Earlier this month, Afcons Infrastructure completed soil excavation work for a Tunnel Boring Machine (TBM) launch shaft in Ahmedabad’s Apparel Park neighborhood. Construction work for its diaphragm wall began in July 2017 and soil excavation work commenced towards the end of November.
This 12m deep launch shaft on the western end of Line-1’s East Ramp will in the coming months become the launch-site from where two TBMs (S710 and a new Herrenknecht machine) will be deployed for constructing 4 tunnels between East Ramp – Kankaria East Station – Kalupur Railway Station on the 6.83 km underground section of Ahmedabad Metro’s 20.737 km Line-1.
Here are some old site images shot in the middle of January when work was nearing completion. The first two images show concrete works have commenced for the base-slab in the portions where excavation is over.
Recent images will be added here when available.
