With last girder launch, DMRC completes work on G Noida line
New Delhi: The last girder was launched by the DMRC to mark the completion of the viaduct on Noida - Greater Noida Corridor, on Tuesday. Moreover, with the erection of this girder, the viaduct of approx 30 kilometers has been completed.
According to the DMRC statement, the civil work on this corridor was began in may 2015 and the first girder was erected in December 2015 and nearly, within a span of 22 months, the corporation has erected a total of 2830 girders. This last U- girder was launched between Sector 143 and Sector 144 stations of the corridor.
The statement further reads that DMRC had successfully executed the task of erecting 200 U-girder on the Noida–Greater Noida corridor in the month of May 2016. This is the maximum number of U-girders ever launched in any Metro corridor in India within a month. "DMRC used six special trailers to transport the girders and six special cranes of around 350/400 tonnes capacity to launch the 27 meters long and 5.05 meters wide U-Girders," said an official.
"DMRC had also entered the prestigious Limca Book of Records for this feat and Dr. Mangu Singh was formally handed over the Certificate from the Limca Book of Records on 2nd March 2017," he added.
The 30 Kilometers entire corridor Noida- Greater Noida, completely elevated and having 21 metro stations, on standard gauge which also cross Yamuna-Agra flyover at 21 meters. "All the stations on this corridor will have platform screen doors, water harvesting facility and solar panels,' the statement reads. Meanwhile, the first set of trains has left China and is expected to arrive at the Greater Noida Depot by mid-December.
"The viaduct on the Noida – Greater Noida corridor was constructed by specialised technique of pre-cast pier caps and precast U-girders. However, the main challenge of girders is precision in casting as well as launching which required specialised cranes of 350/400 tons capacity to launch these girders," it is said in statement.
The statement further said that all the girders were pre fabricated at the two Casting Yards located in Noida Sector 149 and Depot Station in Greater Noida, and each weighed approx 153 tonnes.
