Technical background
In existing cement concrete pavement, the bridge floor, under effects such as temperature, weather, produce stress, cause stretching, distortion or torsional deflection, therefore just the shrinkage joint must be set for fear of the cement concrete plate; Perhaps owing to can not construct continuously, and produce constuction joint.Because the existence of shrinkage joint or constuction joint in cement concrete pavement, the bridge floor plate, when road surface, bridge floor have rainwater to exist or flow, rainwater will be from the road surface, seam seepage to road surface, bridge deck structure of bridge floor plate, causes in road surface, the bridge deck structure ponding or road surface, bridge deck structure water content to increase.
Because ponding or water content increase in the road surface, bridge deck structure, the intensity of the surface layer, basic unit, subbase, bed course etc. of road surface, bridge deck structure is descended; On the other hand, under the sound load action of vehicle, make ponding or seepage water inlet in road surface, the bridge deck structure produce flowing pressure, destructions such as road pavement, bridge deck structure generation are washed away, scour.Under the effect of intensity decline and sound water pressure, cause road surface, bridge floor and under basic unit, the destruction of bed course, under the effect of flowing pressure, the basic unit, the course that destroy wash away, scour takes away, make and lose support under the panel, cause panel unsettled, under the effect of vehicular load, panel produces destructions such as cracking, fracture.Therefore, the destruction of cement concrete pavement, bridge floor is developed to other position of plate gradually mostly from the plate seam crossing.Cause cement concrete pavement, bridge floor weak point in application life, stationarity, the comfortableness of driving are poor, the speed and the safety of influence driving.Though this also is that cement concrete pavement, bridge floor are more cheap than flexible pavement, bridge floor, and that cement concrete pavement, bridge floor are used is fewer and feweri, and asphalt concrete pavement, bridge floor are used one of increasing reason.
In order to prevent cement concrete pavement, the percolating water road pavement of bridge floor plate seam, the destruction of bridge floor, generally is now the seam that adopts asphalt seal road surface, bridge floor plate, perhaps on the road surface, the adverse effect that produces of the seam crossing of the bridge floor plate percolating water that adopts the method for stiffener to tackle cement concrete pavement, deck joint.But adopt the asphalt seal seam, because road surface, temperature decline when bridge floor has ponding or flowing water, pitch and road surface, bridge deck shrink, seam is opened, the sealing effect of pitch is with regard to variation, surface water on road surface, the bridge floor will be in road surface, bridge deck structure seepage, therefore, the effect of pitch joint seal is undesirable.And the seam crossing of road surface, bridge floor plate is when adopting the method for stiffener to handle, and the antiseep of basic road pavement, bridge floor plate seam does not play great effect.
From existing road surface, the Deck Water Leakage test case, the percolating water of road surface, deck joint is that cement concrete pavement, bridge floor surface water seepage enter position the most serious in road surface, the bridge deck structure, and the existing joint seal method that adopts all can not play the purpose of anti-seep water fully.And highway, bridge flashing product, and use it for and prevent that road surface, bridge floor surface water seepage from entering road surface, bridge floor internal construction and concrete grammar and yet there are no report in highway, bridge engineering.
