AI Technical Summary

Technical Problem

In existing roadbed settlement testing, the equipment is not placed horizontally, which leads to deviations in the test results. Impurities and protrusions on the roadbed surface affect the flatness and compaction, resulting in low testing efficiency and poor accuracy.

Method used

A roadbed survey unit was designed, which includes a settlement detection mechanism, pneumatic components, a leveling unit, and a sweeping plate. The pneumatic components drive the detection plate to move, the support components move the sweeping plate synchronously, and the leveling unit ensures that the equipment is level. The sweeping plate cleans impurities, and sensors are used to detect the settlement depth and perform comparative analysis.

Benefits of technology

It improves the accuracy and efficiency of roadbed settlement detection, avoids data deviation caused by equipment tilting, simplifies the operation process, and reduces manual intervention.

Abstract

This invention discloses a roadbed survey unit, detection system, and analysis method for addressing road hazards. The unit includes a survey box with a settlement detection mechanism inside for detecting roadbed settlement depth. A horizontal adjustment unit is located diagonally at the bottom of the survey box. The settlement detection mechanism includes a detection plate, the top of which is driven downwards by a pneumatic component. This invention relates to the field of road surveying technology. This roadbed survey unit, detection system, and analysis method for addressing road hazards, by incorporating a settlement detection mechanism, utilizes a pneumatic component to move the detection plate vertically downwards. The moving plate moves synchronously through the pulling of a traction rope and the cooperation of a support component. This not only enables subsequent roadbed settlement detection but also improves the accuracy and efficiency of the detection process by cleaning the test surface with a sweeping plate before settlement detection.
