The National Capital Region Transport Corporation (NCRTC) has successfully installed six special steel spans for the Delhi section of the Regional Rapid Transit System (RRTS). These spans, vital for the system's infrastructure, cross challenging areas like the Gazipur Drain and Kondli roundabout.
In a significant milestone for the National Capital Region Transport Corporation (NCRTC), all six special steel spans for the Delhi section of the Regional Rapid Transit System (RRTS) have been fully installed. These unique structures were put in place to traverse the Gazipur Drain and Kondli roundabout, making this segment a unique feature along the RRTS corridor.
According to an NCRTC senior official, these spans are manufactured in a factory, segmented and then moved on-site during nighttime hours to minimize traffic disruption. These giant segments are systematically assembled at the site, using a special process to ensure stability and structural integrity.
The design of these special steel spans is customized to meet specific construction, installation, and usage requirements. The components of these spans are sizable beams of structural steel, and their installation represents an engineering marvel given the challenges of the locations.
The total length of the six spans is around 360 meters. The RRTS corridor, which originates from Sarai Kale Khan, runs parallel to the Gazipur Drain and now successfully crosses it with the help of these spans. The steel spans not only provide structural support but also play a vital role in the overall functionality of the RRTS system.
Each of these steel spans has its own dimensions. Three of the spans are approximately 70 meters long, each weighing 540 metric tons, while the remaining three are around 50 meters long and weigh the same. The spans are about 14 meters wide, a feat of engineering that facilitates the smooth operation of the RRTS.
Installation challenges were numerous. The span near the Ghazipur Drain was particularly tricky due to its diagonal orientation to the RRTS alignment. Furthermore, existing structures like Public Works Department roads and Delhi Jal Board pipelines added to the complexity of the project. High-capacity cranes were deployed to handle these challenges, ensuring a sturdy foundation for the steel spans.
The successful installation of these six steel spans represents a crucial step forward for the RRTS corridor in Delhi. Despite several engineering and logistical challenges, NCRTC's achievement marks an essential phase in bolstering the city's public transit infrastructure.
