Description
Technical field
It the utility model is related to pavement preservation technical field, more particularly to a kind of cement concrete pavement faulting of slab ends reparation knot
Structure.
Background technology
Faulting of slab ends is the vertical discrepancy in elevation of adjacent panels at seam or crack, is one of Common Diseases of cement concrete pavement
If repaired not in time, comfortableness, the security of driving are not only substantially reduced, and make with the repeated stock of wheel load power
With, the cracking of whole road deck will be caused, or even there is fragmentation, and then the conevying efficiency of highway is influenceed, cause huge economy
Loss and bad social influence.
Cement concrete pavement faulting of slab ends Treatment Methods are issued in Ministry of Communications at present《Highway cement mixes
Solidifying soil surface maintenance technology specification》In punishment to faulting of slab ends be that different modes is highly taken according to faulting of slab ends, for the discrepancy in elevation<12mm
Faulting of slab ends, using polishing method；For the discrepancy in elevation>12mm faulting of slab ends, using tar sand reparation.But both modes respectively have it not
Foot：Method is polished, remediation efficiency is low, easily causes the microcrack under processing panel, reduces slab strength；Tar sand reparation, color
It is uncoordinated, influence attractive in appearance, easily cause the collimation error to driver.Also have in practice using epoxy resin mortar or cement mortar in engineering
Repair, epoxy resin mortar Repair strength is high, and bond performance is good, but construction process requirement is high, and cost is high, less economical；Cement mortar
Rupture strength is low, shrink it is larger, easily there is desciccation crack, service life is short, and repair thickness it is thicker (at least 20mm with
On), curing period length, open to traffic time length.
The utility model patent of Application No. 201420263305.7, which discloses a kind of it, includes faulting of slab ends sinking plate, faulting of slab ends phase
Adjacent plate, adhesive phase, repair materials layer, the cement concrete pavement faulting of slab ends repair system of caulking material layer, but due to faulting of slab ends
Sinking plate forms groove, easy ponding with faulting of slab ends adjacent panels junction, and ponding can infiltrate into repair materials and connect with faulting of slab ends sinking plate
Place is met, so as to destroy the repair system.
Utility model content
The utility model aims to overcome that deficiency of the prior art, there is provided a kind of intensity is high, the strong water of waterproof ability
Cement concrete faulting repairs structure.
The utility model is achieved through the following technical solutions：A kind of cement concrete pavement faulting of slab ends repairs structure, bag
The gap between faulting of slab ends sinking plate, faulting of slab ends adjacent panels faulting of slab ends sinking plate and faulting of slab ends adjacent panels is included, mortar is provided with the gap
Basic unit, mortar basic unit upper end are provided with tack coat, and it is recessed that the faulting of slab ends sinking plate close to the upper surface in gap is provided with first
Groove, first groove are additionally provided with the second groove on the faulting of slab ends sinking plate in the gap direction, first groove and the
Mutually from addition to repair layer, the repair layer be covered in tack coat, the first groove, the second groove upper end between two grooves.
Preferably, first groove cross section is rectangle.
Preferably, the cross section of second groove is rectangle.
Preferably, it is provided with water-repellent paint between second groove inner wall and repair layer.
Preferably, the repair layer is equal with the one end of the second groove away from gap towards one end of the second groove.
Preferably, the upper end section of the repair layer is arc, and its near faulting of slab ends adjacent panels junction with faulting of slab ends phase
Adjacent plate is parallel.
Preferably, the mortar basic unit is modified cement mortar basic unit.
Preferably, the tack coat is epoxy resin glue bonding layer.
Beneficial effect
The beneficial effects of the utility model are：Screed and tack coat are set in gap, avoids the occurrence of and gushes the diseases such as slurry
Evil；First groove is set, ensures the bonding strength between repair materials and faulting of slab ends sinking plate；Second groove is set, played very strong
Impermeable role, improve repair structure service life.
Brief description of the drawings
Fig. 1 is the schematic diagram that cement concrete pavement faulting of slab ends repairs structure.
Embodiment
Cement concrete pavement faulting of slab ends as shown in Figure 1 repairs structure, including faulting of slab ends sinking plate 1, faulting of slab ends adjacent panels 2, wrong
Gap 3 between platform sinking plate 1 and faulting of slab ends adjacent panels 2, modified cement mortar basic unit 4, modified cement mortar are provided with gap 3
The upper end of basic unit 4 is provided with epoxy resin glue bonding layer 5, and it is recessed that faulting of slab ends sinking plate 1 is provided with first on the upper surface in gap 3
Groove 7, the cross section of the first groove 7 is rectangle, and faulting of slab ends sinking plate 1 upper surface of first groove 7 on the direction of gap 3 is also set up
Have the second groove 8, the cross section of the second groove 8 is also rectangle, between the first groove 7 and the second groove 8 mutually from.
Epoxy resin glue bonding layer 5, the first groove 7, the upper end of the second groove 8 are also covered with repair layer 6, the material of repair layer 6
Material is identical with former road surface, is provided with water-repellent paint between the inwall of the groove 8 of repair layer 6 and second, can effectively avoid ponding
To repairing structural damage, its service life is improved, repair layer 6 is towards one end of the second groove 8 and the second groove 8 away from gap
3 one end is equal, ensures the bonding strength between repair layer 6 and faulting of slab ends sinking plate 8.
The upper end section of repair layer 6 is arc, and flat with faulting of slab ends adjacent panels 2 near its junction with faulting of slab ends adjacent panels 2
