Permeable floor has the following characteristics: a high permeability permeable floor has a 15% -25% porosity, permeability enables speeds of up to 31-52 l / m / h, much higher than most effective rainfall in discharge rate of the best drainage configurations. Second, high bearing capacity identified by the national testing agencies, permeable bearing capacity of the floor is completely able to achieve the standard C20-C25 carrying concrete, higher than the carrying capacity generally permeable brick. Three, good decorative effect permeable floor with matching color optimization solutions can meet the unique and creative designers to achieve the required different environments and personalized decor. It is generally difficult to achieve permeable brick. Fourth, ease of maintenance feared pore blockage problem is not necessary to make it unique permeable paving system simply by way of the high-pressure washing can be easily resolved. Five, freeze-thaw resistance permeable pavement has more capacity than the freeze-thaw resistance of concrete pavement is generally not affected by the freeze-thaw fracture surface, because it has a larger pore structure itself. Six, durability, wear resistance permeable flooring durable than asphalt, close to ordinary floor, avoiding the general presence of permeable brick short useful life, not economic and other shortcomings. Seven high heat density of the material itself is low (15-25% of voids) to reduce the heat storage capacity, the unique pore structure makes the lower surface of the ground to reduce the temperature of the incoming temperature of the pavement surface, these features permeable paving system so close to natural vegetation cover on the ground and in the endothermic heat storage function. Its widely used in municipal trails, garden paths, Town Square, the upscale residential district, parking, business office, outdoor sports (badminton stadium, basketball stadium, etc.). Its scope of application of municipal trails, garden paths, Town Square, the upscale residential district, parking, business office, outdoor sports (badminton stadium, basketball stadium, etc.). Permeable floor (1) Ground leveling: strict check elevation, flat test case basis. After the foundation of the flat rolling compaction, quality sampling and testing ground compaction ring knife, dense coefficient ≥0.93; (2) Cushion: construction plans in accordance with the requirements laid graded gravel or sand and gravel cushion, with the required thickness load requirements vary, depending on the thickness by mechanical or rolling compaction equipment, compaction factor according to design requirements; (3) laying sand filter layer: 3mm thick laying on the cushion, the coarse filter layer leveling, regular watering and roller or rolling vibration compacting plate vibrators; (4) support templates: graphic design requirements according to elevation and support provided template, shall ensure that the requirements and design pattern lines strength requirements, and the elevation of the upper edge of the template with the floor surface to be permeable to the top surface elevation consistent; (5) Default expansion joints: When permeable floor length was longer than the time 6m or construction phase at the surface and other materials should be pre-swelling material (below the paste on the design elevation 55mm wide at 5mmn thick 5Ommn foam strips); (6) in strict accordance with the intensity of mixing and matching design requirements permeable floor. Additives and pigments applied electronics, stirring time control 3mmn appropriate); (7) pouring permeable floor: concrete pavers or flat vibrators vibrating compaction. Pouring surface must be synchronized with the primary. Intervals not more than two hours, and the grass during the interval should be covered in concrete water retention. Friction surface layer of concrete leveling machine vibrated dense vibration, large pore area with artificial leveling compaction. After the completion of the first pouring specimens should be color contrast, can continue construction after passing. Because of dry concrete, should be undertaken at night, to avoid moisture loss greater; (8) explicit material surface pretreatment: face layer is permeable floor explicit material, you should use a surface treatment agent at the end of the paving within half an hour to do the pre- treatment, then film conservation. 6-8 hours (determined in accordance with the conservation of temperature and humidity, and other factors) do surface processing, to achieve the effect of sexually explicit material, and then continue curing coating pretreatment; (9) film, conservation: the completion of the rear surface layer of concrete paving should be covered membrane combined with water conservation. Maintenance should be carried out after the concrete forming 3Ommn, curing time should be for seven days. (10) Cleaning Seal: For color permeable floor should be sealed. Surface layer of concrete curing 7 days wash with clean water until the surface completely dry, the double c polyurethane sealant evenly sprayed on the surface to protect the face, stand for 8 hours (the length of time can be adjusted according to the scene temperature, ventilation, etc.) For explicit material permeable floor, when the design requirements do not spray without the seal.
