FIELD: construction of tunnels.
SUBSTANCE: invention relates to the field of tunnel construction, in particular, to construction of single-vault metro stations built by a closed method for work performance, primarily deep-laid. A single-vault metro station with cast reinforced concrete lining, built by a closed method for work performance, having a box shape in the cross-section and consisting of an upper vault, a reverse vault, and walls, located wherein are rail track structures and an island passenger platform with maintenance and technical rooms located under said platform. The lining of the station consists of two layers, wherein each layer is made of cast reinforced concrete. The first layer of the lining is constructed in accordance with the technology of sprayed concrete with anchors, and the second layer is constructed using formwork, a waterproofing layer is placed between the layers of the lining. The lining has a raised upper vault allowing for placement of maintenance and technical rooms above the passenger platform and the rail tracks.
EFFECT: ensured rational contour of the lining, increased speed and manufacturability of construction, and improved safety of construction and reliability of operation of the metro station.
