J & K Project Brief

Alignment Plan- USBRL Project

1. Background :

  • Project –Udhampur-Srinagar-Baramula Rail Link Project(USBRL)

  • Length – 272 Km.
With a view to provide an alternative and a reliable transportation system to Jammu & Kashmir, Govt. of India planned a 272 Km. long Railway Line from Udhampur to Baramulla joining the Kashmir valley with the Indian Railways network under Udhampur-Srinagar-Baramulla Rail link Project (USBRL). This project has been the most challenging works undertaken post-independence by Indian Railways. In view of importance of USBRL project in providing seamless and hassle-free connectivity, the Project was declared as “National Project” in 2002. The alignment of USBRL involves construction of a large number of Tunnels and Bridges in highly rugged and mountainous terrain with most difficult and complex Himalayan geology.
This Project involves 38 Tunnels (combined length of 119Km), the longest Tunnel (T-49) is having a length of 12.75 Km and is country's longest transportation tunnel. There are 927 nos. of Bridges (combined length of 13 Km). These bridges include the iconic Chenab Bridge (Overall length 1315 m, Arch span of 467 m and height of 359 m above river bed) which will be the highest railway bridge in the world. Indian railway's first cable stayed bridge is also being constructed on Anji Khad.

a) Chenab bridge on River Chenab

The iconic Chenab bridge is being constructed in Reasi district of Union territory of Jammu and Kashmir under the most challenging Udampur- Sringar- Baramulla- Rail-link project (USBRL) Project of Indian Railways. The bridge is about 111 km by Road from Jammu on ongoing Katra- Banihal section.

 

chenab
Fig1 : Key Plan of the Bridge

This iconic bridge across the river Chenab having central span of 467 m is being built at a height of 359m from the bed level (Height of QutabMinar is 72 m and of Eiffel Tower is 324 m). This is the Highest railway bridge on the globe being constructed. For construction of Arch portion of bridge over the river, a novel method of construction using the cable car is designed and commissioned. Two number of cable cars having capacity of 20 MT each and 37 MT in tandem runs on 54mm cables laid across the river valley and connected through 127 m high pylon (tower) on Kauri end & 105 m on Bakkal end of the river.
The Chenab bridge will usher in fresh era in J&K due to Increased employment opportunities for the youth, improved infrastructure due to construction of access roads, Better facilities for students to travel to other parts of the country for educational purposes, Boost to tourist industry, connectivity of far flung areas to mainstream of country and overall economic development of the state. Remotely located Villages at kauri and Bakkalends of construction sites, which until now have no vehicular means to travel to Reasi district and other places , have started enjoying fruits of development brought about by construction of black topped approach roads in region. Infact, A window of worldful of opportunities has opened up to local population of the region.

B. Status of Chenab Bridge construction:
• Earthwork in excavation completed.
• All foundations of Chenab Bridge (18 Nos) & substructure completed.
• Launching of 490m deck (superstructure) on transition & circular curve from Kauri end of Chenab Bridge has been successfully completed.
• Fabrication work in progress.
• All Fabrication works for Piers, trestles & arch completed.

b) Anji Bridge:
Construction of Anji Bridge is extremely difficult and an Engineering challenge. Although, it is smaller in comparison to Chenab Bridge, but it is also an important bridge on this section and after construction, it will be 195m above the river bed and main span across steep slope of Anji Khad River will be 290 mtrs. AnjiKhad Bridge is country's "first cable-stayed bridge" on Indian Railways.

The bridge is located in the young fold mountains of Himalayas having extremely complex, fragile and daunting geological features in the form of faults, folds and thrusts and besides seismic proneness of the region. Detailed site specific investigations were carried out by IIT, Roorkee and IIT Delhi. Slopes of the mountain supporting one foundation of main span have been stabilised by a special hybrid foundation on Katra end due to space constraints. The major portion of the bridge works including Main Pylon with 40m deep Hybrid foundation, Central Embankment and Ancillary Viaduct were carried out on Srinagar end.
For ease of construction and keeping in view the typical site conditions, this bridge has been divided into 3 parts:
• 120 m long approach viaduct (called “ancillary viaduct”) on Reasi side.
• Main bridge, crossing the deep valley (473.25m cable stayed portion).
• Central embankment (94.25m), located between the main bridge and an approach (ancillary) viaduct.

AnjiKhad Bridge connects tunnel T2 and T3 on the Katra-Banihal Section of the Udhampur-Srinagar-Baramulla Rail Link project. AnjiKhad Bridge has a single main pylon of height 193m from the top of foundation, standing at a height of 331 metres above the river bed. The total length of Bridge is 687m consisting of Main Bridge having the length of 473.25 metres, Ancillary viaduct of 120 metres length and the central embankment of 94.25 metres length. It is an asymmetrical cable-stayed bridge balanced on the axis of a central pylon. The Total deck Width of Bridge is 15m.

Various unique techniques and equipments are being used like DOKA JumpformShuttering .Pump Concreting System to increase efficiency, providing higher safety for workers and for saving construction time. State of the art Tower crane, make 'COMANSA'(imported from Spainof 40 T capacity with extentendable height up to 205 mtrs is being used for enhancing the construction activities for heights upto 193m. Status report of the bridge: The Ancillary viaduct portion has been completed. Central Embankment has been completed. Sub-Structure Completed. Main Pylon will be 193 M when completed.

c) Brige no 43: Launching of super structure of Mega Bridge no. 43 having length of 777m with span arrangement (1*35+1*53+ 10*64+1*49) is under progress

Bridge No 39: Launching of superstructure of Mega bridge no. 39 having length of 490m with span arrangement of 1x53.15 + 6 x 64 + 1x 53.15 meters is under progress
