Beneath New Reclamation

shield TBM for the northbound (N/B) and southbound (S/B) tunnels, respectively (Kwong et al., 2018). The 4.2 km sub-sea tunnels and the 450 m approach tunnels at SL were excavated using two 14 m diameter slurry mix-shield TBMs. The TBM tunnels at SL broke out into the adjacent ramp tunnels constructed using the cut-and-cover method.
