Lucknow Metro’s TBM S52 Starts Tunneling towards Hazratganj

Following a small pooja and ceremony, workers from the Tata – Gülermak JV today commissioned TBM S52 – their first Tunnel Boring Machine from the Bapu Bhawan Shaft located adjacent to the Sachivalaya (State Secretariat) Station’s site for the 3.44 km package LKCC-06 of the 22.878 km north-south line.

This Ø6.52m Terratec Earth Pressure Balance (EPB) TBM, nicknamed Gomti after the Gomti River, has started building temporary rings for the down-line tunnel within the shaft and will travel on a 780 meter journey towards the Hazratganj Station. The 1st precast segment, to form 1,812m twin tunnels, was cast at Tata-Gulermak’s yard in November 2016 and parts of this TBM were lowered into the shaft in early January 2017.

With this development, Lucknow is now the 6th city in India, after Kolkata, Delhi, Bangalore, Chennai and Jaipur, to have an underground metro tunnel.

By mid February, the Tata-Gulermak JV will also commission TBM S53, which has been nicknamed Ganga, towards Hazratganj. Both TBMs were previously deployed by the HCC-Samsung JV on the Delhi Metro’s CC-34 project (Vikaspuri – Palam section of Magenta Line) and nicknamed Jantar and Mantar. In 2014-2015, they successfully completed tunneling the Vikaspuri Shaft – Janakpuri West & Dashrathpuri – Palam sections, and were subsequently put up for sale by HCC.

      That’s correct. And Pune or Kanpur will go on to be the 9th.

        I dnt think so that Pune or Kanpur will get settled on 9th position.In Pune metro work is in very early stages,and initial project is elevated from pimpri mahanagar palika till shivajinagar, a big hurdle is there at kasarwadi where the metro project is fouling with doubledecker bridges,so it will take a handful 3-4 years fr underground work to start.Kanpur too is in very initial stages.What about Hyderabad or Nagpur?arnt there any underground section?
