Asphalt pavement stress monitoring device

Abstract

The invention relates to the technical field of pavement monitoring, and discloses an asphalt pavement stress monitoring device which comprises a pavement, a construction groove is formed in the surface of the pavement, a supporting seat is arranged at the bottom of the construction groove, a fixed ring is arranged at the top of the supporting seat, a rotating ring is arranged in the fixed ring, and a movable ring is arranged in the fixed ring. The rotating ring and the movable ring are fixedly connected through a connecting block, a plurality of connecting pipes connected end to end transversely penetrate through the interior of the rotating ring, spiral digging cones are fixedly arranged at the tail ends of the connecting pipes, a cavity is formed in the rotating ring, and a clamping mechanism used for fixing the connecting pipes is arranged in the cavity; rockers are fixedly arranged at the bottom of the side wall of the rotating ring. A mounting groove is formed in the side wall of the construction groove through a spiral digging cone, and a shell is arranged in the mounting groove. According to the asphalt pavement stress monitoring device, the position of the mounting groove is dug in the side direction, so that the stress monitoring device can accurately monitor the stress change of the pavement.

Description

technical field [0001] The invention relates to the technical field of road surface monitoring, in particular to an asphalt road surface stress monitoring device. Background technique [0002] Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed with mineral materials. At present, the asphalt pavement is exposed to the natural environment, and the performance of the asphalt pavement is greatly affected by the changes in the natural environment and the rolling of external vehicles, especially the stress. Therefore, the stress monitoring of the asphalt pavement will be carried out. [0003] The existing asphalt pavement stress monitoring device needs to be laid inside the asphalt pavement for use, but there are great difficulties in laying the stress monitoring device. For example, the asphalt pavement is directly excavated for the installation groove, and the stress monitoring device is placed inside the installation groove. Then, it ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an asphalt pavement stress monitoring device, which adopts the position of the installation groove excavated laterally, so that the stress monitoring device can accurately monitor the stress change of the road surface, and solves the problem of laying the stress monitoring device at present. It is inconvenient inside the road surface, resulting in inaccurate monitoring results
