KANPUR (Metro Rail News): On Sunday, Tunnel Boring Machine (TBM) S93 achieved a breakthrough at the Bada Chauraha Station, marking its third successful tunnel breakthrough in the ambitious Kanpur Metro Phase 1 project. The TBM completed the construction of the up-line tunnel from Naveen Market to Bada Chauraha, spanning approximately 510 meters. This accomplishment is part of the larger plan that involves a total of 8 breakthroughs in the 3.619 km Package KNPCC-05 section, which connects the Permat Ramp to Nayaganj Station.
The TBM responsible for this feat is the Terratec TBM, known as “Nana” after Nana Saheb Peshwa, with a diameter of 6.52 meters and a length of 120 meters.
The Nana TBM was launched at the New Market Metro Station on July 15, 2023. In just 57 days, the Nana TBM completed the task of installing 362 rings and reached the 510-meter long ‘up-line tunnel’ at Bada Chauraha. Now, this TBM will be removed from the Bada Chauraha Metro Station and lowered at the launching shaft at MacRobertganj.
Additionally, another TBM, ‘Tatya’ is also deployed in the construction of the ‘down-line’ tunnel between New Market and Bada Chauraha. So far, this TBM has completed the construction of approximately 300 meters of tunnel, involving the installation of 210 rings. The tunnel construction work will be completed soon. On the other hand, preparations are underway to launch the fourth TBM to create an underground track from Kanpur Central Station to Nayaganj.
