Abstract

The invention discloses a highway subgrade surface flatness measuring instrument which comprises bases, supporting frames arranged on the bases and a telescopic supporting frame, wherein the number of the bases is two; the supporting frames are arranged above the two bases, the number of the supporting frames is two, mounting frames are mounted between the two supporting frames, the number of the mounting frames is two, fastening devices are arranged on the mounting frames, and the number of the fastening devices is two; and the telescopic supporting frame is arranged in the mounting frames, and the telescopic supporting frame is in sliding connection with the mounting frames. According to the highway subgrade surface flatness measuring instrument, the accuracy of measuring the flatness of a highway subgrade surface is realized, so that the problem that wastes such as garbage and stones on the highway subgrade surface affects the measuring result of a testing wheel in the lateral measurement process of an existing highway subgrade surface flatness measuring instrument, and then the accuracy of data finally obtained by the flatness measuring instrument is reduced is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of high-speed road surface flatness detection, in particular to a high-speed road subgrade surface flatness measuring instrument. Background technique [0002] The road surface roughness tester is mainly suitable for the construction inspection, completion acceptance, and important data indicators of road maintenance of high-grade highways, urban roads, airport runways and other road surface projects. Expressway subgrade is one of the important indicators of pavement construction quality and service level. Uneven road surfaces will increase driving resistance and cause additional vibration to the vehicle. This vibration will cause driving bumps, affecting the speed and safety of driving, the stability of driving and the comfort of passengers. At the same time, the vibration will exert an impact force on the road surface, which will aggravate the damage of the road surface and the car, as well as the wear o...
