The invention provides an automatic adjusting system and method for perpendicularity of side walls of a stacked assembly type subway station. The system comprises a push-pull adjustment execution device, the push-pull adjustment execution device comprises at least two electric push-pull rods evenly arranged at the top of the prefabricated side wall, and the two ends of each electric push-pull rod are hinged to one side of the underground diaphragm wall and the top of the prefabricated side wall correspondingly and used for driving perpendicularity adjustment of the prefabricated side wall; the perpendicularity monitoring device is used for collecting vertical inclination angle data of the prefabricated side wall in real time; and the central control device is in signal connection with the perpendicularity monitoring device and the push-pull adjustment execution device and is used for receiving the inclination angle data, calculating perpendicularity deviation, automatically generating an adjustment instruction according to the deviation and controlling the telescopic movement of the electric push-pull rod so as to dynamically correct the perpendicularity of the prefabricated side wall. Dynamic monitoring and automatic correction of the perpendicularity of the side wall can be achieved, errors and stress unbalance caused by manual intervention are avoided, it is ensured that the perpendicularity of the side wall meets the standard requirement in the whole pouring process, the adjusting efficiency is improved, and the construction risk is reduced.

The application discloses a main bridge steel structure construction method and relates to the technical field of bridge construction. The specific steps comprise the following steps: dividing regions, installing baffle plates and pier columns, installing steel pipe piles and platform support columns, installing inter-column supports and sliding beams to form sliding tracks, repeatedly constructing the south bank, completing platform support covering a river, installing lower chord rods and lower bridge decks, installing upper chord rods and upper bridge decks, installing upper-layer cantilevers and lower-layer cantilevers, assembling sliding units, repeatedly assembling sliding units until closure, hoisting the last sliding unit and completing installation of the main bridge steel structure. The construction method can reduce operation risks, shorten construction period, save materials and reduce costs.
