Average speed of the pylon’s concreting reached 2.12 meters per day
Specialists of Bamtonnelstroy-Most Group of Companies have started to build the pylon of the cable-stayed bridge across the Oka River on the M-12 Moscow – Nizhny Novgorod – Kazan Highway by continuous concreting method (applying a slip formwork).
“For the first time in the history of the Russian bridge building industry, we are erecting the 89.9-meter-high pylon of the bridge across the Oka River on M-12 Highway by the slipforming method. Before that, only foreign companies used this technology to build bridge pylons in Russia,” Deputy Chief Engineer of the Project of SK MOST JSC (part of the Bamtonnelstroy–Most Group of Companies) Vladimir Torubarov said.
This method implies continuity of concreting. It allows to reduce the construction time of the pylon by 2.5-3 times if compared to conventional methods. The average speed of continuously moving formwork reaches 2.12 meters per day.
Earlier, the specialists of Bamtonnelstroy-Most Group of Companies erected four intermediate piers of the other bridge across the Sura River on M-12 Highway on the border of the Nizhny Novgorod Region and the Chuvash Republic.
The bridge across the Oka River is the only cable-stayed bridge on the M-12 Moscow – Nizhny Novgorod – Kazan Highway under construction. It will connect the Vladimir Region and Nizhny Novgorod Region near the city of Murom. The bridge will be 1,377.6 meters long. 1,100 people and over 100 units of equipment are currently engaged in the construction.
