RRTS Corridor Crosses Partapur Rail Line With Installation Of Two 45-Metre-Long Special Steel Spans
RRTS corridor over Partapur rail line
RRTS corridor has finally crossed Partapur Railway line successfully with the installation of two 45-metre-long special steel spans. The installation process unfolded in multiple stages, involving the construction of two portal pillars (U shell beams) and the subsequent installation of two steel spans over them.
In order to provide the RRTS services to the city residents, it was mandatory to cross the railway line at Partapur. A flyover already exists for traffic on the roadway.
The RRTS corridor was also required to cross the railway line to go in the direction of Meerut. To make it possible, these two special steel spans have been installed with the help of high-capacity cranes.
NCRTC has temporarily taken the block of the railway route for a minimum period for this installation as per the pre-decided plan. Two tracks will be built on these steel spans for the arrival and departure of trains.
The length and weight of these two steel spans are approximately 45 metres and 350 tonnes each. These steel spans are special in the way that they are constructed with the help of composite steel. Once the RRTS corridor is built, Namo Bharat trains will cross the railway line at a height of about 19 metres.
Moving from Delhi towards Meerut, Meerut South Station is the first station in Meerut. Partapur is the second and the next station. These newly installed special steel spans will connect these two stations.
Installation of the steel span on the railway line at Partapur was a challenging task, but Team NCRTC, following all the norms and precautions, successfully installed both steel spans. During this whole process, NCRTC received full cooperation from the concerned railway departments.
For the construction of an elevated viaduct of the RRTS corridor, NCRTC usually erects pillars at an average distance of 34 metres. These pillars are joined by pre-cast segments with the help of a launching gantry (tarini) to form the RRTS viaduct span.
However, in some complex areas where the corridor crosses rivers, bridges, rail crossings, metro corridors, expressways or other such existing structures, it is not practically possible to maintain this distance between pillars. Special steel spans are being used to connect the pillars in such areas.
NCRTC aims to make the entire 82 km long Delhi-Ghaziabad-Meerut corridor operational for the public by June 2025.
