Description
Technical field
The utility model belongs to technical field of highway traffic, is related to a kind of cement concrete pavement detection technique, specifically relates to
And a kind of Void Under Concrete Pavement Slab identification robot.
Background technology
Road surface plate bottom empty is one of common failure mode of Old cement concrete, the reason for this problem occur master
Have：Plastic deformation, rainwash and the pumping of road deck bottom material, the weak link in structure design and maintenance are not
In time etc..When phenomenon occurs coming to nothing in road deck bottom, cement concrete pavement force modes will change, and particularly work as road
When panel Jiao Chu comes to nothing bottom, the road deck in position of coming to nothing is similar to cantilever slab, is taken off in the presence of vehicular load
The edge of empty position, which can be produced, can then produce excessive amount of deflection at larger concentrated stress, plate angle, course under cyclic loading will be led
Road surface is caused the diseases such as disconnected plate, the angle of rupture occur.
In order to accurately determine road surface working condition, to determine that the road surface in which section needs to take rationally at what time
Maintenance measure, this is accomplished by detection and accurately identification, and take row that science is carried out to the performance of concrete road surface
Effective handle measure；Road deck is repaired in time, prevents disease from further extending, to reduce manpower and materials and money
The waste in source.The harm that road surface plate bottom empty is caused in many early stage highway distresses is the most serious.Therefore, how in morning
A set of accuracy rate is developed in phase highway detection technique and method high, the good recognition methods of coming to nothing of recognition effect, and exploiting economy
The problem of effective punishment material and technology are present in the urgent need to address.
Method of Void is numerous under current road deck, and the principle that various methods set up institute's foundation is not quite similar, and has been used for
The method of Site Detection evaluation is broadly divided into three major types, and flexure differentiates class：Foundation stiffness comparative discriminant, deflection basin inverting evaluation
Method；Road GPR class：Two dimension or three-dimensional GPR；Sound wave class：Ultrasonic wave, Rayleigh wave method, vibration performance analytic approach,
Sound effect method.
From the point of view of the investigation detected to plat-bottom escape, several detection methods are primarily present following problem：
(1) flexure method detection is wasted time and energy, and accuracy of detection is low, and inversion algorithm is influenceed larger by ground surface material performance, and
And detection is representative poor, is not particularly suited for the Road Detection of project level；
(2) frequency of GPR and detection depth condition each other, and the interpretation of detection collection of illustrative plates is difficult；By dielectric permittivity
Influence is larger, and especially in the presence of water, the precision of detection will be reduced greatly, and detection device is expensive, especially to difference
Depth, the detection of pavement structure, which are generally required, coordinates the antenna of multiple frequency ranges could effective detection.
Pertinent regulations in current specification not to structure vacant analysis, single detection method can not accurately judge road
The continuous situation of structure sheaf, therefore someone used and examined simultaneously by using geological radar and two kinds of detection methods of FWD
Survey, then again by artificial subjective progress comprehensive descision.Analyzed from detection speed, be 5km/h using FWD, from people
Power angle analysis, FWD at least needs 3 people, and geological radar at least needs 2 people, and detection needs 5 people altogether, in summary side
The expenditure in face, FWD and the expenses of geological radar joint-detection are：Every 200 meters of FWD bicycle road
80~120 points are detected, every expense is about 50 yuan, it can thus be appreciated that bicycle road 400~600 points of every kilometer of detection, expense
For 2000~3000 yuan every kilometer, 1000 yuan every kilometer of geological radar adds up to 3000~4000 yuan every kilometer.Therefore no matter say
All it is at a relatively high from manpower use cost or testing cost.
The content of the invention
In order to overcome the shortcoming and deficiency that prior art is present, the purpose of this utility model is to provide a kind of cement concrete
Road surface plate bottom empty recognizes robot, is continuously struck by what computer control system was controlled by detecting to be respectively provided with below tractor
Hit device, dedicated microphone and position locator, the chatter baud that continuous knocking device is produced during on-site collection detection road surface
Levy, and by FEM model result of calculation, the cement pavement set up using BP neural network is come to nothing vibration acoustic characteristic
Storehouse, by Site Detection road surface acoustic characteristic and combines database result, determines that cement pavement comes to nothing state, realizes pavement distress
State is accurate, automatic identification, solves the above mentioned problem that existing cement concrete pavement detection technique is present.
Robot is recognized the utility model discloses a kind of Void Under Concrete Pavement Slab, it includes a detection and led
Draw car, and the computer control system set on detection tractor, be respectively provided with below detection tractor by computer
Continuous knocking device, dedicated microphone and the position locator of control system control.
Void Under Concrete Pavement Slab described in the utility model recognizes robot, is further characterized in that,
Described computer control system is provided with noise filtering unit, signal amplification unit, AD conversion unit, signal storage
Memory cell, FEM Simulation unit.
Described continuous knocking device is dragged by detection tractor and walked, and vibrates road deck with certain quality
And sound.
The road vibration acoustic characteristic is frequency of sound wave and the sound intensity.
The utility model Void Under Concrete Pavement Slab recognizes robot, is respectively provided with by detecting below tractor
Continuous knocking device, dedicated microphone and the position locator controlled by computer control system, during on-site collection detection road surface
The vibration acoustic feature that continuous knocking device is produced, and by FEM Simulation unit, it is different using numerical simulation calculation
The acoustic characteristic of operating mode of coming to nothing simultaneously combines artificial intelligence and realizes situation automatic identification of coming to nothing, and effectively improves cement pavement and comes to nothing inspection
Degree of testing the speed, is more accurately determined the size come to nothing, the order of severity and volume size etc. of coming to nothing, Grouting Treatment is provided to come to nothing
Effective foundation.
Because the utility model Void Under Concrete Pavement Slab continuous recognition machine device people detection speed is substantially carried
Per 100 km can save 25~350,000 yuan in height, testing cost.Therefore in terms of detection speed, labor intensive physical resources and financial resources,
Detect pavement distress than geological radar with falling using the continuous recognition methods of Void Under Concrete Pavement Slab of the present utility model
Two kinds of detection methods of hammer benkelman beams deflectometer, which have more, to have an economic benefit and social benefit, as Old cement concrete is open to traffic the time limit
Increase is, it is necessary to which the cement pavement of maintenance is more and more year by year, and market demand is increasing inside and outside the province, the utility model industrialization
Development prospect is optimistic, wide market.
