Pavement flatness monitoring device and detection method thereof

Abstract

The invention relates to a pavement flatness monitoring device and a detection method thereof. The device comprises a bracket, a supporting arm, a pulley and an angle sensor, wherein the bracket is arranged on the pavement and can move; the supporting arm is hinged to the bracket; the pulley is connected to the bottom end of the supporting arm and is arranged on the pavement in a sliding way; through the pulley, the supporting arm is driven to rotate around a hinging position; the angle sensor is connected to the supporting arm; through the angle sensor, the inclination angle value of the supporting arm when the bracket moves on the pavement is measured; and through the angle value, the displacement of the pulley in a vertical direction can be obtained to realize the detection of the pavement flatness. By use of the angle sensor, the inclination angle value of the supporting arm is firstly measured through the angle sensor, then, the displacement of the pulley in the vertical directionis calculated, so that whether bulges and pits are in the presence on the pavement or not can be judged, whether a flatness requirement is met or not is judged, and the device is convenient in detection.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a road surface smoothness monitoring device and a detection method thereof. Background technique [0002] Pavement roughness reflects the flatness of the profile curve of the pavement profile. When the profile curve of the pavement profile is relatively smooth, it means that the road surface is relatively flat, or the flatness is relatively good, otherwise it means that the flatness is relatively poor. The smoothness of high-grade highway pavement has an impact on driving speed, driving safety, driving comfort and vehicle life. [0003] The paving construction of the pavement surface layer construction is carried out according to the preset benchmark, and most of the paver machines have automatic leveling devices. wave. [0004] In the prior art, it is generally necessary to stick a level on the road surface to check the smoothness of the road surface after the road constr...
