Terratec, Afcons Infrastructure, Sam India Consortium and Uttar Pradesh Metro Rail Corporation have celebrated the final breakthrough on a 2.2km upline of India’s Agra Metro project.
In November, a Terratec 6.61m-diameter EPBM broke through on the tunnel from RBS College Ramp to Agra College Interchange Station.
Originally employed as a 7.51m-diameter EPBM for India’s first regional rapid transit system project spanning 82km to connect Delhi, Ghaziabad, and Meerut, TBM S115 has been refurbished and converted into a 6.61m-diameter machine. It has been re-engineered for the Agra project, where it has tackled challenging clayey silt, sandy silt, and silty sand conditions. It completed the 1.942km drive in less than a year.
The project uses Terratec’s 275mm-thick x 1400mm-long reinforced concrete Universal-style pre-cast lining rings, efficient muck removal via rolling stock, and three 45-tonne battery locomotives.
The Agra Metro Phase 1 project is a 14.25km Line-1 route from Sikandra to Taj East Gate. This latest breakthrough marks S115’s third completion and is the seventh breakthrough on Line-1’s underground section, outside the operational Priority Corridor, between RBS Ramp and Mankameshwar Mandir Station.
TBM S115 will later be redeployed for the Jaipur Metro project.
