(2)The construction of sand-gravel cushion:Complete step(1)Afterwards filling material is carried out using excavator, dump truck is by aggregate transporting To where carrying out after base treatment, paved with bull-dozer, pressed with road roller again after finally being flattened with land leveller It is real;
(3)The making of pervious concrete:Complete step(1)、(2)The same of basic water permeable concrete and surface layer pervious concrete is carried out afterwards When pave, wherein basic water permeable concrete is first by manually slightly being shakeout, then vibrated with plate vibrator, it is prepared by surface layer pervious concrete Then middle elder generation is ensureing to be paved with rubbing machine in the state of continuous filler by manually slightly shakeouing pervious concrete, spreads out Paving number of times is no less than 3 times, rubbing machine and receives face machine and need to synchronously carry out with the compacting that paves in this step;
(4)Road surface joint-cutting, joint filling:Complete step(3)Afterwards road pavement is conserved, and 7 days road pavements of maintenance carry out joint-cutting, fill out Seam, using gap filler expansion joint is filled;
(5)The spraying of sealer:After completion of the above steps the surface of pervious concrete is cleaned using jetting machine, Spraying sealer can be carried out after dry tack free 24h, current can be used after pervious concrete intensity meets the requirements.
Its feature further is as follows:
Pave height of the described basic water permeable concrete when paving paves height 10mm higher than design.
Described gap filler is polyurethane low modulus caulked joint ointment or thiorubber. class caulking compounds.
Described expansion joint requires:Contracting kerf spacing≤6m, stitches wide 5~8mm, and seam is deep not less than the 1/3 of Concrete Thick, expansion joint (E.J.) Spacing≤18m, stitches wide 15~20mm.
The making step of described pervious concrete needs to be stirred pervious concrete before carrying out, and described stirring is Rubble and liquid adjuvants are placed in blender and are stirred in advance, cement, Booster are added after surface of material is moistened, is stablized Agent and dispersant, the workability for stirring one minute backsight mixture suitably adds water, till mixture reaches requirement.
Due to the utilization of above-mentioned technical proposal, the present invention has compared with prior art following beneficial effect:
1st, high-bearing capacity.Globality high-mechanic pervious surface pavement system, its resistance to settling can be better than general permeable brick flooring system System, while this pavement system also has the ability that opposing soil freezing heave produces destruction to rigid pavement;
