300 Km Of Viaducts Accomplished For Mumbai-Ahmedabad Bullet Practice Challenge | Mobility Information
New Delhi: India’s first Bullet Practice hall between Mumbai and Ahmedabad has reached a major building milestone with the profitable completion of 300 km of viaducts. This achievement was marked by the launching of a 40 m lengthy full-span field girder close to Surat, Gujarat, in response to the Nationwide Excessive Velocity Rail Company Restricted (NHSRCL) assertion.
NHSRCL mentioned, “Out of 300 km of superstructure, 257.4 km is constructed by Full Span Launching Technique (FSLM) together with 14 river bridges, 37.8 km by Span by Span (SBS), 0.9 km metal bridges (10 spans starting from 60 to 130 m in 7 bridges), 1.2 km PSC bridges (20 spans starting from 40 to 80 m in 5 bridges) and a couple of.7 km in station constructing.”
For developing 257.4 km of viaduct by FSLM and 37.8 km of viaduct by SBS, 6455 & 925 spans of 40 m every, respectively, had been used.
The challenge has supported using indigenously designed and manufactured tools comparable to Straddle Carriers, Launching Gantries, Bridge Gantries, and Girder Transporters for building. This marks a primary for Indian infrastructure, showcasing India’s rising capabilities in high-speed rail know-how with the assist of the Japanese authorities.
The adoption of the Full Span Launching Technique has considerably accelerated building, as full-span girder erection is as much as ten (10) occasions sooner than typical segmental strategies. Every full-span field girder weighs 970 metric tons. Segmental girders are used selectively in places the place full-span set up just isn’t possible.
To facilitate building, 27 devoted casting yards had been established alongside the hall. Metal bridges are fabricated in seven workshops unfold all throughout the nation, three in Gujarat, one every in Uttar Pradesh, Tamil Nadu, Maharashtra and West Bengal actually exemplifying the spirit of unity of our nation.
Greater than 3 lakh noise boundaries have been put in alongside the viaducts to mitigate noise throughout operations.
Along with the viaducts, the challenge has additionally accomplished 383 km of pier work, 401 km of basis work and 326 km of girder casting.
The thematic Bullet Practice stations are quickly taking form. These stations will probably be built-in with the rail and street based mostly transport system to offer seamless journey to passengers. The stations will probably be outfitted with state-of-the-art passenger facilities.
Monitor works over viaducts have additionally began, and round 157 monitor km of RC monitor mattress building has been achieved to this point in Gujarat.
The rolling inventory depots with trendy infrastructure are additionally preparing in Maharashtra and Gujarat.
This milestone is an illustration of the challenge’s sturdy planning, cutting-edge engineering, and dedication to the “Make in India” coverage.
