[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0026] See attached Figure 1 A measuring system for re-measurement of the position of an offshore fixed pile foundation comprises an adjustable buckle support 1 at the bottom, a horizontal adjustment support 4 in the middle and a real-time dynamic differential measuring instrument 6 at the top.

[0027] The real-time dynamic differential measuring instrument 6 is fixedly mounted on the horizontal adjustment support 4 through the first support rod 5. With the advantage of the length of the first support rod 5, the real-time dynamic differential measuring instrument 6 can be kept away from the pile foundation body, ensuring good satellite signal reception conditions and achieving precise positioning; a level bubble is arranged on the horizontal adjustment support 4, which can intuitively display its horizontal state, and can be accurately adjusted horizontally through a plurality of foot screws on the horizontal adjustment support 4; the horizontal adjustment support 4 is fixedly mounted on the adjustable buckle support 1 through the second support rod 3, and the adjustable buckle support 1 adopts a There are multiple support arms 11 with scales, and each support arm 11 is equipped with an adjustable position buckle 2. By adjusting the position of each buckle 2 on the support arm 11 and pressing each buckle 2 against the inner wall or outer wall of the pile foundation, the adjustable buckle support 1 can be tightly adapted and fixed on the top of the pile foundation of different diameters, and by observing the scales on the support arm, the adjustable buckle support 1 can be accurately made coaxial with the pile foundation (that is, the center of the adjustable buckle support 1 is aligned with the center of the pile foundation), so that the entire measuring system is firmly placed in the center of the pile foundation, thereby accurately measuring the coordinates and elevation of the center of the pile foundation.

[0028] For details, see the attached Figure 2The horizontal adjustment support 4 adopts a double-layer platform structure, that is, the horizontal adjustment support 4 includes a support upper platform 42 and a support lower platform 43 which are arranged opposite to each other up and down; a support column 431 is arranged at the top center position of the support lower platform 43, and the top of the support column 431 is an arc convex head, and a corresponding arc groove is arranged at the bottom center position of the support upper platform 42, and the arc groove is slidably matched with the arc convex head on the top of the support column 431 of the support lower platform 43, so that the support column 431 can support the support upper platform 42, and at the same time, the support upper platform 42 has full-range mobility around the arc convex head on the top of the support column 431; and a plurality of foot screws 45 are arranged on the support upper platform 42, A plurality of foot screws 45 are evenly distributed in a circle along the center of the support upper platform 42. In the present embodiment, the number of the foot screws 45 is 3. The bottom of the foot screws 45 acts on the support lower platform 43. By adjusting these foot screws 45, the horizontality of the support upper platform 42 can be adjusted (the counterclockwise rotation of the foot screws 45 will drive the corresponding part of the support upper platform 42 to rise, and the clockwise rotation of the foot screws 45 will drive the corresponding part of the support upper platform 42 to fall). In addition, a level bubble 44 is also provided on the support upper platform 42. When the bubble in the level bubble 44 is centered, it indicates that the support upper platform 42 is in a horizontal state, that is, it indicates that the real-time dynamic differential measuring instrument 6 installed on the support upper platform 42 is in a horizontal state.

[0029] A top stabilizing block 41 is provided at the top center of the upper platform 42 of the support, which is used to connect the second support rod 5. Specifically, a protrusion is provided at the center of the top stabilizing block 41, and the protrusion is provided with an external thread. The bottom of the second support rod 5 is provided with an internal thread, and then the bottom of the second support rod 5 is connected to the protrusion at the center of the top stabilizing block 41 through a thread. Further, the top protrusion of the second support rod 5 is provided with an external thread, and the bottom center of the real-time dynamic differential measuring instrument 6 is provided with an internal thread matching the external thread of the top protrusion of the second support rod 5, so as to realize the threaded connection between the real-time dynamic differential measuring instrument 6 and the top of the second support rod 5. Furthermore, a threaded hole is provided at the bottom center of the lower platform 43 of the support, which is used to be threadedly connected with the top of the first support rod 3.

[0030] See attached Figure 3 The adjustable buckle support 1 has a plurality of support arms 11. In this embodiment, preferably, 4 support arms 11 are included to form a cross support; or 6 support arms 11 can be used to form a cross support; a threaded connection portion 112 is provided at the center of the adjustable buckle support 1 (i.e., the intersection of all support arms 11) for threaded connection with the bottom of the first support rod 3. A buckle 2 is installed on each support arm 11, see the attached Figure 4The buckle 2 includes a buckle body 20, a clamping needle 22 and a locking bolt 21. The buckle body 20 is slidably mounted on the support arm 11 and can move along the support arm 11. The locking bolt 21 is installed in the threaded hole of the buckle body 20, and the threaded hole is communicated with the inner cavity of the buckle body 20, so that the locking bolt 21 can act on the support arm 11 in the inner cavity of the buckle body 20 to achieve locking of the buckle body 20 and the support arm 11. The clamping needle 22 is fixed at the bottom of the buckle body 20, and the clamping needle 22 is used to laterally tighten the inner wall or outer wall of the pile foundation; a standard scale accurate to millimeters is set on each support arm 11. By observing the scale on the support arm, the position of the buckle 2 on each support arm 11 can be accurately adjusted, and all the buckles 2 can be pressed against the inner wall or outer wall of the pile foundation, which can not only stably fix the adjustable buckle support 1 to the pile foundation, but also make the adjustable buckle support 1 coaxial with the pile foundation (that is, align the center of the adjustable buckle support 1 with the center of the pile foundation).

[0031] Before measurement, the measuring system of the present invention is placed above the fixed offshore pile foundation to be re-measured, and the position of the buckle 2 on the adjustable buckle support 1 is accurately adjusted according to the actual diameter of the pile foundation, so that the bottom of the measuring system can be tightly and firmly clamped in the center of the pile foundation, ensuring the accuracy of the subsequent measurement benchmark.

[0032] After installation, check the level bubble 44 on the level adjustment support 4. If the level bubble 44 shows that the system is not in a horizontal state, use the foot screw 45 on the level adjustment support 4 to make detailed adjustments. By rotating the foot screw 45, the height of each support point of the support is changed until the bubble in the level bubble 44 is centered, indicating that the measuring system has reached a horizontal state, providing a stable measuring plane for the measuring instrument and reducing measurement errors caused by tilt.

[0033] After the measurement system is horizontally calibrated, the real-time dynamic differential measuring instrument 6 on the top is started. The measuring instrument uses satellite positioning technology and differential algorithm, combined with its installation location advantage far away from the main body of the pile foundation, to effectively avoid interference from surrounding structures and accurately measure the coordinates and elevation information of the center of the pile foundation. During the measurement process, the system continues to maintain a stable state to ensure the continuity and accuracy of data collection.

[0034] After the measurement is completed, the measurement system is removed from the pile foundation. If other pile foundations need to be re-measured, the above operation process can be repeated. The tooling of the present invention significantly improves the safety and accuracy of the re-measurement of the position of the offshore fixed pile foundation through a unique structural design and operation process, providing a strong guarantee for the quality control of offshore engineering construction.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
