The subgrade high slope monitoring and measuring device includes a plurality of receiving units, a receiving column 2, and a plurality of laser rangefinders 3. The plurality of receiving units are sequentially arranged at intervals from top to bottom along the slope surface of the slope 7. The receiving unit includes a connecting member 11, a mounting shaft 12, a driving assembly 13, and a reflector 14. The connecting member 11 is fixedly arranged on the slope 7; the mounting shaft 12 is vertically arranged and slidably penetrates through the connecting member 11; the driving assembly 13 is arranged on the connecting member 11, and the driving assembly 13 is used to drive the mounting shaft 12 to slide; the reflector 14 is fixedly arranged on the mounting shaft 12.

The laser rangefinder 3 is located on one side of the receiving column 2 facing the plurality of receiving units, and the laser rangefinder 3 is fixedly arranged on the receiving column 2.

[0027] Compared with the prior art, for the subgrade high slope monitoring and measuring device provided by the present utility model, the laser beam emitted by the laser rangefinder 3 hits the corresponding reflector 14, so as to measure the distance from the reflector 14 to the laser rangefinder 3. When the slope 7 loosens and slides, the position of the receiving unit changes, and the distance measured by the laser rangefinder 3 also changes, so as to realize the monitoring of the slope 7. When the reflector 14 is not at the preset height, the driving assembly 13 drives the mounting shaft 12 to slide, so as to adjust the height of the reflector 14 until the reflector 14 is adjusted to the preset height, thus avoiding the problem that the height of the reflector 14 cannot be adjusted after installation.

[0028] In this embodiment, the reflector 14 is perpendicular to the laser beam emitted by the laser rangefinder 3.

In this way, the connecting ring 132 sleeved in the annular groove 1311 can restrict the movement of the driving sleeve 131 in the vertical direction, so that the driving sleeve 131 is rotatably arranged on the connecting member 11.

[0031] In some embodiments, the above-mentioned feature receiving unit can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the receiving unit further includes a limiting ring 15 and a second fixed shaft 16. The limiting ring 15 is slidably sleeved outside the connecting shaft 133. The two ends of the second fixed shaft 16 are respectively fixedly connected to the limiting ring 15 and the mounting shaft 12. The limiting ring 15 is fixedly connected to the mounting shaft 12 through the second fixed shaft 16, so that the limiting ring 15 can slide synchronously with the mounting shaft 12 in the vertical direction. The connecting shaft 133 can restrict the rotation of the mounting shaft 12 through the limiting ring 15, so that the mounting shaft 12 only has the freedom of movement in the vertical direction.

[0032] In some embodiments, the above-mentioned feature connecting shaft 133 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , a limiting portion 1331 protruding outward is provided on the side wall of the connecting shaft 133.

Referring to Figure 4 , the connecting sleeve 17 is in a vertical prism-shaped structure, and the connecting sleeve 17 has a through hole 171 for the mounting shaft 12 to slide through. In this way, when the connecting sleeve 17 is inserted into the slope 7, the rotation of the receiving unit can be restricted by the connecting sleeve 17, so that the reflector 14 can be kept facing the preset direction.

[0036] In some embodiments, referring to Figure 1 , the monitoring and measuring device for the high slope 7 of the roadbed further includes a mounting column 4 and a monitoring camera 5. One end of the mounting column 4 is fixedly connected to the top end of the receiving column 2, and the other end is located on the side of the receiving column 2 facing the receiving unit.
