23,800 cubic meters of concrete and 3,126 tons of reinforcement cage were used to build 17 piers
Сoncreting of the last section of the pylon of the river pier No. 4 on the right bank marked completion of all 17 piers of the bridge crossing under construction across the Oka River on the M-12 Moscow – Nizhny Novgorod – Kazan Highway.
During the construction of this pylon, the continuous concreting method using a sliding formwork has been applied for the first time in the Russian bridge construction industry. In comparison to self-climbing formwork, this method allows to reduce time needed to build piers by more than two times due to the continuity of concreting. Both pylon legs were erected simultaneously at a speed of up to 2.2 meters per day. A sliding formwork was used to erect 85.1 meters of the pylon. The remaining 4.8 meters were constructed using panel formwork. The pylon is 89.9 meters high. 1,380 cubic meters of concrete and 87.6 tons of metal structures of the anchorage zone were used to build it.
The pylon of pier No. 3 on the left bank of the Oka River was erected using self-climbing formwork. The pylon is 80.6 meters high. 1,165 cubic meters of concrete and 88.1 tons of metal structures of the anchorage zone were used to erect it.
“Today, we have poured the last 18.8 cubic meters of concrete, thus actually completing the construction of the final pier of the bridge crossing across the Oka River. 23,800 cubic meters of concrete and 3,126 tons of reinforcement cage were used to construct all 17 piers,” Deputy Project Manager – Head of the Oka Branch Office of Bamtonnelstroy-Most JSC Daulet Sizo said.
The bridge across the Oka River is the only cable-stayed bridge under construction on the M-12 Moscow – Nizhny Novgorod – Kazan Highway. It will connect the banks of the Vladimir and Nizhny Novgorod regions near the city of Murom. The bridge is 1,377.6 m long and has a 254-meter-long cable-stayed central span. 1,100 people and more than 100 units of equipment are involved in its construction. Work is going on around the clock.
