The construction of the approximately 5 km long Baradevi-Naubasta elevated section of Corridor-1 in the Kanpur Metro Rail Project is progressing rapidly, with the erection of steel spans over the Naubasta flyover starting on Saturday. This significant development marks a crucial phase in the Kanpur Metro’s expansion, aiming to enhance the city’s public transportation infrastructure.
The first segments of the steel box girders, each about 30 metres long, were erected approximately 6 metres above the flyover using specially constructed temporary structures on both sides. These steel box girders are a pivotal component of the elevated section, designed to provide robust support for the metro tracks. The temporary structures used for the erection ensure the safety and precision required for such a complex engineering task.
In the Kanpur Metro infrastructure, U-girders and I-girders are essential components for constructing viaducts that support the metro tracks. U-girders, with an average length of 27 metres, have been commonly used in various sections of the Kanpur Metro. These girders are known for their efficiency in supporting the weight and stress of the metro trains, ensuring a stable and secure track foundation.
For this particular span over the Naubasta flyover, the decision was made to utilise 45-metre-long steel box girders. These girders are being erected in three segments each for both the “up-line” and “down line.” The choice of longer girders is strategic, aimed at enhancing the structural integrity and continuity of the elevated section. On Saturday morning, the first segments of girders for both lines, each approximately 30 metres in length, were successfully erected. This milestone marks a significant step forward in the project, demonstrating the efficiency and expertise of the construction team.
With the addition of two more segments, the length of both steel box girders will reach 45 metres each, facilitating the seamless continuation of the project. The precision in the alignment and connection of these segments is critical, ensuring that the entire structure can support the metro trains’ dynamic loads and vibrations.
The Baradevi-Naubasta elevated section is a crucial part of the Kanpur Metro Rail Project, designed to improve connectivity and reduce travel time for commuters in the city. This project is expected to significantly alleviate traffic congestion, providing a reliable and efficient public transportation option for the residents of Kanpur. The integration of advanced construction techniques and materials underscores the commitment to building a state-of-the-art metro system that meets international standards.
As the project progresses, the successful completion of the steel span erection over the Naubasta flyover will pave the way for subsequent construction phases, including track laying, station development, and system integration. The Kanpur Metro Rail Project is poised to transform urban mobility in the city, contributing to sustainable development and enhancing the quality of life for its citizens.
