Construction of the 21-km-long tunnel—including India’s first 7-km-long undersea tunnel—which is part of the Mumbai-Ahmedabad bullet train project has reached a crucial stage, with 100 per cent work of shaft piling at Vikhroli being completed. This shaft will be used to lower two tunnel boring machines in different directions—one towards Bandra Kurla Complex (BKC) and the other towards Ghansoli. India’s first underground/undersea tunnel is under construction for bullet train stations at BKC and Shilphata near Kalyan, which will be underground.
“Construction work has already begun at five locations. Shaft 1 is at the Mumbai HSR station construction site where the depth is 36 metres. Secant piling work is 100 per cent completed and excavation work is currently underway,” the National High Speed Rail Corporation Ltd (NHSRCL) spokesperson said. According to the official, the shaft at Vikhroli also has a depth of 36 metres and piling work has been completed, with excavation work currently underway. “This shaft will be used to lower two tunnel boring machines,” she said, adding that shaft 3 at Sawli (near Ghansoli) is 39 metres deep and excavation work has started.
