In the conditions of an acute shortage of street and road network, the Chord Ring of Moscow is designed and engineered to provide Moscow with high-speed cross-links in the middle part of the metropolis. The South-Eastern Chord is going to reduce traffic load on the busiest roads and in the future will be extended to New Moscow.
Engineering solutions made by The Group of companies Mosproekt-3 engineers on the sections of the South-Eastern Chord provide the residents of Pechatniki and Biryulyovo Zapadnoye District with the new alternative routes. These districts used to have poor transport accessibility and to be divided by numerous natural and artificial barriers.
On the section from Grayvoronovskaya to Shosseynaya Street, the engineering structures cross twice The Kursky Suburban Railway Line and the Big Circle Line tunnels under construction, as well as the operating sections of the Tagansko-Krasnopresnenskaya Line. To reduce the noise and vibrational effect, we applied foundations with auger cast piles. Furthermore, the diameter of each pile was selected individually in each specific situation. For instance, in particularly cramped conditions we used piles up to 2 meters in diameter.

To optimize the construction of the South-Eastern Chord section from the Paveletsky Suburban Railway Line to Moscow Automobile Circle Road (MKAD), our specialists applied different approaches to different parts of the engineering structures. On the section, where we didn’t have to deal with the issues connected with topography or existing development, we used reinforced concrete prestressed beams for a span construction. For the spans that cover railway lines, we used metal structures and orthotropic deck. The third section has a complex geometry, that is why we chose reinforced concrete ribbed plates due to the span’s location, as it is located both at the entrance and exit roads of the South-Eastern Chord main road.
