Problems solved by technology

[0003] When testing the flatness of the subgrade and pavement of the highway, it is necessary to place the equipment on the road for testing. During the testing process, the staff needs to clean up the stones, tree trunks and other sundries on the tested road in advance, otherwise the equipment There will be a certain range of ups and downs when passing through the stones, which will have a great impact on the authenticity of the final measurement, making the detection results unrealistic, resulting in the need for the staff to check the position of the road surface where the data deviates.

Abstract

The invention discloses highway subgrade pavement flatness detection equipment which structurally comprises moving wheels, a detection assembly, a detection head, a display screen, a mounting frame, a main body, a side plate, a limiting bolt and a clearing device.When the highway subgrade pavement flatness detection equipment is used, sundries such as stones and tree trunks on a pavement are cleared and stressed through a collection receiving hopper, and after the sundries are received, the detection module is used for detecting the pavement flatness of the highway subgrade; vibration generated when a pressing rod collides with sundries is absorbed through a buffering assembly, then a collecting receiving hopper is supported through cooperation of a sliding groove supporting piece, the collecting receiving hopper can stably clean the sundries and tree trunks on the road surface, and the flatness of the roadbed road surface of the road is detected through a detection wheel; when the detection wheel is in contact with a road surface bulge, the detection wheel drives the connecting rod to retract inwards to extrude the pressure spring, the pressure spring retracts inwards to extrude the measurement sensor after being pressed, the measurement sensor can measure the bulge degree of the road surface, and accurate data guidance is provided for further repairing of the road.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a roadbed road surface smoothness testing device. Background technique [0002] The subgrade is the foundation of the road surface. It is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide the necessary conditions for driving operations. It has sufficient strength and good stability, and its surface should meet the requirements of smoothness, compactness and anti-skid. When testing the flatness of road subgrade and pavement, the areas that need to be improved are as follows: [0003] When testing the flatness of the subgrade and pavement of the highway, it is necessary to place the equipment on the road for testing. During the testing process, the staff needs to clean up the stones, tree trunks and other sundries on the tested road in advance, otherwise the equipment There will be a certain range of ups and downs...
