GLM-SAM Begins Kanpur Metro Chunniganj Station’s D-Wall Work

Gulermak – Sam India Builtwell JV on Saturday began work to construct the diaphragm wall (D-wall) of Kanpur Metro’s Chunniganj Station on Package KNPCC-05.

This station on the 32.385 km Phase 1 project’s first underground section (Permat Ramp – Nayaganj) is the last of 4 stations where grabbing and trenching activity has finally started due to land acquisition issues.

3.964 km Package KNPCC-05’s construction contract was awarded to Gulermak – Sam India in March 2021 with a combined value of Rs. 769.23 crore & USD 3.674 million.

Their scope includes building twin tunnels from a ramp at Permat (east of Motijheel Station) to Nayaganj via four stations at Chunniganj, Naveen Market, Bada Chauraha and Nayaganj – each 215 meters long.

Some snaps from Chunniganj Station’s site in front of BNSD Inter College via UPMRC:

UPMRC expects similar work at Naveen Market Station and Bada Chauraha Station to be over in April. Per them, 87 / 102 D-wall panels have been installed at Naveen Market, 84/100 panels at Bada Chauraha and 68/107 at Nayaganj Station.

Here’s my go-to video to demonstrate how D-walls are built to form the boundary wall of station boxes:

Gulermak-Sam plans to deploy 2 Terratec Earth Pressure Balance (EPB) machines, S92 and S93, in the coming months from Bada Chauraha Station – see snaps and tunneling plan here.
