FIELD: construction.
SUBSTANCE: used in the construction of subway stations, erected by a closed method of work performance. The three-arch subway station of the closed column type contains a middle and two side station tunnels, in the side tunnels there are rail track structures, boarding platforms and technical areas under them, in the middle station tunnel there is a passenger platform with service rooms located under it, while the upper vault and the tray plate of the middle tunnel rest on walls with openings for the passage of passengers located between the middle tunnel and the side tunnels. The lining of the side tunnels has the same cross section of a closed horseshoe shape and is made of monolithic reinforced concrete. The lining of the middle tunnel is open from the side of the side tunnels, the upper vault and the tray plate of the middle tunnel rest on the walls of the side tunnels, made with openings for the passage of passengers, while the span and radius of the vault of the middle hall are the same as the side tunnels. Passenger boarding platforms are located in the side tunnels, communicating through the openings for the passage of passengers with the passenger platform of the middle station tunnel, and the openings for the passage of passengers between the platforms in the tunnels are framed in the form of additional reinforcement in the concrete body of the walls of the lining of the side tunnels.
EFFECT: improving the manufacturability and mechanization of excavation works during the excavation of station tunnels, providing a rational contour of the lining during the construction of three-arch subway stations of deep column type, as well as reducing possible sedimentation of the day surface.
