Meerut, India (Metro Rail Today): The Delhi-Ghaziabad-Meerut RRTS corridor witnessed its fourth successful tunnel Breakthrough in Meerut today. Sudarshan 8.3 (tunnel boring machine), which is constructing this tunnel, has successfully completed the construction of about 750 meters long tunnel between Gandhibagh and Begumpul station and made a breakthrough on the tunnel retrieving shaft constructed at Begumpul station.
This is the second parallel tunnel between Gandhibagh and Begumpul, whose construction has been completed. Sudarshan 8.3 had completed the work of the first tunnel between Gandhibagh and Begumpul in the October last year. Two parallel tunnels are to be constructed for to and fro movement of trains in the RRTS corridor. After completion of this second parallel tunnel from Gandhi Bagh to Begumpul, the tunnel construction of this section is now complete.
This is the fourth successful tunnel breakthrough of the RRTS corridor in Meerut. Earlier, the underground portion between Bhainsali to Meerut Central Station have been completely constructed, where Sudarshan 8.1 and 8.2 has completed the construction of entire parallel tunnels.
After completion of construction of two underground sections (4 tunnels), Now the construction work of both the parallel tunnels of the third and last underground section of Meerut is progressing. Two parallel tunnels of 1 kilometer each are to be built between Bhainsali to Begumpul, out of which the construction of the first tunnel, Sudarshan 8.1 has started two weeks back.
For the construction of second parallel tunnel between Bhainsali to Begumpul, the process of re-assembling the Sudarshan 8.2 parts has been started.
For today's tunnel breakthrough, More than 3500 pre-cast segments have been used for the construction of this 750 meter long tunnel built between Gandhibagh to Begumpul. Casting of these tunnel segments is being done at NCRTC's casting yard at Shatabdi Nagar, with assured quality control. Pre-casting helps in safe and speedy execution of works while ensuring quality control.
After the construction of the tunnel, the work of laying track inside the tunnel will be started. Along with this, the works of OHE and signaling etc. will be done. Precast track slabs are being manufactured at the track slab factory of Casting Yard, Shatabdi Nagar, Meerut. These track slabs will be taken to the site of the tunnel through trucks-trailers and installed. This work is being done at a fast pace in line with the target of opening the entire corridor to the public by 2025.
