UTTAR PRADESH, INDIA (Metro Rail News): Kanpur Metro today entered into a new phase with the lowering of the first diaphragm wall ‘cage’ at the proposed Naveen Market underground station and commencement of the casting work of the pre-cast structures for the underground tunnels in the newly built casting yard for UG section-1 at HBTU premises. Today, Shri. Kumar Keshav, Managing Director, UPMRC inaugurated the marked 04 km stretch between Chunniganj to Nayaganj under Corridor-1 (IIT to Naubasta). Four UG metro stations are to be constructed under this section. Senior officials of Uttar Pradesh Metro and Contractors Gulemak- Sam India were also present during the occasion.
The first diaphragm wall of the proposed Naveen Market metro station was lowered to a depth of about 22 meters by means of advanced cranes. The diaphragm wall can be understood as the boundary of a metro station. Before the construction of the underground metro station, this wall is constructed as a security enclosure around it. The D-wall is made up of small rectangular panels measuring around 5 meters in length and around 800 millimetres (mm) in width. Approx 100 such panels are used to prepare the D-wall of a UG metro station, 105 panels will be used in the construction of the Naveen Market Metro station.
For underground section-I, a special casting yard has been set up at the HBTU premises, where rings will be cast for the underground tunnel. Today, Shri. Kumar Keshav, Managing Director, UPMRC also inaugurated the casting process of the first ring through the machine. This ring will be made up of 6 small segments, having a total diameter of about 6 meters. The ring cast in this yard will support the tunnel during tunnelling work by Tunnel Boring Machine (TBM).
Expressing happiness and satisfaction on this occasion, Shri. Kumar Keshav, Managing Director, UPMRC said, “Kanpur Metro is moving towards a new chapter with the commencement of the construction work at the Naveen Market. It is my firm belief that our team will be able to work with the same pace and dedication which they showed during the construction of the ‘Priority Corridor’ and will be able to execute construction work of this section in the defined time frame. A new casting yard has also been set up for underground section-I at the HBTU premises, which is equipped with the state-of-the-art machines and facilities.” He also briefed about the upcoming tunnelling work, which will be executed in the near future, through the Tunnel Boring Machine (TBM).
