Working principle: When using it, the subgrade to be detected first needs a necessary condition. The elevation along the centerline of the road needs to be a known condition. Before using the detection ruler body, it is necessary to use a level instrument or other instruments to collect and process the elevation points of the centerline; After the elevation of points distributed along the center line, place the detection ruler body on the subgrade surface to be detected, perpendicular to the center line of the road, and parallel to the horizontal line of the road, and then adjust the first ruler body 1 and the second ruler body 2 at both ends. The height of a seat 9 is leveled using the level bubble 3 to ensure that the upper surfaces of the first ruler body 1 and the second ruler body 2 are on the same elevation plane; Measure the distance from the first ruler body 2 to the top of the road bed. After determining the distance from the first ruler body 1 and the second ruler body 2 to the road bed top, organize the data into a book, and then determine the first ruler body 1 and the second ruler body 1. The "foot width" of the body 2; the distance between the first foot body 1 and the second foot body 2 to the top of the road bed is determined, and the cross slope value of the road bed at this place can be accurately calculated, the elevation of the center point is determined, and the width of the foot is determined , can accurately calculate the elevation of the point where the distance from the ruler to the top of the road bed has been measured. The calculation process is as follows: the distance from a certain point to the top of the road bed ÷ the distance from the center point to this place x 100% = the cross slope value at this place ;Central point elevation+central point chi to roadbed top distance+foot width=detection ruler body elevation; The push block 12 drives the two second fixed blocks 11 to move into the two second moving grooves 10. At this time, the two second fixed blocks 11 break away from the two draw-in slots 15, and then drive the two second fixed blocks 11 through the two third push blocks 16. The third fixed block 14 moves into the two third moving grooves 13, and the two first supports 9 can be folded through the two second rotating shafts, and then the moving block 5 is driven by the first push block 7 to break away from the fixed groove 8 and move to the second moving groove 8. In a moving groove 4, the first ruler body 1 and the second ruler body 2 can be folded through the first rotating shaft at this time. When the height needs to be adjusted, pull the two first supports 9 up or down, The seat 9 drives two slide plates 19 to slide in the two slide grooves 18, and the two slide plates 19 drive the two pointers 22 to move. Through the cooperation of the pointer 22 and the scale 23, the moving distance of the slide plate 19 can be known and accurately The height of the two first supports 9 is adjusted, and the first ruler body 1 and the second ruler body 2 are driven by the two first supports 9 to adjust the height.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
