METHOD FOR CONSTRUCTING A SUBWAY LINE WITH A DRAINAGE SYSTEM Russian patent published in 2022 - IPC E02D29/00 

FIELD: construction.

SUBSTANCE: invention relates to the construction of a subway, and in particular to drainage devices for tunnels and underground workings, which serve to remove water from subway structures. SUBSTANCE: method for constructing a subway line with a dewatering plant includes constructing a lining of a distillation tunnel using a closed method for work using a tunnel boring complex and creating a cavity for placing a dewatering plant to remove water from the tunnel below the level of rail tracks intended for the movement of subway trains. When driving a distillation tunnel of the subway line with the help of a tunnel boring complex at the lower point of the subway line, a constructive deepening of the distillation tunnel is created due to the progress of the tunnel boring complex, in which, during the construction of a concrete base for laying rail tracks, a water intake cavity is formed and a drainage installation is placed in it, while in a concrete the base along the rail tracks form trays for draining water into the water intake cavity.

EFFECT: increasing the speed of construction of subway lines by closed method for work and reducing the amount of work to place a drainage installation on the subway line due to the absence of additional underground workings.
