Description

Technical Field

[0001] This utility model relates to the technical field of highway deflection detection, specifically a highway deflection detection device. Background Technology

[0002] A deflectometer is a device used to determine the rebound deflection value of a road surface. It evaluates the overall strength of the road surface by measuring the total vertical deformation or vertical rebound deformation value generated at the wheel gap position on the roadbed or road surface under a specified standard axle load. There are two commonly used deflectometers: the Beckman deflectometer and the falling weight deflectometer.

[0003] The Beckman deflectometer consists of a dial gauge base, a dial gauge, two levers, and a lever base. Utilizing the lever principle, it indirectly measures the deflection basin's settlement value by measuring the road surface's rebound after the load is removed. Existing Beckman deflectometers have separate levers, requiring on-site assembly and installation of the lever base at the lower end of the levers, which takes considerable time. Furthermore, Beckman deflectometers come in 3.6m and 5.4m sizes, but the existing levers have fixed lengths, necessitating the assembly of a new Beckman deflectometer when switching sizes, thus impacting testing efficiency.
