Dismantling of the bridge across the Oka River with a total length of 620 and a total volume of monolithic reinforced concrete – 9000 m3 using diamond technologies.
The work was carried out in stages:
The bridge structures were cut with diamond equipment into segments with a weight corresponding to the lifting mechanisms used. The segments of the bridge deck were removed by a wheeled crane with a capacity of 25 tons; a wheeled crane with a capacity of 50 tons and a crawler crane with a capacity of 180 tons were used to remove the span beams and frame consoles. Tower cranes with a capacity of 80 tons and barges. To prevent the ingress of debris into the water, garbage trapping and drainage trays and scaffolds were used. All 9000 m3 have been recycled for later use.
