Road engineering pavement quality detection device

Abstract

The invention discloses a road engineering pavement quality detection device, and belongs to the field of pavement detection equipment. A detection contact is attached to a pavement to perform a multi-direction rotating path movement process, so that the detection contact performs a large-range, multi-direction and direct detection process on the pavement in the area, and in the detection process, through mutual contact and extrusion of the outer bag, the inner bag and the balloon, automatic lateral displacement and deviation of the detection contact at the wave crest position of the road surface are achieved, the integrity of the detection contact is effectively guaranteed, meanwhile, the wave crest road condition is reflected to the pressure sensor, and by combining the detection result of the detection contact and the detection result of the pressure sensor, pavement roughness change can be directly and accurately displayed. Compared with the prior art, the detection method provided by the invention has the advantages that the road surface roughness change can be directly and accurately displayed, and compared with the prior art, the detection method has better fitness with an actual complex and changeable use environment, so that the detection result is more accurate.

Description

technical field [0001] The invention relates to the field of road surface detection equipment, and more specifically, relates to a road engineering pavement quality detection device. Background technique [0002] After highway construction, highway supervisors need to test the construction quality of the highway. The testing items include road surface smoothness, road surface water permeability, road surface roughness and so on. Quality inspection has played an important role in ensuring the quality of highway engineering construction, improving the quality of road use and investment benefits, and will continue to play an irreplaceable role in future engineering construction and management. [0003] The most direct contact with the road surface is the vehicle tire. Among them, the road surface roughness has a direct impact on the sliding resistance, deformation and wear of the vehicle tire during driving, and affects the safe driving of the vehicle, so it is very important. ...

AI Technical Summary

Problems solved by technology

[0004] Existing detection of road surface roughness is generally through the instrument sliding on the road surface to determine the anti-skid ability of the road surface, or using a test car to test the friction coefficient of the road surface; however, the sliding of the testing instrument and the driving detection of the test car on the road There is a single situation, and in the actual process, the track of the vehicle wheel is unpredictable, it is difficult to directly and accurately measure the road surface roughness
