Gujrat ( Metro Rail News): National High-Speed Rail Corporation Limited successfully launched another steel bridge for the Mumbai- Ahmedabad Bullet Train Project on October 22, 2024. The 60-meter-long steel bridge was launched on the Bajva-Chhayapuri chord line of the Western Railway in Vadodara, Gujarat.
Steel bridge (Bullet Train Project)
This 12.5-meter-tall, 14.7-meter-wide steel bridge, weighing 645 MT, was constructed in a workshop in Bhachau, Gujarat, and then delivered to the installation location.
About 25659 Tor-Shear Type High Strength (TTHS) bolts with C5 system coating and elastomeric bearings were used in the bridge assembly; these bolts are all intended to survive for 100 years. The temporary structure was used to erect the steel bridge at a height of 23.5 meters above the ground. Two semi-automatic jacks with a 250-ton capacity each were used to pull the bridge utilising mac-alloy bars. This location’s piers are 21 meters high.
Promoting “Make In India”
While upholding the highest standards of safety and engineering quality, the project is being carried out with great care. India is progressively using its own technological and material resources to develop infrastructure under the “Make in India” initiative, using Japanese expertise. The Bullet Train Project’s steel bridge is a prime illustration of the project.
Out of the 28 steel bridges intended for the MAHSR corridor, this is the fifth to be finished.
