SINGLE-ARCH UNDERGROUND STATION CONSTRUCTED USING TUNNELING WITH SIDE PASSENGER PLATFORMS Russian patent published in 2023 - IPC E21D9/00 

FIELD: construction of tunnels.

SUBSTANCE: invention is related in particular to construction of single-arch underground stations using the tunnelling method of work. Single-arch tunnelled metro station with side passenger platforms contains lining of the station with an upper arch resting on monolithic concrete supports and formed from arches, each of which consists of reinforced concrete blocks, while in the upper part the arches contain lock blocks installed with Freyssinet flat jacks. Inside the station lining there are rail track structures made in form of double-track tracks in the central part of the station, and technical rooms are located under the side passenger platforms. The station is equipped with passages to the side passenger platforms on monolithic concrete supports constructed in the support tunnels, a reverse arch of the lining made of monolithic reinforced concrete and resting on concrete supports, reinforced concrete structures for maintenance and technical premises above the passenger area along the entire width of the station. Two blocks with additional Freyssinet jacks are installed in the arches of the upper arch, one on each side, symmetrically relative to the axis of the station's upper arch, and the station's rail track structures are connected to the double-track running tunnels of the metro line.

EFFECT: increase in the spatial rigidity of the station lining, less time spent, reduction of internal volumes of the station, deformability of the station arch and the magnitude of possible soil settlement over the station, as well as the possibility of using the design of the station on metro lines with double-track running tunnels.
