India’s Longest Road Tunnel to Open in 2016
India’s longest road tunnel, being built on Jammu-Srinagar National Highway, is scheduled to be opened for general traffic in 2016 and would reduce the distance between the two cities by 31 kilometers and shorten the travel time by two hours.
The 9.2 km tunnel is part of 286 km-long four-lane project of the Jammu-Srinagar national highway. Once this tunnel becomes operational it will reduce the traffic jams on National Highway-1A that occur due to snowfall and avalanche in winter at Patnitop, Road Transport and Highways Ministry said in a release.
The tunnel, connecting Chenani in Udhampur with Nashri in Ramban district, is being completed at a cost of over Rs 2519 crore. It’s one of the marvels of technology in the field of construction.
To ensure the traffic capacity smooth, the contractors should reinforce and advance support the tunnel when digging it. Self drilling anchor system is a common system used in the tunneling industry. The application of self drilling anchor in tunneling can improve the stability and load bearing characteristics of rock mass. Under the circumstance of weak and broken rocks, large-diameter pipe shed method is an ideal tool for supporting to prevent tunnel collapse, rock deformation, and ensure construction quality and the safety of workers.
