Yes Ananya...The biggest challenge in this construction is the alignment. @ saran.. As soon as the piers are ready, traffic problems will be reduced. This is because after completion of piers, most of the remaining work will be done on top.
Hi all...i read that these launch girders will be initially made and tested at the casting yard before it is transported to the work site. They will be further checked for maneuverability and safety at construction site. These launch girders are hinged so that during binding they can tackle the curves of the alignment.
Each girder used here weigh around 300 tonnes and has a length of 34 cm. These girders help to place segments between two piers. These piers will be lifted from the trailer on the ground and later on they will be bonded together by glue to form a viaduct on which the two way rails will be laid.
Hi Mritunjoy...L&T is planning to add four more launch girders at two different construction spots. Thus citizens will again be entangled with traffic at few road stretches. The Hyderabad metro will have total 28 hinged launch girders across three corridors in city.
