The builders of the bridge over the Eastern Bosphorus Strait have completed the concreting of the main structure of M7 Pylon on the Russky Island. The leg of the giant support have reached the elevation of 319.9 meters above the sea level and are now practically of the design height.
After the last 71st sections have been concreted, M7 Pylon is higher than a 106-story skyscraper. Figuratively speaking, two Eiffel Towers rise now on the shores of the Eastern Bosphorus Strait after the main bridge supports on the Nazimov Peninsula and on the Russky Island have reached the 320-meter height as per design. It will take to finish one concrete pouring section to complete the pylon erection.
“The concreting of the main or “standard” sections that form the pylon body has been completed,” explains Aleksey Baranov, Director of the OJSC USK MOST Branch in Vladivostok. “The final phase of the work is to tie up the two pylon legs by means of reinforced concrete cross-pieces at the level of the 71st sections to impart stiffness to the entire structure. The legs will be then capped with concrete “lids” each about one meter thick, which will support a top pyramidal structure. This will be the closing 72nd section, whose function is to protect the pylon interior space from atmospheric factors and to impart the final architectural appearance to the major bridge support.”
The builders of the SK MOST Group of Companies have completed erection of the main structure of M7 Pylon within a world record breaking time, practically within two years. A total of 40 thousand cubic meters of high-grade concrete mix have been placed in the bodies of the giant supports on both sides of the strait.
