New Delhi [India], February 6 (ANI) : National High Speed Rail Corporation Limited has efficiently launched a metal bridge over 4 railway tracks – two of western railways and two DFC tracks between Kim and Sayan for Mumbai-Ahmedabad Bullet Train challenge.
The bridge contains of two spans – 100 m, 60 m – and can facilitate double line Standard Gauge rail observe.
This essential infrastructure improvement concerned the crossing of 4 main tracks- two western railways and two DFC tracks and an irrigation canal, a launch mentioned.
The 100 m span was launched over the western railwaysDFC tracks from January 28, 2025 to February 5, 2025 whereas the 60m span might be erected over the irrigation canal situated adjoining to the tracks on the development website.
For launching of 100 meter lengthy metal bridge (weighing 1432 metric tonnes) over Western Railway and DFCCIL tracks, 84 meter lengthy launching nostril weighing about 525 metric tonnes is used.
“This 14.3 m wide, 100 m span steel bridge having 1432 MT weight has been fabricated at a RDSO approved workshop located at Bhuj, Gujarat and transported to the site by road for installation. The 100 m span of this steel bridge was assembled at the Ahmedabad end approach of site at a height of 14.5 m from the ground on temporary structure and was pulled with automatic mechanism of 2 no. of semi-automatic jacks, each of capacity of 250 ton using 50 mm diameter Mac-Loy bars. The height of the piers at this location is 12 m,” the discharge mentioned.
The bridge meeting of 100m span utilized roughly 60000 Nos.(100 m) of Tor-Shear Type High Strength (TTHS) bolts designed for a 100-year lifespan. The 2 spans of the bridge are painted with C5 system portray and might be rested over elastomeric bearings.
The launching was accomplished with intermittent site visitors blocks on each Western Railway and DFC tracks. These site visitors blocks have been important to make sure the security and precision of the bridge launch, which was carried out in phases to attenuate disruption to common practice and freight companies.
The challenge is being executed meticulously, sustaining the utmost requirements of security and engineering excellence. Leveraging Japanese experience, India is more and more using its personal technical and materials sources to construct infrastructure underneath the “Make in India” initiative. The metal bridges for the Bullet Train Project are a significant instance of this effort.
This is the sixth metal bridge launched out of the 17 metal bridges deliberate in Gujarat portion of the alignment. Five metal bridges spanning 70 meters, 100 meters, 230 meters (100 130 m), 100 meters and 60 meters are already accomplished in Surat, Anand, Vadodara (Mumbai Expressway), Silvassa (DadraNagar Haveli) and Vadodara respectively, the discharge mentioned.
