Lyublinsko-Dmitrovskaya Metro Line

Moscow Metro Development Program has no world analogues, impresses with its scale that involves the maximum extent of available resources. The Group of companies Mosproekt-3 engineers were actively involved in the work from the start of an unprecedented project and maintained their leadership status in the sphere of underground space development in the shortest possible time.

Being a key participant of Moscow Metro Development Program, the Group of companies Mosproekt-3 provides it with unique technical solutions. The competence of the  engineers of the Group of companies enabled to implement the deep-laying section of the Lyublinsko–Dmitrovskaya Line in the shortest time possible, in the aqueous soil, the engineers applied special methods, including freezing method.

The construction of the northern section of the Lyublinsko–Dmitrovskaya Line was carried out in the conditions of dense residential and industrial urban development with a large number of already existing engineering systems and in close proximity to railway infrastructure. Furthermore, the engineering and geological conditions were fairly rough: composite soil was prevailing along tunnel tracks, most of it was also aqueous soil type. Tunneling was conducted with a use of Tunnel Boring Machines (TBM) and by applying drill and blast method. During the construction of the station, main line and inclined escalator tunnels located in the aqueous soil, chemical grouting and freezing method were used.
