Tuesday, December 13th, 2011

The builders of the bridge over the Eastern Bosphorus Strait have completed erection of a 320-meter long section of the prestressed reinforced concrete stiffening girder on the Nazimov Peninsula side. They proceeded with the concreting of the closing section of the bridge anchor pad span ion the Russky Island as well.

The span structure that has a complex and large cross-section between M1-M5 and M7-M12 bridge pillars is constructed of prestressed reinforced concrete. The amount of reinforcement of the stiffening girder on each side of the strait is about 4,000 metric tons with the concreting volume in excess of 10,500 cubic meters. The major work on the mainland side has been completed; the bridge builders have finished with the tensioning of high-tensile reinforcing strands and injected the ducts by filling them up with a special cement mortar under pressure. They have also started the concreting of the closing section in the side span where over 400 cubic meters of high-grade concrete mix out of 1,500 cubic meters as per design have already been lifted to the 70-meter elevation.
