[0031] Before measurement, the measurement system of the present application is placed above the offshore fixed pile to be re-measured, the positions of the buckles 2 on the adjustable buckle support 1 are accurately adjusted according to the actual diameter of the pile, so that the bottom of the measurement system can be tightly and stably clamped at the center position of the pile, and the accuracy of the subsequent measurement reference is ensured.

[0032] After installation is completed, the level bubble 44 on the horizontal adjustment support 4 is observed, if the level bubble 44 shows that the system is not in a horizontal state, the foot screw 45 on the horizontal adjustment support 4 is used for fine adjustment, the height of each support point of the support is changed by rotating the foot screw 45, until the bubble in the level bubble 44 is centered, indicating that the measurement system has reached a horizontal state, providing a stable measurement plane for the measuring instrument and reducing measurement errors caused by inclination.

[0033] When the measurement system is horizontally calibrated, the real-time dynamic differential measuring instrument 6 at the top is started, the measuring instrument uses satellite positioning technology and differential algorithm, and combines the advantages of the installation position far away from the pile body, effectively avoids the interference of the surrounding structure, and accurately measures the coordinate and elevation information of the center of the pile. During the measurement process, the system continuously maintains a stable state, ensuring the continuity and accuracy of data acquisition.

[0034] After measurement is completed, the measurement system is removed from the pile. If other piles need to be re-measured, the above operation process can be repeated.
