The preparation method of described pervious concrete, comprises the following steps:
(a), by the cement of half weight, water, nemalite, carbamate and polycarboxylic acids dehydragent stirring mix which Uniformly, 90-120 DEG C of whipping temp;
(b), by basalt fibre, iron sesquioxide, melamine resin add step(1)In the blending ingredients for obtaining, stirring makes which Mix homogeneously, 80-100 DEG C of whipping temp, stirring pressure are 1.5-2 atmospheric pressure;
(c)The cement of half weight, acrylate, Lauxite are added into step(2)In the blending ingredients for obtaining, stirring makes which Mix homogeneously, 100-120 DEG C of whipping temp, stirring pressure are 1-1.5 atmospheric pressure, make pervious concrete;
(2)Personnel prepare:Pervious concrete pavement construction teams and groups are set up, construction teams and groups personnel must make special through professional Technical training, and carry out the training record of correlation;
(3)Farm Planning:Placing of material place, stirring place and warehouse and fire fighting device arrangement are carried out, placing of material meets stirs Mix the requirement of type;Job site should be equipped with rain-proof, moistureproof placing of material place, and material should be stacked by mark respectively, handling and Must not arbitrarily throwing during carrying;
(4)Operating condition:Before pervious concrete surface construction, make cleaning treatment to basic unit, the substrate surface after process should be thick It is rough, without hydrops, and keep moisture state;
(Two)Surveying and locating:Required according to Pavement Design, the width on road surface, absolute altitude and drainage grade are surveyed and is set, carry out labelling;
(Three)Formwork:Kerbstone is installed as template, after the completion of unwrapping wire, edge stone foundation trench is excavated, excavation width is than edge ground mass Plinth width 100mm, lays 100mm thickness C15 concrete cushions, is encapsulated with C20 pea gravel concretens on the outside of kerbstone, and kerbstone is installed Cheng Hou, the height, steadiness to kerbstone inspected for acceptance comprehensively it is qualified after carry out pervious concrete construction;
(Four)Pave, be compacted:Underlayment is first poured according to design requirement, 3d cast surface layers are treated, the coefficient of loose laying that paves is controlled 1.1 After mix paves, first mix is spread out with floating rule push away it is even it is levelling after, with low frequency vibrator vibration drag flat, time of vibration control In 1min, prevent excessively closely knit, affect permeable effect, it is after pervious concrete compacting, mixed to water penetration using flat board polishing machinery Solidifying soil surface layer carries out receipts face, accomplish big face it is smooth, uniform, without pit-hole, be allowed to the good uniformity and degree of compaction;
(Five)Maintenance:Moisture-keeping maintaining is carried out to pouring covering colour bar cloth cooling after the pervious concrete face 30min for completing, during maintenance Between 7-14d, water drenching number of times should make concrete surface keep moistening;
(Six)Expansion joint cutting, the cementation of fissures:Road surface pours and completes the laggard walking along the street face partition seam cuttings of 24h, contracting seam width 10mm, depth 50mm, the cutting process after the completion of concrete speading, movement joint are arranged and little expansion joint (E.J.) together are set per 5m, stitch wide 10 ~ 15mm;Work as construction When length is more than 30m, if width is the expansion joint of 10 ~ 15mm;In construction, construction joint can replace expansion joint;
(Seven)Brushing surface layer protective agent:After pervious concrete surface construction, the paint surfaces protective agent in 7 days;Sprayed surface is protected Before shield agent, surface layer should be cleaned.
Beneficial effects of the present invention:
First, economic benefit
1 installation cost is low:Pervious concrete has low installation cost.In the case where this concrete road surface is installed, just it is fitted without down Necessity of water channel and underground piping.This specific mounting cost is lower than the cost in traditional gutter and draining pipeline.
2 improve land utilization ratio:As he can keep rainwater, you need not buy extra soil to install large-scale pond With other filtration systems, to keep rainwater.
3 low life cycle costs:This is the material of a sustainable development, and the life-span is higher than in normal concrete.If built It is good that the parking lot made is safeguarded, most area may continue 20 to four ten years.
2nd, social benefit
1 concrete road surface-A water penetrations, can comparatively fast eliminate the hydrops in road, parking lot when rainy;Can mitigate when rainfall is concentrated The burden of municipal drainage facility, prevents river inundation and water pollution.
2 prevent surface gathered water, and night is non-reflective, increase road surface safety and current comfortableness.
3rd, environmental protection aspect
1 pervious concrete pavement has water penetration, and rainwater can be made to rapidly permeate into underground, subsoil water is reduced, and keeps soil moisture, dimension The ecological balance of shield subsoil water and soil, to be avoided that again and cause setting of ground because of exhaustive exploitation subsoil water.
The porosity of 2 concrete systems is larger, with sound absorption, can reduce environment noise.
Urban pollutant can be adsorbed in 3 substantial amounts of spaces(Such as dust), reduce dust pollution.And ease for maintenance, only need to be with height The method of pressure washing, you can process hole blockage problem.
