Metro trains will run here. Breakthrough is expected in the second tunnel until July 2025. This tunnel was built at about 18 meters depths and 566 before -peric concrete rings were used. They are prepared for the modern casting yard in Mundka. The tunnel is built at a depth of about 18 meters. (Photo News18) How to get safe and durable? Earth pressure -balanced method (EPBM) technique was adopted in excavation. This technique is considered for accuracy and safety. DMRC monitored the sensors on the movement of nearby buildings throughout the tunling. The result was that neither the land nor any loss occurred in the entire campaign. Hard work Minister Dr Pankaj Singh said it was not only the victory of engineering, but the result of the center partnership and the government of Delhi. Major infrastructure projects in Delhi gained momentum in Delhi under the vision of Prime Minister Narendra Modi and Chief Minister Relha Gupta.
