The bullet train will consist of a 21km long tunnel between the underground station at Bandra-Kurla Complex and Shilphata in Maharashtra. (express photo) A tunnel boring machine (TBM) with a 13.1 metre wide cutter head will be used to dig India’s first undersea rail tunnel as part of the Mumbai Ahmedabad Bullet train project. Previously, the largest TBM deployed in the country was 12.2 metre wide that was used for digging tunnels for Mumbai’s coastal road project.
The bullet train will consist of a 21km long tunnel between the underground station at Bandra-Kurla Complex and Shilphata in Maharashtra.
The tunnel will be a single-tube tunnel to accommodate twin tracks for up and down movement of trains. Thirty-nine equipment rooms at 37 locations will also be constructed, adjoining the tunnel location as part of the package.
The TBM with 13.1 metre wide cutter head will also be used to dig a 7km stretch at Thane Creek under the sea level. A total of three TBMS will be deployed for the purpose.
The tunnel will be about 25 to 65 metres below the ground level. Three shafts at BKC, Vikhroli, and Sawli in Thane at approximate depths of 36m, 56m and 39m will facilitate construction.
The National High Speed Rail Corp. Ltd (NHSRCL), a special purpose vehicle (SPV) formed for the construction of the bullet train project, has inked an agreement with M/s Afcons Infrastructure Ltd to construct the 21-km stretch, which includes the 7-km-long undersea rail tunnel.
