The pace of work in Lucknow never ceases to amaze me 😀
On Monday, the Tata – Gulermak JV began casting concrete segments for building the 1,812m long twin tunnels of the 3.44 underground section between Charbagh and KD Singh Babu Stadium at its casting yard in Sector 19, Vrinadavan Colony. Roughly 2600 segments will be cast using moulds imported from South Korea and later be fed into the two Terratec Tunnel Boring Machines to build & line the tunnels.
As per a LMRCL press release:
The average daily requirement of segments at construction stage will be 60 segments (i.e. 10 rings) as against production capacity of 72 segments (i.e. 12 rings). Sufficient reserve stock of segment will be maintained at two stacking yards located within the Casting Yard. Casting Yard has state-of-the-art installation and facilities that include Automatic Reinforcement Cutting and Bending machine, RO Plant, Automatic Batching Plants, Fully Equipped Quality Control Lab, Health Unit with round the clock ambulance facility, Safety induction and training hall etc.
I’ve shared this before but it’s a perfect time to rewatch this excellent video demonstrating how the segments will be used to build rings for Lucknow Metro’s tunnels. Skip to 5 mins and 15 seconds if doesn’t do so automatically.
As per the LMRCL, one of the 2 TBMs (view images) has been dispatched from Delhi and is expected to arrive in the city by the end of the month. The 2nd TBM will be inspected next week and will be dispatched by the end of the month.
