[0029] For the positioning of PHC pipe piles in floating solar power plants, the GPS positioning system on the floating pile driver is used to control the positioning of the pipe piles. However, using the positioning system on the pile driver can only roughly position the pipe piles, and it is impossible to precisely control the position, elevation, and verticality of the pipe piles. Moreover, the GPS positioning error on the pile driver is relatively large, resulting in uneven elevations of the tops of the rows of piles, uneven spacing between the pipe piles, and the verticality of the pile bodies exceeding the specification requirements. Repeated debugging is required during the installation process, leading to low construction efficiency.

[0030] In view of this, as Figure 1 and Figure 2 shown, this solution provides a rapid positioning device for PHC pipe piles to alleviate the above problems. This device includes a reference plate 100;

[0031] Two reference plates 100 are respectively detachably connected to the PHC pipe piles 300 at the head and tail ends in the length direction of the installation area through hoop clamps 200;

[0032] The two reference plates 100 are detachably connected by a string.

[0033] Before using this device for positioning, first position and sink two PHC pipe piles 300 at the head and tail ends in the length direction of the installation area respectively, and then measure and debug the elevation and verticality of the positioning piles. When the two positioning piles pass the re-inspection, then install the two reference plates on the positioning piles on both sides respectively, and then connect the two reference plates by a string, so as to use the position indicated by the string as the positioning mark for the PHC pipe piles 300 to assist workers in installing the PHC pipe piles 300.

[0034] As Figure 1 shown, regarding the shape and structure of the reference plate 100, as well as the installation method, specifically:

[0035] The reference plate 100 is in an inverted L shape, with the short side 110 abutting against the upper part of the PHC pipe pile 300, and the long side 120 is arranged parallel to the length direction of the PHC pipe pile 300;

[0036] There is a 90° angle between the short side 110 and the long side 120;

[0037] The long side 120 is provided with installation holes;

[0038] The hoop clamp 200 is provided with adjustment holes 210 that cooperate with the installation holes.

[0039] The hoop clamp 200 is provided with a plurality of adjustment holes 210 in the horizontal direction.

[0040] Specifically, after the positioning piles are installed, the short side 110 is closely attached to the upper end surface of the positioning piles, the long side 120 is arranged downward and parallel to the length direction of the PHC pipe pile 300, and is clamped on both sides of the long side 120 through the hoop clamp 200. The bolts pass through the adjustment holes 210 and the installation holes and are fixed and connected with nuts. At the same time, the size of the adjustment holes 210 is slightly larger than that of the installation holes to facilitate fine-tuning of the long side 120, making the positioning more accurate.

[0041] In this solution, a plurality of wire-hanging holes 121 are provided on the long side 120. After the positioning and installation of the reference plate 100 are completed, the hanging ropes are passed through the same wire-hanging holes 121 of the two reference plates 100, and are fixed after being straightened, so as to use the indicated position of the wire-hanging holes 121 as the construction reference.

[0042] In order to improve the positioning accuracy of the reference plate 100 and avoid affecting the overall stability of the device due to abnormal factors such as strong winds on the water, hoop clamps 200 are respectively provided at the upper and lower ends of the long side 120.

[0043] This solution has at least the following beneficial effects:

[0044] This device includes a reference plate 100; the two reference plates 100 are respectively detachably connected to the PHC pipe piles 300 at the head and tail ends in the length direction of the installation area through hoop clamps 200; the two reference plates 100 are detachably connected by a wire rope. The two reference plates are connected by the wire rope, so as to use the position indicated by the wire rope as the positioning mark of the PHC pipe pile 300, assisting workers in installing the PHC pipe pile 300, and significantly improving the pipe pile installation accuracy in the floating PV project. This device uses the reference plate and wire rope system to accurately calibrate the position, elevation and verticality of the pipe pile, solving the positioning error problem brought by the traditional GPS system. By finely adjusting the positioning piles before installation and using the calibrated reference plate for auxiliary positioning, the problems of uneven pile top elevation, inconsistent spacing and excessive verticality can be effectively avoided, thus improving the construction operation efficiency and engineering quality.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
