[0025] See also Figures 1 to 3A geotechnical structure displacement monitoring auxiliary device includes: a plug-in sleeve 100 and a mounting frame 200, wherein the plug-in sleeve 100 is used to be buried in the rock and soil, and the plug-in sleeve 100 is threadedly connected with a mounting rod 110; the mounting frame 200 is vertically arranged at the upper end of the mounting rod 110, and the mounting frame 200 is horizontally provided with a rotating rod 210, and the side wall of the mounting frame 200 is provided with a fixing sleeve 220, one end of the rotating rod 210 is threadedly connected to the fixing sleeve 220, and the middle part of the rotating rod 210 is fixedly connected with a mounting plate 230, and the mounting plate 230 is fixedly provided with a reflective sheet 240, and when the rotating rod 210 is rotated by an external force, the reflective sheet 240 can deflect relative to the mounting frame 200.

[0026] When using the auxiliary device for monitoring displacement of geotechnical structures of the above structure, first use an electric drill to drill a hole of corresponding depth and diameter on the rock structure to be monitored, then knock the plug sleeve 100 into the hole, and finally use a tool such as a wrench to tighten the installation rod 110 into the plug sleeve 100. Among them, rotating the installation rod 110 can correspondingly adjust the horizontal direction of the reflective sheet 240, and rotating the rotating rod 210 can correspondingly adjust the vertical direction of the reflective sheet 240, so that people can adjust the installation angle of the reflective sheet 240 according to different installation points, so that the reflective sheet 240 at different positions can better face the monitoring station, so as to improve the effect of geotechnical structure monitoring. In addition, the threaded matching of the plug sleeve 100 and the installation rod 110 has a simple structure, quick and stable installation, and can effectively improve the efficiency of the installation of the geotechnical structure monitoring point.

[0027] It is understandable that the device is not only applicable to the monitoring of geotechnical structures, but also to the monitoring of concrete structures, which will not be described in detail here.

[0028] See also Figure 1 Further, the plug sleeve 100 is an expansion screw sleeve, the mounting rod 110 is an inner bolt matched with the expansion screw sleeve, and a clamping cap 120 is provided between the inner bolt and the mounting frame 200. Specifically, when in use, the inner bolt is screwed into the expansion screw sleeve for a stable installation, and the clamping cap 120 abuts against the upper end of the expansion screw sleeve, which is conducive to separating the reflector 240 from the observation interface.

[0029] See also Figures 1 to 3 Furthermore, the installation frame 200 is a rectangular frame, the rotating rod 210 is located in the middle of the rectangular frame, and the width of the reflective sheet 240 is smaller than the width of the rectangular frame. Specifically, when the rotating rod 210 is screwed into the fixing sleeve 220, the width of the reflective sheet 240 is smaller than the width of the rectangular frame, which is conducive to the reflective sheet 240 being able to move horizontally inside the rectangular frame, so that the reflective sheet 240 can rotate relative to the installation frame 200 to tilt toward the monitoring station.

[0030] See also Figures 1 to 3Furthermore, the mounting frame 200 is provided with a through hole opposite to the fixing sleeve 220, and one end of the rotating rod 210 is penetrated by the through hole and connected with a nut 250, so that people can rotate the nut 250 by tools such as a wrench, thereby driving one end of the rotating rod 210 to screw into or out of the fixing sleeve 220, which is conducive to driving the reflective sheet 240 to rotate.

[0031] See also Figure 3 Furthermore, the rotating rod 210 includes a first rod portion 211 and a second rod portion 212 which are sleeved with each other, the mounting plate 230 is connected to the first rod portion 211, one end of the first rod portion 211 is connected to the fixing sleeve 220, the other end of the first rod portion 211 is provided with a threaded hole, one end of the second rod portion 212 is connected to the threaded hole, and the other end of the second rod portion 212 passes through the through hole. Specifically, during installation, the first rod portion 211 is first threadedly connected to the fixing sleeve 220 so that the reflective sheet 240 can be built into the interior of the installation frame 200, and then one end of the second rod portion 212 is screwed into the threaded hole of the first rod portion 211, so that the second rod portion 212 and the first rod portion 211 finally form an integrated structure, which is convenient for people to install the reflective sheet 240 inside the installation frame 200, and also convenient for people to drive the first rod portion 211 to rotate by rotating the second rod portion 212. In order to improve the connection strength between the first rod portion 211 and the second rod portion 212 , after the second rod portion 212 is installed, the outer peripheral wall of the second rod portion 212 and the first rod portion 211 in contact may be welded by a welding gun.

[0032] See also Figures 1 to 3 Furthermore, the upper end of the mounting frame 200 is connected with a circular ring portion 260, and the circular ring portion 260 and the mounting frame 200 are an integrated structure, so that people can apply force to rotate the mounting rod 110 through the circular ring portion 260, so that the mounting rod 110 can be quickly screwed into the plug sleeve 100. The circular ring portion 260 and the mounting frame 200 can be fixed together by welding.

[0033] Furthermore, the surfaces of the mounting frame 200 and the annular portion 260 are coated with a red paint layer, which is conducive to marking the monitoring installation position, so as to facilitate the monitoring personnel to conduct inspections, and also to form a reminder mark to prevent accidental touches. In some embodiments, the mounting plate 230 can be made of a steel plate, which has good structural strength and a smooth surface, which is conducive to people cleaning or wiping stains on the surface of the steel plate, thereby keeping the installation position of the reflector 240 tidy.

[0034] Furthermore, the reflective sheet 240 is bonded to the mounting plate 230 by glue, so as to improve the stability of the installation of the reflective sheet 240 and reduce the falling off of the reflective sheet 240. In some embodiments, the reflective sheet 240 can also be fixed by magnetic attraction. A plurality of magnets evenly distributed along a circumferential direction can be arranged on one side surface of the mounting plate 230. The plurality of magnets and the reflective sheet 240 are fixed by multi-point adsorption. Under this structure, the reflective sheet 240 can be disassembled, and the orientation on the mounting plane can be adjusted, which is conducive to improving the use effect of the reflective sheet 240.

[0035] See also Figures 1 to 3 Furthermore, a mounting portion 270 is connected to the lower end of the mounting frame 200 , and the mounting portion 270 is welded to the upper end of the mounting rod 110 , so that the mounting frame 200 can form an integrated structure with the mounting rod 110 .
