METHOD FOR ERECTION OF THREE-VANE SUBWAY STATION OF CLOSED METHOD OF PERFOMING WORKS WITH DOUBLE-TRACK MAIN LINE TUNNEL Russian patent published in 2019 - IPC E02D29/00 

FIELD: construction; subway.

SUBSTANCE: invention relates to construction of tunnels, in particular to a method of constructing subway stations of column type of closed method of performing works. Method of constructing a three-vane subway station of a closed method of performing works with a double-track main line tunnel involves erecting a middle station tunnel from a round lined garbage collection consisting of reinforced concrete tubes, the outer diameter of which is equal to the diameter of the main line tunnel adjacent to the station, wherein tubing rings are made with rectangular section in plan and are mounted without bandaging joints between them. Lining of the middle station tunnel is constructed during tunneling of the main line tunnels by the same tunnel boring mechanized complex, at the places of passage between the tunnels temporary filling tubes are mounted, then monolith reinforced concrete reinforcement cages are concreted by one-sided increase of cross-section, before concreting of which reinforcement is installed, which is fixed to bolt fastenings of tubing lining of the middle tunnel. In reinforcement body additional reinforcement frame monolith frame frames are installed, which is attached to working reinforcement of cages and bolt fasteners of lining of middle station tunnel. After strength gain of concrete reinforcing rings of middle tunnel is constructed side station tunnels, rings of side tunnels are open from side of middle tunnel and rest on its lining. In side tunnels monolithic reinforcement chords are concreted from side of middle tunnel by one-sided increase of cross-section, for this purpose reinforcement of cages is installed, which is fixed to bolt-on fastenings of tubing lining, additional reinforcement of framing openings of monolithic frames is installed in frame body, which is fixed to working reinforcement of races and bolt fasteners of lining of side station tunnels. At the passages of the passenger passages, through openings are made, for this purpose temporary filling tubing is dismounted. Upon completion of erection of station lining in middle tunnel structures of track are built, in side tunnels passenger platforms, through openings are equipped with sliding doors.

EFFECT: technical result consists in providing development of structure and method of construction of three-vane column station, constructed by closed method of performing works with double-track main line tunnel, providing reduction of construction cost, improvement of manufacturability and speed of construction.
