TECHNICAL FIELD

[0001] The present application relates to the technical field of flatness measuring devices, in particular to a flatness measuring device for the arch top protection layer of an arch-shaped culvert on a highway. BACKGROUND

[0002] The flatness measuring device for the arch top protection layer of an arch-shaped culvert on a highway is an intelligent device for quickly and accurately detecting the flatness of the surface of the arch top of a culvert. It usually uses laser scanning, 3D imaging or high-precision sensor technology, and combines an automatic walking mechanism to achieve full-arch-top coverage measurement. The device can adapt to the curved surface of the arch, collect three-dimensional point cloud data in real time, and calculate the flatness deviation (such as mean square deviation and maximum height difference) through an algorithm to generate a visual heat map and a detection report. The precision can reach ±0.5mm, which is significantly better than traditional manual detection methods. The core advantage of the device is its high efficiency (10 minutes to complete 100 meters of detection), safety (avoiding high-altitude manual work), and support for data cloud storage and remote analysis, making it widely used in the construction acceptance and maintenance monitoring of highways and railway tunnels.

[0003] The existing flatness measuring device for the arch top protection layer of an arch-shaped culvert on a highway lacks an effective damping mechanism during mobile measurement. When the mobile vehicle carrying the measuring device travels, external vibrations are directly transmitted to the measuring mechanism, causing significant deviation in the data collected by the sensor and affecting the accuracy of the measurement results.
