FIELD: construction.SUBSTANCE: invention refers to construction of three-arched underground stations of a column type, mainly of deep embedding; with that, it is possible to construct such stations at shallow embedding using semi-closed and closed methods, also at the subsequent construction of intermediate underground stations of deep and shallow embedding in new operating lines without violation of their operation. The three-arched underground station of a column type includes side station tunnels consisting of assembled liners of annular outline, a middle station tunnel with a permanent liner of the arch with a tie bar and a flat tray, supporting structures consisting of columns and internal longitudinal non-split connection straps on columns, which are installed in the space of side station tunnels, and a passenger platform. Supporting structures are installed on edges of the platform. Outside the side station tunnels there installed are external longitudinal non-split supporting beams, connection elements of side station tunnels and the middle tunnel, which include the internal non-split connection straps on the columns, units of assembled liners of annular outline and external longitudinal non-split supporting beams are congruent.EFFECT: improving use efficiency of underground space, reducing labour intensity, duration and material consumption for construction of an underground station; improving static operation of the design; increasing passenger safety.12 cl, 18 dwg |
