Rohtang Move, now known as Atal Tunnel, is a extremely popular and well-known mountain move, almost thirteen,058 ft, located on the jap Pir Panjal Selection of the Himalayas close to 51 km from Manali. Specifically acknowledged for its mesmerizing landscape, the move connects the Kullu Valley with the Lahaul and Spiti Valleys of Himachal Pradesh, India.
Recognized for its scenic elegance, Rohtang Move holds strategic significance for India. Every yr, during July to September, the highway gets to be a passage to the folks of Lahul valley transporting their funds crop, potatoes and peas to the markets across Atal Tunnel to Kullu and earning money for the unstable weather conditions time period of nine months.
The design of the tunnel was quite much awaited and was last but not least inaugurated on Oct third 2020 by India´s Key Minister Narendra Modi.
Now that we have released the Rohtang Atal Tunnel, let us see Encardio-rite’s task overview, the instrument used, and the companies supplied.
Recognized as one of the maximum trafficable passes in the entire world, the Rohtang move is developed to create an all-climate route to Leh and Lahaul and Spiti valleys in Himachal Pradesh. The Rohtang Move Highway Tunnel is situated in the Western Himalaya region of Northern India with its altitude of 3,980 m. With a duration of 9.02km, it is also the longest tunnel in the world at an altitude of in excess of 3,000 metres or 10,000 toes previously mentioned imply sea level.
For about 4 months, the pass is covered with white sheets of heaviest snowfall and blizzards, generating the route inaccessible for anybody.
Renamed after Atal tunnel from Manali to Ladakh of India, Mr. Atal Bihari Vajpayee, the tunnel lowers the travel length from 4 to 6 hrs to only 30 minutes. It also minimizes the length amongst Manali and Keylong by about forty six km (28.six mi).
The Rohtang Atal Freeway Tunnel with its 8.8km of length is the longest highway tunnel in India located at a substantial altitude. Apart from high altitude and uncooperative local weather, the geological situation in the Himalaya was a large problem faced by the Encardio Group. Braving the freezing temperature, snowfall, repeated floods and thin air, the staff soldiered forward, delivering with the most accurate sensors and instrumentations.
The rocks discovered within the tunnel spot are largely schist and migmatite with expected disturbed zones and in some person locations, large squeezing rock was also located.
Rohtang Go Tunnel Details:
Shape (cross-section) of the tunnel: Horseshoe
Completed width: ten.00 m (32.eight ft) at highway stage.
Design strategy: Drill & Blast with NATM.
Overburden: Highest 1,900 m, typical more than 600 m.
Crisis tunnel: A 2.25 m higher and 3.six m wide crisis tunnel is built-in into the tunnel cross-area beneath the major carriageway. There are eighteen egress tunnels, with an opening right after each five hundred metres in case of any hazard or emergency.
Other basic safety steps consist of telephone connections at each 150 metres for crisis conversation, fire hydrant mechanisms at every single 60 metres, auto incident detection technique with CCTV cameras at every 250 metres, air high quality monitoring at each one Km, evacuation lights/exit signs and broadcasting method throughout the tunnel between other people.
