As its third breakthrough in the 32.4 km Kanpur Metro Phase 1 project, the TBM Nana, which is the Gulermak – Sam India Builtwell JV’s TBM S93 with 6.52 m diameter and 120 m length and has been named after Nana Saheb Peshwa and built by Terratec, in September 2023 reached the Bada Chauraha Station. The commissioning station of this machine was the Naveen Market Metro Station and through installing 362 rings it completed building of the 510 m up-line tunnel from Naveen Market to Bada Chauraha. Currently, this TBM will be removed from the Bada Chauraha Metro Station and lowered at the launching shaft at MacRobertganj.
Additionally, digging of the down-line tunnel between Naveen Market and Bada Chauraha is up to the refurbished Terratec’s TBM EPB S92, that is 6.52 m diameter and 120 m long and named Tatya after Tatya Tope. Commencing its drive on 2023 at Nayaganj Station, now the TBM has bored 300 m of tunnel with 210 rings installed. The tunnel construction work is due to be completed soon.
As part of the larger plan, this accomplishment involves a total of 8 breakthroughs in the 3.619 km Package KNPCC-05 section, which links the Permat Ramp to Nayaganj Station.
