A kind of pavement flatness checking device and detection method
Technical field
The present invention relates to a kind of surface evenness detection auxiliary machine tool, more particularly to a kind of pavement flatness checking device
And specific detection method.
Background technology
Surface evenness refers to the deviation of the concavo-convex amount of road surfaces longitudinal direction.Surface evenness is pavement evaluation and road surface
An important indicator in delivery receiving acceptance, what is mainly reflected is the planarization of vertical section of road surface section curve.Work as vertical section of road surface
During section curve relative smooth, then it represents that road surface is opposed flattened, or flatness is relatively good, on the contrary then expression flatness relative mistake.
Good road surface then requires surface evenness also to get well.Surface evenness is one of the key technical indexes for evaluating pavement quality, it
It is related to the safety of driving, the size and service life of impact force, the road surfaces of out-of-flatness can increase suffered by comfortable and road surface
Car resistance, and vehicle is produced additional effect of vibration.This effect of vibration can cause vehicle pitching, influence the speed of driving
And safety, the steady and passenger's for influencing to drive is comfortable.
Now in the method for detecting surface evenness, generally it is aided with clearance gauge measurement using three meters of rulers and is detected.
In practice process, needed according to frequency and testing requirements is detected as defined in specification to multiple sections, the road surface of multiple structure sheafs
Roughness measurement is carried out, cumbersome and time consuming, measurement efficiency is low, and measuring accuracy is poor.
Chinese patent application CN101644023A discloses a kind of detection method of road-surface evenness, using accelerometer detection due to
The relative displacement of laser range finder caused by road bump, and then angle of inclination is measured, surface evenness is calculated, main solution
The detection of surface evenness certainly under < 25km/h.Chinese patent CN205775763U discloses a kind of surface evenness detection dress
Put, manufacture cost is relatively low.
Though there are some at present for the surface evenness relevant research of detection and device, all there are certain,
It is difficult to ensure that accuracy of detection, the maintenance cost of some detecting systems are again too high in the case that if testing cost is relatively low.
In view of above-mentioned existing surface evenness detection there are the defects of, the present inventor is based on being engaged in such product design
Manufacture abundant for many years practical experience and professional knowledge, and coordinate the utilization of scientific principle, actively it is subject to research and innovation, to found one
Kind pavement flatness checking device and detection method, make it have more practicality.By constantly research, design, and through repeatedly
After studying sample and improving, the present invention having practical value is created finally.

It is equipped with spirit level.
As preference, foregoing pavement flatness checking device, the test section has further included vernier scale button, described
Vernier scale button is arranged on the top of the vernier scale, and the vernier scale button is connected with vernier scale contact by metal connector
Connect.
By the detection method of pavement flatness checking device of the present invention, including following operating procedure, by evenness of road surface
Degree detection device is placed on measured road surface, and the recess of moving cursor ruler to measured road surface, presses vernier scale button, make
The vernier scale contact ground of vernier scale bottom, is fixed on the quarter that the vernier scale pointer on vernier scale is directed toward on pantograph at this time
Degree, the numerical value shown by this scale are the cup depth of recess for this.
As preference, foregoing detection method, the pantograph is p-type structure, the vertical portion of the pantograph and institute
State the parallel setting of vernier scale;The vernier scale pointer is directed toward at the arc of p-type structure pantograph, the arc of p-type structure pantograph
Scale is indicated at shape.
By above-mentioned technical proposal, pavement flatness checking device of the invention and detection method are at least with following excellent
Point:
Pavement flatness checking device proposed by the present invention measures the depth at road surface depression by the principles of magnifying tags, into
And surface evenness is measured, measurement error caused by avoiding reading existing for conventional manual measurement not smart;And detect when without
It need to bend over, alleviate the labor intensity of inspector.
The ruler body of the present invention is formed using knockdown almag, can be folded, compact, is convenient for carrying, magnalium
Alloy is not easy to be corroded as the main material for preparing, and service life is longer.
