Description
One, technical field
The present invention relates to pavement engineering and job practicess thereof such as highway construction, especially cement concrete is provided with the honeycombed cement surface concrete membrane and the job practices of tack coat.
Two, background technology
1, the cement concrete pavement cover, add laying method
Cement concrete pavement is one of main road surface form of generally adopting of highway and urban road, when cement concrete pavement needs cover, when overlaying, selects following dual mode at present for use:
One, on cement concrete pavement, overlay cement concrete.In this case, the material of overlay still is a cement concrete, and the cement concrete of overlay belongs to compact structure, and it forms by cast, Vibration Technology.Stress according to overlay can be divided into convolution overlay and separate type overlay, and the convolution overlay is meant that overlay and the Portland Cement Concrete Surface Course under it bond together, common bearing load effect; The separate type overlay is meant that overlay separates with Portland Cement Concrete Surface Course under it, stratification separately, and following cement concrete pavement plays basic unit.
Two, on cement concrete pavement, overlay bituminous concrete.At this moment the material of Jia Puing is a bituminous concrete, and the structure of this form often is called as " morning-night " or " changing black in vain ".Need to spill on the cement concrete surface below asphalt of penetrate layer and adhesion coating pitch before the asphalt concrete, with bituminous concrete and the Portland Cement Concrete Surface Course secure bond that guarantees to overlay, with effects such as common bearing loads.
2, the problem of Cun Zaiing
When overlaying cement concrete layer, traditional portland cement concrete belongs to fragile material, and deformability is little, and is easy to crack, and to supporting situation sensitivity, the road surface easily produces disease, and when constructing in addition, concrete shrinkage is big, also can cause concrete cracking.
When overlaying bituminous concrete, because the bituminous concrete intensity that overlays is low, must well could guarantee the operate as normal of overlay with the bottom bonding, though adhesion coating, saturating layer generally adopt, but because the modulus of elasticity of bituminous material and cement concrete material great disparity is big, temperature deformation coefficient difference is bigger, be difficult for accomplishing bonds well generally speaking, this also is short basic reason " morning-night " general service life.
Three, summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy construction adopts the formed cement concrete of honeycombed cement concrete to be provided with the honeycombed cement surface concrete membrane and the job practices of tack coat.
The present invention adopts single-stage to join or the second wife's rubble that breaks, make it evenly to mix with cement, sand, water, the honeycombed cement concrete material of hole is rich in formation, the machinery that employing has leveling, jolt ramming function paves, utilize spreading machine leveling certainly, guarantee the closely knit, smooth of surface layer from the jolt ramming function.The porous concrete material has kept the high strength of cement class material; Because porous concrete belongs to framework dense structure, therefore contraction reduces simultaneously, and the strain during destruction increases---deformability strengthens, and presents plastic property during destruction, has increased the adaptive capacity of surface layer; The employing of multi-pore structure makes the road surface can permeable, noise reduction, has improved the service performance of cover, adopts the paver construction, and construction is applicable to extensive construction simply, easily and fast, and economy is strong.
The technical scheme that purpose of the present invention adopted is its structure: include the cement concrete bottom, be provided with tack coat in the cement concrete bottom surface, making has honeycombed cement surface concrete membrane layer on the tack coat.
The present invention, the cement concrete bottom is cement concrete pavement, square, the sidewalk that forms in advance.
The present invention, tack coat is the waterproof thin layer that the compound by polymer or polymer and filler forms, can with cement concrete bottom and the honeycombed cement surface concrete membrane layer secure bond on it under it.
The present invention, the used honeycombed cement concrete of honeycombed cement surface concrete membrane layer is made up of rubble and sand, cement, the water of gap grading or single grating, every cubic meter of concrete is by weight ratio---cement: rubble: sand: water=150～450kg: 1200～2200kg: 0～500kg: 60～180kg forms the cement concrete that contains hole.
The present invention, the compound of polymer that tack coat is used or polymer and filler, polymer and filler be by weight ratio---polymer: filler=1: 0～15.
The present invention, the used polymer of tack coat is fluoropolymer resin, polymer powder or polymer emulsion.
The present invention, the used filler of tack coat is active filler, as cement, flyash etc., perhaps is inert filler, as calcium carbonate, French chalk, quartz sand etc. or be the mixture that different filler is formed.
The present invention, the polymer that tack coat is used and the compound of filler can add corresponding thinner or water dilutes, also can add corresponding adjuvants, the weight proportion of polymer and thinner or water, auxiliary agent is---polymer: thinner or water: auxiliary agent=1: 0～10: 0～2.
The present invention, construction method step is as follows: foreign material and floating dust on the cleaning cement concrete bottom, by weight polymer and filler being adopted machinery or manually stirring, form the compound of polymer and filler, polymeric material is adopted machinery or manually evenly pave on the cement concrete bottom, form tack coat, then by weight with cement, rubble, sand, hydromining stirs with mechanical or manually even, form the honeycombed cement concrete, adopt the spreading machine or the honeycombed cement concrete that manually paves, utilize spreading machine or manually realize the concrete leveling of honeycombed cement, compacting, after maintenance 1-7 days, form honeycombed cement surface concrete membrane layer, and secure bond is on tack coat.
Overlaying portland cement concrete on the present invention and the cement concrete has very big difference, is embodied in:
(1) honeycombed cement concrete of the present invention is compared with existing common solid cement concrete, its material structure difference, its bonding layer material is also inequality, and is corresponding therewith, and the design of ground surface material match ratio is different, road structure is also different, surface layer is the matrix porosity structural meterials among the present invention, and shrinkage factor is much smaller than common solid cement concrete, the not ad hoc usually tack coat of Portland cement concrete pavement, the road surface early damage is serious, and adhesion strength is much larger than existing road surface binding material among the present invention.
(2) construction technology is obviously different, because the rigid material property of honeycombed cement concrete dry among the present invention, for paving of road surface can adopt asphalt paver or manually pave, leveling, compacting, be different from paving of road surfaces such as existing cement concrete and bituminous concrete, do not need road roller to roll, therefore construction technology of the present invention is simple and convenient, realizes easily, is convenient to promote.
To sum up, the present invention is a kind of new novel road surface structure that is different from existing various road structures.The ground surface material porosity is big, has both had functions such as permeable, noise reduction, and the contraction that is brought by cement simultaneously significantly reduces, road surface bonding layer material adhesion strength height, and road structure is reasonable.
The present invention can guarantee that good road with the thickness that significantly reduces top course under the prerequisite, brings remarkable economical, draws materials conveniently in the road surface, and construction is simple, quick.
