The National High-Speed Rail Corporation Limited (NHSRCL) on Friday confirmed the successful launch of India’s heaviest concrete girder for the ambitious Mumbai-Ahmedabad bullet train project. Installed at Sakhare village in Dahanu, the 40-meter full-span box girder weighs a massive 970 metric tonnes. Cast as a monolithic structure without any construction joints, it marks a major achievement in Indian infrastructure development.
Massive Concrete, Steel Used in Single Unit
The girder was constructed using 390 cubic meters of concrete and 42 metric tonnes of steel, demonstrating advanced engineering capability. Designed as a single unit, it eliminates the need for construction joints, enhancing structural integrity. According to NHSRCL, such full-span girders accelerate construction by nearly 10 times compared to traditional segmental methods, making them ideal for large-scale projects like the bullet train corridor.
Indigenous Machinery Powers Faster Progress
To facilitate such large-scale construction, NHSRCL is utilizing state-of-the-art indigenous machinery. These include straddle carriers, bridge launching gantries, and girder transporters specifically designed to handle and install such massive components efficiently. This approach supports rapid and safe construction while highlighting India’s growing self-reliance in infrastructure technology for high-speed rail development.
