Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a roadbed slope detection device. Background Art

[0002] The roadbed slope refers to the slope connecting the ground on both sides of the roadbed cross section. There are embankment slopes and cutting slopes, which are important factors affecting the stability of the roadbed. The shape of the slope is often built into a single slope, a broken line, and a step shape in the roadbed. The slope of each slope section is expressed by the ratio of the height difference between the upper and lower points on the slope section diagram to the horizontal distance. In the roadbed structure, the shape of the slope and the steepness of the slope have an important impact on the stability of the roadbed and the engineering cost.

[0003] At present, most slope measurements are carried out using artificial plumb lines, slope gauges, etc., which are slow, labor-intensive, and unable to automatically monitor the roadbed slopes of different sections for a long time. When there are bumps or pits in the measurement environment, the accuracy of the measurement results will be reduced, errors will easily occur, and the accuracy of the test results will be affected, making the applicability low.
