Chenab Rail Bridge: the Tech Behind the World’s Highest Railway Bridge

[ad_1] Chenab Rail Bridge, the best rail bridge and arch bridge on the earth, is all set to be inaugurated by Prime Minister Narendra Modi on Friday. The inauguration ceremony is for the 63 km stretch of the Katra-Sangaldan part, a part of the Udhampur-Srinagar-Baramulla Rail Hyperlink (USBRL), which additionally contains the Chenab bridge. Other than that, the PM may even inaugurate the Anji Bridge, which is India's first cable-stayed rail bridge.

After the inauguration, Modi may even flag off the primary Vande Bharat Practice to journey on the world's highest arch bridge, making it absolutely operational. The bridge, which can be being referred to as an engineering marvel, required the usage of state-of-the-art equipment and human craftsmanship. To underpin the know-how behind the challenge, now we have listed the highest 5 issues to know concerning the Chenab Rail Bridge.

Chenab Rail Bridge: An Overview The Chenab Rail Bridge is constructed over the Chenab River within the Reasi district of Jammu and Kashmir. Constructed utilizing metal and concrete, it covers a distance of 1,315m throughout the river gorge. The size of the primary arch is 467m (linear) and 550m (curvilinear). Underneath the manager company of the Konkan Railway Company, the development challenge was dealt with by Afcons Infrastructure. The bridge value Rs. 1,486 crore to assemble and has an anticipated lifespan of 120 years.

Hoisted 359m above the riverbed, the Chenab Rail Bridge supersedes the Daduhe River Railway Bridge in China because the world's highest rail bridge. As per Afcons, it's 35m taller than the Eiffel Tower. The challenge required the fabrication of 28,660 metric tonnes (MT) of metal. The construction is designed to deal with trains travelling on the velocity of 100kmph and wind speeds of 266kmph.

Tech Behind the Chenab Rail Bridge Coming to the design, the bridge makes use of a two-rib metal arch design with an open spandrel development. Open-spandrel implies that the rail deck sits on vertical helps rising from the arch as an alternative of being steady. Weathering metal was used for the development of the bridge, which is corrosion resistant and permits for temperature variation between -20 levels Celsius to 45 levels Celsius. Every phase of the bridge weighs 34 MT and was erected utilizing the assistance of the world's tallest cable crane with a 127m excessive pylon, Afcons mentioned. That's taller than the Qutub Minar. The Chenab Rail Bridge is designed to bear earthquake forces of the best depth zone-V in India. To make sure that the construction is safe, Phased Array Ultrasonic Testing machines had been used to check the welds, a primary in Indian Railways. Curiously, the bridge required roughly 5,84,000km of welding to hitch totally different elements — about the identical distance between Jammu Tawi and New Delhi. All through the bridge, structural well being monitoring (SHM) techniques have been positioned. Greater than 100 sensors have been put in that monitor wind parameters, environmental situations, structural responses comparable to vibration and cargo, and extra. These sensors consistently ship information to alert mechanisms. If any of the values are discovered to be past the security parameters, it triggers a pink sign to halt prepare operations and sounds alarms to alert station masters and management rooms. The well being monitoring of the bridge is being dealt with by Tranz Rail Options together with Strainstall, a part of the James Fisher group.
