Afcons kicks off a tunnel boring device without a diaphragm wall

Afcons has started work on the Underground (UG-1) Project of the Ahmedabad Metro's Tunnel Boring Machine (TBM) without Diaphragm Wall (D-wall).

Such a methodology has never before been applied to a metro project in India. The Istanbul Metro was built using this technique in the past.

In the UG-1 project of the Ahmedabad Metro, Afcons is building two underground stations, twin tunnels measuring a combined length of nearly 3.5 km, a cut and cover segment, as well as a ramp connecting elevated and underground parts.

The headwall construction came to a halt when the land for Kankaria Station was not handed over in a timely manner, among other reasons, and the first TBM, which was prepared for commissioning, could not be started.

Smart Roads, Smarter India

India’s infrastructure boom is not only about laying more kilometres of highways – it’s about building them smarter, safer and more sustainably.
