[0020] Example: Figs. 1 to 3 As shown: A rapid positioning device for installing a high-strain method sensor on a foundation pile includes a positioning plate 1 and a hinge plate 2. The positioning plate 1 is vertically arranged, and a first mounting hole 3 and a second mounting hole 4 are respectively provided on the top and bottom of the positioning plate 1; wherein, the first mounting hole and the second mounting hole are used to install the strain sensor. Fig. 2The first mounting hole and the second mounting hole are vertically corresponding and both are through holes with a size of 6-8mm. The hinge plate 2 is hinged to the positioning plate 1 through a hinge 14. The purpose of the arrangement is to provide a precise position of the acceleration sensor and facilitate storage. The hinge plate 2 is provided with a third mounting hole 5 in the center. The third mounting hole is used for mounting the acceleration sensor. The first mounting hole 3, the second mounting hole 4 and the third mounting hole 5 are all circular. The centers of the first mounting hole 3 and the second mounting hole 4 are on the same vertical line. The height distance between the center of the third mounting hole 5 and the centers of the first mounting hole 3 and the second mounting hole 4 is the same, that is, the center of the third mounting hole is on the horizontal plane of the midpoint between the centers of the first mounting hole and the second mounting hole. The horizontal distance between the centers of the first mounting hole and the third mounting hole is 60-80mm. The vertical height distance between the center of the first mounting hole and the center of the second mounting hole is 28-48mm.

[0021] As shown in Fig. 2 In this embodiment, the positioning plate 1 is also provided with a retractable positioning ruler 6 to adaptively adjust the extension length of the positioning ruler 6 according to the size of the foundation pile outer diameter. Specifically, the positioning ruler adopts a soft and coiled storage structure with a scale line. The end of the positioning ruler 6 is also provided with a lifting ring 15. The arrangement can facilitate the positioning of the reference point, so as to measure the position of the sensor to be installed on the foundation pile. In actual foundation pile detection operation, different diameters of the foundation pile require different positions of the sensor to be installed on the foundation pile. In the preferred embodiment, the positioning plate 1 is provided with a cavity 7. One side of the cavity 7 is provided with a cover plate 8 connected with the positioning plate 1 through screws. The purpose of the cover plate is to facilitate the combined installation of the internal coiled structure. One side of the cover plate 8 is provided with a through hole 9. The purpose of the through hole is to facilitate the positioning of the ruler, and the thickness of the lifting ring is greater than the width of the through hole. The lifting ring is always outside the through hole of the cover plate. The cooperation of the reel, the winding drum and the scroll spring can facilitate the storage and extension of the positioning ruler. The scale positioning ruler can adjust the installation height of the sensor according to the size of the foundation pile outer diameter, which is convenient to operate and has higher practicality. It further ensures the accuracy of the sensor position on the foundation pile.

[0022] As shown in Fig. 3As shown: wherein, in the cavity 7 is also provided with winding structure 10. Specifically, the winding structure 10 includes reel 11, winding drum 12.
