DOUBLE-LEVEL SINGLE-VAULT TRANSFER STATION UNIT OF DEEP SUBWAY Russian patent published in 1999 - IPC

FIELD: construction. SUBSTANCE: transfer station unit includes two stations located under single vault and transfer unit with service rooms, side supports, top and inverted domes from prefabricated reinforced concrete lining adjusted to rock, tracks, platforms of upper and lower levels. Supports for floor under tracks and platforms of upper level are made in the form of longitudinally arranged split column-girder complexes consisting of prefabricated reinforced concrete columns installed at rated spacing into sleeves of longitudinal cast-in-situ reinforced concrete foundation girders. The latter are installed within rigid base laid on inverted dome of lining for equalling of nonuniform deformations of inverted dome along station length. Installed on tops of column are prefabricated reinforced concrete beams. Installed under tracks of upper level are transverse reinforced concrete beams resting with their one end on girder, and with their other end movable resting on cantilever of cast-in-situ concrete support of lining. Space between longitudinal cast-in-situ foundation girders and rigid base is filled with noncombustible mashed material to height equalling the rated deformations of inverted dome. EFFECT: higher efficiency of structure, exclusion of dangerous deformations of main bearing structures, reduced load on inverted dome. 2 dwg
