Example Embodiment

[0037] The present invention will be further described in detail below in conjunction with the drawings.

[0038] Reference figure 1 The present invention provides a road surface smoothness measurement device, including a measurement component 1, a beam 2, a limit component 3, and a detection device 4. The beam 2 is horizontally arranged above the ground, and the measurement component 1 is arranged below the beam 2 and can face the road. To measure the flatness of the road surface, the limit component 3 is set at both ends of the beam 2 and can keep the beam 2 parallel to the road surface, and the detection device 4 is set on the beam 2 and can be obtained when the measurement component 1 measures the road surface flatness Data is collected.

[0039] When using the measuring device to measure the flatness of the road surface, move the measuring device to the selected measurement area through the beam 2; after reaching the measurement area, use the limit component 3 to keep the beam...

Abstract

The invention relates to the technical field of engineering detection devices, in particular to a road surface flatness measuring device. The road surface flatness measuring device comprises a measuring scale, a firing pin, a nail cap and a detection device, the measuring scale extends in the horizontal direction, the firing pin is uniformly arranged below the measuring scale along the extending direction of the measuring scale, the upper end of the firing pin faces upwards to extend into the measuring scale, the nail cap is arranged on the upper end face of the firing pin and is used for preventing the firing pin from being separated from the measuring scale, the firing pin drives the nail cap to slide in the measuring scale along the axis direction of the firing pin, the detection device is arranged on the measuring scale and measures the moving distance of the firing pin in the measuring scale, so that the effects of conveniently measuring the flatness of the road surface and saving time and manpower are achieved.

Description

technical field [0001] The invention relates to the technical field of engineering testing devices, in particular to a road surface smoothness measuring device. Background technique [0002] At present, the smoothness is an important indicator in the evaluation of the construction quality of new pavement and the maintenance quality of old pavement. It reflects the longitudinal unevenness of pavement and driving comfort. [0003] The existing road surface smoothness detection process is to use the three-meter ruler method to directly detect the maximum gap between the ruler and the road surface to reflect the smoothness of the road surface. [0004] The above-mentioned existing technical solutions have the following defects: the existing process of detecting the flatness of the road surface requires the staff to perform multiple measurements on the distance between the ruler and the ground to obtain the flatness of the road surface, which will waste a lot of time and manpowe...
