AI Technical Summary
Existing roadbed settlement monitoring devices are difficult to measure settlement data at multiple locations simultaneously, are complex to operate and lack accuracy, affecting the overall deformation judgment of the roadbed, and are inconvenient to use in complex environments.
A portable roadbed settlement rapid observation device was designed, which adopts multi-level adjustable telescopic components and scale structure to form multi-point measurement and can quickly adapt to different measurement needs. It includes a vertical plate, first and second telescopic components and limit locking components, forming a rectangular three-dimensional frame to ensure measurement stability and accuracy.
It enables intuitive comparison of settlement data at multiple points, improves the convenience and accuracy of measurement, is applicable to complex terrain, provides comprehensive subgrade condition assessment, and reduces measurement errors.

Abstract
Claims
1. A portable device for rapid observation of subgrade settlement, characterized in that: include A vertical plate, the top of which is hinged with at least two first telescopic members; The second telescopic component is rotatably disposed at the end of the movable part of the first telescopic component away from the vertical plate; Both the first telescopic member and the fixing part of the second telescopic member are provided with scales; A limiting locking component is provided at the top of the vertical plate to lock the rotation angle of the first telescopic component at 90°; When the vertical plate, the first telescopic member, and the second telescopic member are in contact with each other, they are stacked in parallel. When the first telescopic member and the second telescopic member rotate 90° relative to their respective rotation axes, they together form an n-shaped three-dimensional frame structure.
2. The portable device for rapid observation of roadbed settlement according to claim 1, characterized in that: A disc is fixed at the center of the top of the vertical plate. The limiting locking component is a fastening bolt, which is rotatably disposed on the circumferential side of the disc. When the first telescopic component rotates 90° to a horizontal state, the fastening bolt is threadedly engaged with the fixing part of the first telescopic component.
3. The portable rapid roadbed settlement observation device according to claim 2, characterized in that: A baffle is provided at the end of the movable part of the first telescopic member away from the vertical plate. The baffle is arranged perpendicular to the length direction of the movable part and is used to limit the maximum rotation angle of the second telescopic member, so as to keep the second telescopic member in contact with the baffle when it rotates 90°.
4. The portable rapid roadbed settlement observation device according to claim 3, characterized in that: The bottom of the vertical plate is fixed with a base, and the side of the base that is in contact with the roadbed is evenly provided with serrations that can be inserted into the roadbed. The serrations are set as conical protrusions.
5. The portable rapid roadbed settlement observation device according to claim 4, characterized in that: The shortest length of the first telescopic component when retracted is less than the length of the vertical plate, the shortest length of the second telescopic component when retracted is less than the shortest length of the first telescopic component when retracted, and its maximum length when unfolded is greater than the distance between the top of the vertical plate and the roadbed surface.
