In particular, in step S3, in order to ensure that the lateral cylinders 203 have good supporting effect and to take into account that the wall structure of the concrete shear wall 110 may be damaged due to too much jacking force of the lateral cylinders 203, the first lateral support a is firstly supported; the cylinder driving system of the lateral cylinder 203 adopts a PLC controller, the extension displacement of the lateral cylinder 203 adopts a stay wire type displacement sensor (not shown in the figure), the speed of the lateral cylinder 203 in the initial extension stage is high, and the cylinder extension control adopts a speed control and displacement control method; when the displacement of the lateral oil cylinder 203 reaches about 190 mm, the oil cylinder extension control mode adopts a force control mode, and the lateral oil cylinder 203 can keep constant supporting pressure.

P can be calculatedBThe control system automatically identifies the jacking force in the control process of controlling the force of the lateral oil cylinder 203; pAThe value is set according to the wall thickness of the concrete shear wall 110, so that within the control system, PAFor inputting values, the target value P can be displayed on an external display screenAInputting, the system automatically calculates PBMagnitude of value and in force control process, by PBThe variable is used as the index of force control, thereby achieving the effect of constant force and automatic feedback control.
