Accompanying drawing explanation
Fig. 1 is overall sectional view of the present utility model;
Wherein: 1, particulate formula bituminous concrete, 2, Chinese style bituminous concrete, 3, emulsification concrete bond plaster, former 4, cement concrete pavement.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of cement concrete pavement becomes base layer structure, and described cement concrete pavement comprises particulate formula bituminous concrete 1, Chinese style bituminous concrete 2, emulsification concrete bond plaster 3, former cement concrete pavement 4 and roadbed; Described particulate formula bituminous concrete 1, Chinese style bituminous concrete 2, emulsification concrete bond plaster 3 and former cement concrete pavement 4 are from top to bottom successively set on roadbed.
Further, cement concrete pavement becomes base layer structure, and its construction method is:
One, pavement deflection detects
The supporting capacity of cement concrete pavement adopts deflection testing to evaluate, the performance condition of main reflection 3 aspects: (1) integrated carrying ability, and the modulus of elasticity calculating sub-layer mainly through deflection test in plate and rigidity composition analysis reflects; (2) void beneath slab conner situation, by plate angle deflection test, judges according to deflection value; (3) joint slab merit rating, calculates flexure difference and load transfer coefficient by two deflection sensors striding across transverse joint.Test flexure is a very important basic work; First, draw entire road plate floor map: then carry out deflection test to 4 angle points of every block plate, joint slab ability adopts flexure ratio method to calculate, evaluates, and carries out classification gather, as the foundation of plate process test data.
Two, the process of bad plate
Cement concrete pavement is that the cement concrete slab separated by shrinkage joint combines (size of plate is 3.5m × 5m).Old cement concrete uses through long-time, just there will be that some cement concrete slabs are squished by wheel, crush, rupture, arrisdefect etc., and when " changing black in vain " constructs, these problems all must solve.If indivedual cement concrete slab badly broken, can not continue to use, then old plate thoroughly must be removed, Deteriorated concrete pavement plate is excavated outward transport, then again build the cement concrete that label is not less than former road surface.When old plate is broken: 1. will note not using sledgehammer, artificial or that pneumatic pick is broken method can be adopted, more adopt loader to go down to shovel dress after fragmentation and can adopt the method manually taken out of by rubble, with the bed course avoiding construction disturbance darker; Do not damage adjacent concrete slab when 2. will note fragmentation, also will remove the end, hole after the removing of rock ballast soil simultaneously and loosen the soil, note whether there is cavity etc. below adjacent panels, also must by same method process.Again, during concreting, carry out vibrating in strict accordance with code requirement, plucking, the construction such as maintenance, finally cut the shrinkage joint with adjacent panels as early as possible, in case heat causes concrete slab swelling cracking.
Three, along the section of connecing construction
Owing to cement concrete pavement being wanted black top concrete, thus cause new old asphalt concrete pavement elevation inconsistent along the section of connecing at former cement concrete pavement and the longitudinal of asphalt concrete pavement, therefore will carry out the two along the section of connecing construction processing.Processing method is that cement concrete slab joint being about 10 ~ 15m is pounded by the method for process bad plate and removed, then again by along connecing high range request casting cement rigid pavement.For ensureing the construction quality along meeting place, steel mesh reinforcement and dowel bar to be laid in new casting cement rigid pavement toward contact, forming steel concrete subbase.Laterally the suitable section of connecing is because area is little, the magnitude of traffic flow is less, and the method for grain formula bituminous concrete in laying on Old cement concrete can be taked to make elevation consistent.
Four, joint treatment
Shrinkage joint process is the important procedure in base treatment construction.First adopt joint cutter to carry out joint-cutting cleaning to gap, then use bitumen crack-pouring machine to asphalt reperfusion matizhi in the seam after cleaning.Foreign material in seam are mainly thoroughly removed by seam machine raked joint, will ensure that the seam that certain saw clears out deeply will have enough degree of depth generally to want 8 ~ 10cm at least during raked joint.To clean clean after raked joint in time and carry out the cementation of fissures as early as possible, in order to avoid foreign material enter gap again.Asphalt reperfusion matizhi in the shrinkage joint cleared out, has generally been come by special matizhi pouring machine.Will adjust pouring machine before the cementation of fissures, the coal tar ins and outs making it to flow out are greasy, even.The cementation of fissures will have been come by special operating personnel, and cementation of fissures hourly velocity wants slow, ensure that the bitumastic in stitching is evenly closely knit, make it slowly to staticize to solidify.
Five, the construction of manhole cover
Because road surface is raised, need that adjustment is carried out to the manhole cover on former road surface and raise well reinforcing.Raise the method for reinforcing and can adopt steel bar concrete reinforcement method.For not affecting asphalt concrete pavement construction, manhole cover raises reinforcing should in the end carry out before spreading out by one deck bituminous concrete.First should check the region of cement concrete pavement well lid surrounding 30 ~ 40cm and manually abolish the dark left and right of 30cm, remove dregs, the Scheme of Strengthening provided by design department and drawing have propped up template, have put into reinforcing cage, by the good manhole cover base of design height pad, and make it with elevation is consistent along connecing around to surrounding elongation line, be not less than the cement concrete on former road surface subsequently to well lid surrounding cast label, vibrate by specification, maintenance etc., ensure workmanship.
Six, the process of cement concrete substrate surface and health cleaning
Also have the work that one important before spilling mulseal, paving geotextiles, carry out process and the health cleaning work of cement concrete substrate surface exactly, the outstanding corner angle of the dribs and drabs on Old cement concrete all will be removed.For ensureing planeness, the pavement strip on former road surface also all must manually be removed.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
