The plastic grid sand base water-permeable brick of the present utility model system of mating formation is further: described permeable surface thickness is 29-34cm, and graded broken stone layer thickness is 25-45cm.
The plastic grid sand base water-permeable brick of the present utility model system of mating formation is further: in the middle of described graded broken stone layer and soil matrix layer, lay Unidirectional water permeable geotechnique layer of cloth.
The plastic grid sand base water-permeable brick of the present utility model system of mating formation is further: in described permeable surface layer, comprise four water-permeable bricks that 2*2 arranges.
The plastic grid sand base water-permeable brick of the present utility model system of mating formation is further: in described permeable surface layer, comprise four side by side or the water-permeable brick of horizontally-arranged.
The plastic grid sand base water-permeable brick of the present utility model system of mating formation is further: the water-permeable brick that comprises eight horizontally-arrangeds or tandem in described permeable surface layer.
The plastic grid sand base water-permeable brick of the present utility model system of mating formation also can be: the water-permeable brick that comprises 16 tandems in described permeable surface layer.
Compared with prior art, the utlity model has following beneficial effect: the plastic grid sand base water-permeable brick of the present utility model system of mating formation has higher intensity, improve the speed of rainwater infiltration, keep the change flat bed, speed of application is fast, realize modular construction, surface layer is very smooth, very attractive in appearance after mating formation, and uses regenerated plastics, energy-saving material-saving, environmental protection is ecological again.

[detailed description of the invention]
Refer to Figure of description 1 to shown in Fig. 7-2, the utility model is a kind of plastic grid sand base water-permeable brick system of mating formation, and it is made up of several parts such as the soil matrix layer 1 of laying from bottom to top, graded broken stone layer 2 and permeable surface layers 3.
Wherein, the compacted density of described soil matrix layer 1 is not less than 93%, and land-based construction is carried out DBJ01-45.
Described graded broken stone layer 2 thickness are 25-45cm.In the middle of described graded broken stone layer 2 and soil matrix layer 1, lay Unidirectional water permeable geotechnique layer of cloth 4.
Described permeable surface layer 3 thickness are 29-34cm, and it comprises plastic grid 5, ovum macadam 6 and water-permeable brick 7.The material of described plastic grid 5 is regenerated plastics, and waste plastics is turned waste into wealth, and modularization is manufactured and formed, and meets energy-saving material-saving theory.In this plastic grid 5, be provided with support bar 8.Described ovum macadam 6 is laid in plastic grid 5, and is positioned at the below of support bar 8.The ovum rubble of ovum macadam 6 adopts the single grating that particle diameter is 5mm-10mm, and maximum particle diameter is no more than 15mm.Described water-permeable brick 7 is supported in the top of support bar 8, and concordant with the end face of plastic grid 5.
Further, described permeable surface layer 3 can adopt six kinds of forms, comprise four water-permeable bricks that 2*2 arranges, four side by side or the water-permeable brick of horizontally-arranged, eight horizontally-arrangeds or the water-permeable brick of tandem, the water-permeable brick of 16 tandems, also the spread pattern of self-defined plastic grid and water-permeable brick as required.
Plastic grid sand base water-permeable brick of the present utility model is mated formation system in the time mating formation, can be according to the width length in road or place, size, selects the specification size that adopts plastic grid, can adopt the grid of disparate modules to carry out composite assembly, use meets design requirement.Because of its specific plastics material mesh structures, in actual pavement construction, porous base course adopts the construction of grouting formula, can make the firm performance of basic unit stronger.Constructor can effectively ignore the construction of leveling layer, accelerating construction progress, and after construction, plastic grid surface and sand base brick can keep same plane, and very smooth, visual effect is fine.In the time of rainfall, the runoff on earth's surface can be penetrated into underground by sand base brick soon, under certain amount of precipitation, ground can not produce ponding, underground cobble stores physical efficiency and stores a large amount of rainwater, outer row's rainwater flow of control band, flood peak clipping, reduces the generation of region waterlogging, be seeped into the broken rainwater of grating simultaneously and can continue to be seeped in underground, thereby can recharge of groundwater.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, any amendment of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
