Background In the construction of the superposition assembly type subway station, the side wall is used as a core bearing and lateral pressure resisting component, and the verticality of the side wall directly determines the stress rationality, the spatial dimension precision and the subsequent assembly connection quality of the station structure. After the side wall is installed, multiple loads such as side pressure of concrete pouring are required to be borne, inclination deviation is easy to generate, and if perpendicularity exceeds standard, the problems of structural stress concentration, waterproof sealing failure, overlarge joint clearance with adjacent components and the like can be caused, so that the long-term use safety of the station is seriously influenced. The current verticality adjustment of the side wall mainly depends on two traditional technologies, namely, manual deviation measurement by means of a theodolite, adjustment by pushing through a manual screw rod support or a jack, inclined support fixation after adjustment, and a simple mechanical support system which can only provide fixed supporting force and has no automatic monitoring and dynamic adjustment capability. In an actual construction scene, the traditional technology has the remarkable limitations that the height of the side wall is higher (about 7 m), the manual measurement deviation is large, dynamic inclination in the pouring process cannot be monitored in real time, manual adjustment depends on the experience of workers, uneven force control is easy to cause local stress concentration of the side wall to generate cracks or excessive/insufficient adjustment, the stress of the side wall is dynamically changed in the concrete pouring process, the traditional fixed support cannot respond to the deviation change in time, secondary inclination is easy to occur, the adjustment efficiency is low, the adjustment of a single side wall takes 2-3 people to cooperate, the time is 1-2 hours, and the high-efficiency requirement of assembly type construction is difficult to match.
