A section of a node of the station is a section with an arch roof and a straight wall of three underground floors, a first underground floor is a station hall floor 1, and a second underground floor is a platform floor 2 of a subway line A and a third underground floor is a platform floor 3 of a subway line B; and directions of the subway line A and the subway line B are orthogonal. Second lining structures of the first and second underground floors are firstly constructed, and after a shield tunneling machine is pushed through the station, the structure of the third underground floor is constructed by a reverse construction method. Thus, the present disclosure is conducive to improving the efficiency of overall construction, guaranteeing timely tunnel construction completion of two lines and hence timely track construction completion and electricity wiring completion.
