[0068] In the present embodiment, the jacking device 50 is a piezoelectric ceramic jacking device 50 or a small screw jack or a hydraulic jack that can be directly purchased on the market; four are arranged, which are distributed on the four corners of the base 10 to jacking at different angles; in this way, when the pier 101 settles at any angle, the jacking device 50 can be adjusted; more specifically, the angle sensor 30 is arranged on the pier 101, which can be but not limited to including the static level type inclinometer or the fiber grating inclinometer that can be directly purchased on the market; the angle sensor 30 detects the included angle between the pier 101 pier body axis and the design axis and outputs a first detection signal; the above-mentioned first detection signal includes one or a combination of the tilt angle signal of the included angle and the tilt direction signal of the pier 101;

[0069] In the present embodiment, the pressure sensor 40 is arranged between the support column 21 and the base 10 to monitor the pressure between the support column 21 and the base 10 and output a second detection signal; the above-mentioned second detection signal includes the pressure signal between any one support column 21 and the base 10, so that the pressure supported by each support column 21 of the pier 101 can be monitored; which facilitates accurate control of compensation filling in the later stage;

[0072] Through the above technical scheme, the inclination of the pier 101 / beam body can be detected by the angle sensor 30; when the inclination angle is greater than 0.5°, the signal controller receives the first signal and performs data analysis, selects the working mode to determine the jacking amount, and sends a start instruction to the jacking device 50 to drive the corresponding angle jacking device 50 to jacking slightly, thereby adjusting the horizontal posture of the beam body; further, the signal processor receives the second signal and performs data analysis, selects the working mode and determines the predicted bearing pressure, so that the pressure sensor 40 ensures uniform distribution of the load at four corners and avoids local overload.

[0073] The data storage mode stores the inclination angle and the jacking amount measured by the angle sensor 30 at any time and transmits them to the central control room through the remote interaction module, so that the staff can remotely observe the deviation correction of the bridge 102; thus, it can be determined whether human intervention is needed according to the operation manual.
