Kanpur Metro’s TBM Tatya Records 2nd Breakthrough at Naveen Market

Gulermak – Sam India Builtwell JV on Monday celebrated tunnel boring machine (TBM) S92’s breakthrough at Naveen Market Station of the 32.4 km Kanpur Metro Phase 1 project.

This was TBM S92’s second breakthrough and the 4th of 8 tunnel breakthroughs planned on the project’s 3.619 km Package KNPCC-05 connecting Permat Ramp – Nayaganj Station.

This 6.52m diameter and 120m long Terratec TBM, nicknamed Tatya after after Tatya Tope, had recorded its first tunnel breakthrough (project’s 2nd) at Nayaganj Station in January 2023 after building a 1025m long tunnel from Bada Chauraha Station.

For its second assignment, the machine was commissioned from Chunniganj Station in March 2023 to build the down-line tunnel and traveled 728m to arrive at Naveen Market Station in roughly 4 months.

Uttar Pradesh Metro Rail Corporation (UPMRC) had awarded Gulermak – Sam India with Package KNPCC-05’s construction contract in March 2021 with a 36 month deadline.

Besides constructing twin tunnels, they’ll be building 4 stations at Chunniganj, Naveen Market, Bada Chauraha and Nayaganj, each 215m long.

TBM Tatya will now be dragged through Naveen Market’s station box and recommissioned for its 3rd assignment to build a 516m tunnel for the down-line towards Bada Chauraha.

TBM Nana, working on the up-line tunnel, had arrived at Naveen Market Station in mid-June 2023. It should be commissioned this week, if not already, towards Bada Chauraha.
