UPMRC
Under the First Corridor (between IIT-Kanpur and Naubasta) of the Kanpur Metro Rail Project, the first Tunnel Boring Machine (TBM) segment was recently lowered in the launching shaft constructed at Bada Chauraha.

The UPMRC is speeding up the construction of the tunnel work and the process of lowering of TBM has commenced with the lowering of middle shield weighing 120 tons with the help of 400-ton and 250-ton heavy crawler cranes. This shield was placed on the cradle inside the shaft and after this Front shield, the Tail shield and the Cutter head of the machine will also be lowered inside the rectangular shaft. All these segments will then be aligned in the shaft and mechanical components and wires will be connected to complete the machine. The casting of precast concrete rings for the tunnel is going on since October 2021.

Two TBM machines will be launched from the launching shaft at Bada Chauraha, which will construct the tunnels in the direction of Nayaganj. Extensive instrumentation will be done throughout the underground stretch and continuous online and real-time monitoring is being carried out by a team of dedicated experts to ensure safety during TBM operations. The state of the art on board computerized tunnel guidance system is being provided in TBMs to ensure that the tunnelling is done as per the designed alignment to the highest level of accuracy. The TBM shall be retrieved at Phoolbagh-Nayaganj station after building a tunnel of 990m.
