The all-weather Chenani-Nashri tunnel being constructed with the cost of Rs 2519 crore on Srinagar-Jammu Highway will be completed in next three months. The tunnel besides being all-weather will reduce the distance between the two capital cities of the state by 31 kilometers.
The Chenani-Nashri Tunnel (or Patnitop Tunnel) in Udhampur, in the Indian state of Jammu and Kashmir, will be the longest road tunnel project in the country when opened for traffic in 2016. The 9km long Patnitop tunnel, being built at the foot of the Himalayan mountains, will connect the districts of Chenani and Nashri.
The Patnitop tunnel is a part of the planned four-lane widening of the National Highway 1A (NH1A) between Srinagar and Jammu. The tunnel will act as an alternative to the existing NH1A section, which faces geometris and safety concerns, as it passes through steep mountain terrains.
Rock bolting system is an effective and popular anchoring system extensively used in tunneling. When the tunnel is built in the mountain terrain or the surrounding of broken rock, loose soil layer and difficult to drill, rock bolting system can put drilling, grouting and anchor together without casing pipe and drilling pipe, and then ensure the anchoring effort in the complicated geological condition. Rock bolting system owns the features of convenience, reliability and high-efficiency.
