Description

A kind of Steel Bridge Deck epoxy asphalt pavement comes to nothing disease rapid detection method
Technical field
It comes to nothing disease rapid detection method the present invention relates to a kind of Steel Bridge Deck epoxy asphalt pavement, belongs to bridge machinery skill Art field.
Background technique
Paving steel bridge deck is currently a global problem.Orthotropic Steel Bridge Deck is since flexibility is larger, in driving lotus Under the action of the factors such as load, wind load, temperature change, the stress of pave-load layer and deformation are sufficiently complex, mat formation with conventional road structure And its structural support of roadbed, base is compared, paving steel bridge deck deflection is big, and various factors is also easy to produce vibration and deformation；Stress It is unfavorable, easily form hogging moment；Steel plate and asphalt pavement interlayer bonding are difficult, and interlayer shear stress is very big；Thus, deck paving It is easier come to nothing Deng early diseases occur.Since paving steel bridge deck is usually traffic main artery, the volume of traffic is heavy, and does not replace therewith Other selections in generation, will usually not break off a friendship to the reparation of its disease fastly or.And disease of coming to nothing is once occur, it is inevitable fast-developing at The larger range of pit slot for being more difficult to quickly repair, pit-hole.Therefore, detect to come to nothing disease and to be punished be current in time Urgent problem to be solved.
Currently, the basic blank in Method of Void field about paving steel bridge deck is constantly in no detection means situation. Drop hammer deflection meter (FWD) and Ground Penetrating Radar (GPR) technology is mostly used to come to nothing to detect interlayer in bituminous pavement field.FWD pairs Pavement structure impact force is larger, if may be damaged to bridge structure for paving steel bridge deck, thus, FWD technology is uncomfortable Preferably it is used for paving steel bridge deck vacant analysis.GPR can be used for the interlayer detection on concrete bridge deck pavement, road surface etc..The country carried out The exploration come to nothing using Ground Penetrating Radar detection paving steel bridge deck interlayer.By multiple practical application, it is found that steel plate sends out radar The frequency electromagnetic waves of injection have a high-strength reflection interference effect, almost 100% it is fully reflective, therefore be difficult to be suitable for The vacant analysis of paving steel bridge deck.There is scholar's research to carry out vacant analysis to paving steel bridge deck using mechanical wave, although principle can Row, but its detection efficiency is too low.
