FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in construction of underground stations erected by closed method of works. Three-vault metro station of closed method for production of pylon-type works includes three non-overlapping tunnels of round section, medium tunnel of large diameter and two smaller lateral tunnels connected to mid tunnel by monolithic reinforced concrete walkways with openings for passengers passing to train cars, as well as passenger platforms and structures of two tracks. Rail tracks are located in middle tunnel made in the form of double-line ferry tunnel without finishing of tunnel inner surface. Passenger platforms are located in side tunnels, at that, step of openings axes for passage of passengers to cars of train is equal to distance between axes of doors of cars, and openings are equipped with framing frames and sliding doors on side of middle tunnel, which open synchronously with doors of cars.
EFFECT: technical result consists in improvement of technological effectiveness and speed of construction of three-vault metro stations, as well as improved safety of metro stations operation.
