TERRATEC EPBMs Ready for Kanpur Metro’s 1st Underground Section in India

Gulermak/Sam India JV gets ready to commence tunneling on the Corridor-1 of Kanpur MRTS Project in India.

TERRATEC celebrated the successful site acceptance testing of two 6.52-m diameter Earth Pressure Balance Tunnel Boring Machines (EPBMs) for Uttar Pradesh Metro Rail Corporation (UPMRC) for the Corridor-1 of Kanpur MRTS Project (KNPCC-05) in India.

The two 6.52-m diameter EPBMs have started excavating for the first underground tunneling package (KNPCC-05) of the 32.4 km Kanpur Metro Phase 1 project’s 8.6-km underground section by contractor Gulermak-Sam India JV.

Kanpur Metro has two corridors: IIT Kanpur to Naubasta Corridor and Agriculture University to Barra-8 Corridor. The TBMs for the package of the 23.8 km Orange Line-1 connecting IIT Kanpur to Naubasta has a length of 3619 m and includes four stations. This includes an elevated section of 15.16 km and an underground stretch of 8.62 km.

Awarded to Gulermak-Sam India JV in Sept 2020, the contract also includes the construction of the four new underground stations at Chunniganj, Naveen Market, Bada Chauraha and Nayaganj each 215 m long.

For the geology consisting of soil, clay, silt and sandy silt, the JV selected two 6.52-m OD EPB Tunnel Boring Machines equipped with a Spoke-Type Type CutterHead with 57% opening ratios, which had been proven to be very efficient excavating this type of soil.

The two EPBMs have been launched for the initial drives from Bada Chauraha station to Naya Ganj station. Expected challenges are typical for tunneling in a densely populated, yet historical urban area.

Machine operation is assisted at all times by TERRATEC’s highly-experienced Field Service staff, providing quality after-sales support to ensure optimum performance and successful project completion. Tunneling operation is carefully observed throughout the maneuver via a settlement monitoring program.

Kanpur Metro is an urban mass rapid transit system (MRTS) being developed to meet the long-term traffic demand of the city of Kanpur in Uttar Pradesh, India. Anticipated to be completed in 2024, the 32-km long metro rail system will reduce traffics and pollution, shorten journey times and open up new career and educational opportunities in Kanpur, Uttar Pradesh’s industrial capital.

The new metro will contribute to making Kanpur safer and more business-friendly. The project will benefit climate change mitigation, by promoting a change from road to rail while reducing gas emissions, and expediting social and economic infrastructure & urban development.
