Description

A road surface smoothness detection device

technical field

The invention relates to the technical field of road detection, in particular to a road surface smoothness detection device.

Background technique

Road surface roughness refers to the deviation value of the unevenness in the longitudinal direction of the road surface. Road surface roughness is an important index in road surface evaluation and road surface construction acceptance. The service life affects the speed and safety of driving. Therefore, in order to reduce the vibration and impact force, increase the speed of driving and increase the safety of driving, the road surface should maintain a certain degree of flatness.

There are still some deficiencies in the existing road surface roughness detection equipment, and the specific deficiencies are:

1. The existing road surface roughness detection equipment can mark the unevenness of the road surface during the detection process, which only obtains the position information of the uneven road surface. For the shape information of the uneven road surface area and the height of the raised road surface and the concave road surface The device cannot detect the depth information, which provides less help for subsequent road repairs, and the detection quality is low.

2. There will be objects such as stones and leaves on the road surface. These objects will interfere with the detection results of the road surface flatness testing equipment. Usually, it is necessary to manually clean the road and then carry out the flatness testing, which will increase the labor cost. It also leads to poor detection effect.
