technical field

The utility model relates to a tool for detecting the smoothness of road surface, in particular to a continuous detection device for local area smoothness of road surface, which can be used for self-checking the smoothness of road surface in the process of highway construction, and can also be used for local road surface during highway completion acceptance continuous detection.

Background technique

The smoothness of road surface is directly related to the construction quality of the road and involves the safety of driving vehicles. Therefore, the detection of road surface roughness is a very important index in the evaluation of road quality. At present, the testing equipment for the roughness of highway pavement is mainly divided into two categories: section type and reaction type. Cross-section detection equipment is an instrument for measuring the unevenness of the road surface. This test method requires destructive sampling of the road; reaction type detection equipment is used to measure the bumps of the vehicle caused by the unevenness of the road surface, which is directly felt by drivers and passengers. Different people will have different feelings about the flatness index obtained, and this detection method is greatly influenced by subjectivity. With the continuous advancement of technology, there are now advanced automatic test equipment, such as profile analyzers, road surface roughness data acquisition system measurement vehicles, camera measurement systems, etc. These equipment require users to have a high level of science and technology. The above-mentioned equipment has high cost, high use and maintenance costs, is rarely equipped in the construction team, and is not suitable for use in the construction process.

Contents of the invention

The purpose of this utility model is to provide a continuous detection device for local area smoothness of highway pavement, which is used for self-checking of road surface smoothness during highway construction, which facilitates construction and improves construction quality, and can also be used for partial road surface during highway completion acceptance continuous detection.

The utility model is realized in the following way: a continuous detection device for local area flatness of highway pavement includes a horizontal support and a measuring trolley, the horizontal support is provided with surveying paper and a spirit level, the level instrument is arranged on the frame body on the side of the horizontal support, and the outriggers are arranged At the four corners at the bottom of the horizontal support; the measuring trolley includes a horizontal wheel and a measuring wheel, the measuring wheel equipped with a surveying pen is connected to the horizontal wheel, the horizontal wheel moves along the frames on both sides of the horizontal support, and the mapping paper is fixed inside the frame on one side , the surveying pen records the moving traces on the surveying paper. the

The remarkable effect of the utility model lies in that the utility model provides a detection device for the flatness of the local area of the highway pavement. The utility model can manually push the measuring trolley on the horizontal support to draw the already drawn surface on the surveying paper with the surveying pen. The curve graph of the measured road surface can intuitively reflect the smoothness of the measured road surface through the scale on the surveying paper. The length of the horizontal support is designed between 3-4 meters. The utility model can continuously detect the 3-meter-long road surface at one time. Its structure is simple, the manufacturing and maintenance costs are low, and there is no requirement for the operator's education level, and the detection results are intuitively reflected. On the surveying paper, you can read along with the measurement. The application is convenient during the construction process, which not only improves the construction quality, but also greatly improves the work efficiency, reduces the waiting time for the measuring equipment, significantly reduces the production cost, and has good application effect and economic benefits.
