Description
Description | The National High Speed Rail Corporation Limited (NHSRCL) has lowered the cutterhead of the second Tunnel Boring Machine (TBM) for the tunnel section of the Mumbai-Ahmedabad bullet train project in Navi Mumbai. The 13.6 meter diameter cutterhead weighing 350 tonnes was lowered at Sawli near Ghansoli, marking the final step in the primary assembly of the TBM's main shield. Both TBMs will undergo final assembly and commissioning trials before excavation work begins in the first week of July. The TBMs are designed to excavate a single tunnel large enough for both up and down lines of the high-speed rail corridor, including a 7-km undersea tunnel beneath Thane Creek, India's first undersea rail tunnel. |
