METHOD FOR CONSTRUCTING METRO STATION FROM PREFABRICATED ELEMENTS USING CLOSED METHOD OF PERFORMING WORK ON EXISTING METRO LINE WITHOUT INTERRUPTING TRAIN TRAFFIC Russian patent published in 2024 - IPC E02D29/00 

FIELD: underground construction.

SUBSTANCE: used in the construction of metro running stations between operating stations on an existing metro line without interrupting train traffic. A method for constructing a metro station from prefabricated elements using a closed method for carrying out work on an existing metro line without interrupting train traffic includes the construction of a middle station tunnel between two operating running tunnels, connecting the middle station tunnel, constructed from prefabricated elements, with running tunnels without interrupting train traffic, and forming a station deep metro. In the middle station tunnel, a passenger platform is constructed with technical premises located underneath it, between the middle station tunnel and the running tunnels, openings are constructed for the passage of passengers, and the running tunnels within the metro station are converted into side station tunnels. The middle station tunnel is made of two runs with a lining of prefabricated elements; between the middle station tunnel and the side tunnels, galleries are formed within the station along the existing running tunnels, having a monolithic reinforced concrete arch and a tray slab. In the side station tunnels, on the side of the galleries, monolithic reinforced concrete walls are constructed, while the upper arches and tray slabs of the gallery lining are supported by supporting shaped blocks located at the ends of the column-run complexes and installed during the installation of the lining of the middle station tunnel, and the reinforced concrete walls of the side tunnels. Between the galleries and the side station tunnels, openings for the passage of passengers are constructed, made in the monolithic reinforced concrete walls of the side tunnels, in which sliding doors are installed on the side of the side tunnels, and the construction of a two-run middle station tunnel, galleries and column-run complexes forms a deep column metro station.

EFFECT: ensuring the possibility of constructing a column station on an operated section of the metro line, reducing the volume and timing of construction work, minimal dismantling of existing building structures, and reducing the consumption of finishing materials during the construction of a metro station.
