Hoisting construction method for large reinforcement cage

The invention provides a hoisting construction method of a large reinforcement cage, which comprises the following steps: S1, establishing a diaphragm wall reinforcement cage model according to a design drawing to obtain the gravity center position of the reinforcement cage; s2, calculating the arrangement position of a lifting point according to a bending moment balance law; s3, the main crane and the auxiliary crane are moved to the hoisting position, and shackles of hoisting points of the reinforcement cage are installed according to the calculation result; s4, steel reinforcement cage trial hoisting; s5, the main crane lifts a hook, and the reinforcement cage is converted into an inclined state; s6, the main crane slowly hooks, the reinforcement cage is converted into a state perpendicular to the ground, and the auxiliary crane loosens the hook; according to the method, the optimal arrangement position of longitudinal and transverse lifting points is calculated by utilizing the principle that the bending
