Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use such as " upper and lower, top, bottom " typically refers to the direction as shown in Figure of description.
The utility model provides a kind of head water permeable pavement, the higher pervious layer of water permeability can be formed to the framework of water guide in subterranean layer, and in conjunction with the macadam gradating layer that its underpart is equipped with, make ground surface ponding can import underground fast, moisture is drawn by the macadam of bottom and soil, thus make the Soil and air under water permeable pavement, aqueous phase fully contacts, form the underground wetlands ecosystems that microorganism is active, part ponding also can upwards evaporate for naturally reducing environment temperature, suppress urban heat island to reduce air-conditioning power consumption, environmental protection simultaneously.
Refer to Fig. 1, percolating water paving structure of the present utility model, comprise successively under upper: pervious layer 100, macadam gradating layer 200 (i.e. rubble also can serve as reservoir bed), grading of soil layer 300 (i.e. soil horizon).Particularly, this percolating water paving structure is arranged on the soil horizon 300 on ground, this soil horizon 300 sets gradually from top to bottom: pervious layer 100, macadam 200, in the macadam 200 that this water conservation layer 400 is arranged on pervious layer less than 100 or soil horizon 300, or in both interlayers.
Please also refer to Fig. 2, water conservation layer 400 comprises water conservation layer matrix and some water storage parts be arranged on alternate form in this water conservation layer matrix.The moisture on water permeable pavement top layer is dredged in water conservation layer 400 by above-mentioned pervious layer 100, and portion of water is stored in water conservation layer matrix and these water storage parts, and then also can filter moisture; Moisture in water conservation layer matrix can continue by space wherein to enter in the soil horizon 300 of its underpart, slowly permeable subterranean soil horizon 300, activating soil, or enters in the reservoir of underground setting.
Particularly, when being arranged in macadam by this water conservation layer 400, water conservation layer matrix of the present utility model is then rubble; Water storage parts are water storage ball 80, and please also refer to Fig. 3, water storage ball 80 adopts the PP material of high-quality to make, quality is light, and toughness is comparatively strong, has good crushing resistance, guaranteeing that it is arranged in rubble can not be damaged because of extruding, and certainly, water storage ball also can be made via other metals or non-metallic material.Water storage ball 80 offers multiple water through permeable hole 81, and wherein uniformly in the border of water storage ball 80 can arrange permeable hole 81, this permeable hole 81 not only can be used for moisture to pass through, and upwards can also discharge for the humid air in soil horizon 300 and macadam 200.And every square metre arranges at least ten pieces of described water storage balls 80 in water conservation layer matrix, the porosity that both can effectively increase between rubble does not affect the structural strength of macadam simultaneously.Then when moisture enters after in water conservation layer 400, temporarily can be stored in the gap of rubble formation, and water storage ball 80 can be entered into by this permeable hole 81, to store.
Due to the storing water performance of water storage ball 80 itself, the permeable amount of whole water permeable pavement can be made to increase, rainwater can be stored rapidly, effectively alleviate the pressure that instantaneous concentrated rainfall causes water permeable pavement; Avoid because the gap of macadam 200 itself is less, can water-holding quantity limited.And water storage ball 80 is because its hollow is arranged, not only can short time a large amount of water, can also all penetrate into after in the soil horizon 300 of below by the moisture in macadam 200, the moisture of its storage inside is sucked out successively, profit is carried out to soil, to prevent in pavement structure in the past soil horizon 300 because can not supply in time after water loss, cause soil easily to harden, alkalize, therefore can impact the ecological environment of underground.
And in the past in order to make water permeable pavement have good water permeability, the porosity of macadam 200 need be ensured, macadam 200 often selects ballast grain sizes to be 3 ~ 5cm, but because the rubble of this particle diameter need carry out multiple times of filtration screening, while adding cost of production, because particle diameter can impact the planeness of other surface layers be laid on macadam 300 comparatively greatly undoubtedly.And after water conservation layer 400 is set, it effectively can increase the porosity between water conservation layer 400 medium stone material (i.e. macadam 200) by the mode that interval in crushed stone material arranges water storage ball 80, and the diameter of water storage ball 80 is preferably set to 1/4 to 1/5 of water conservation layer 400 thickness, while keeping porosity, ensure that to make water storage ball 80 the paving planeness of macadam 200 is not affected.Therefore when water storage ball 80 ensures that porosity is low, select the crushed stone material of 1 ~ 3cm particle diameter can ensure larger water yield, effectively can reduce the choice requirement for macadam 200 medium stone material, and because ballast grain sizes elects 1 ~ 3cm as by disposable screening, greatly reduce cost.
The shape of certain the utility model to water storage parts does not limit, in other embodiments, water storage parts can also be the block structure of hollow, or the hollow containment structures of other shapes, as long as may be used for water storage and can increase the space between crushed stone material in crushed stone material.And if when this water conservation layer 400 is arranged in soil horizon 300, this water conservation layer matrix is then soil, and can, at described water storage parts outer setting filtration, avoid impurity gravel to enter in these water storage parts.
Further, also absorbent material is provided with in above-mentioned water storage parts, this absorbent material can increase the moisture storage capacity of water storage parts, the moisture president of its inside stays for a long time and deposits, after the moisture in water conservation layer 400 rubble gap is dredged out gradually, water storage parts are because have absorbent material, and the moisture of its absorbed inside can slowly be sucked out, while increasing the storage capacity of water storage parts, in the further long period, avoid soil plate.
Further, discharge structure 90 is also provided with in described water conservation layer 400, this discharge structure 90 is gutter, band drain or pottery gravel, can also relative set guiding gutter or aqueduct below this discharge structure 90, the moisture dredged by discharge structure 90 is pooled to reservoir or other can concentrate water part.And can adopt stage manner that canvas cloth is set below above-mentioned discharge structure 90, running into when raining heavyly to make water permeable pavement, the moisture of a part infiltrates in soil horizon 300 by spacer rapidly, another part moisture by the throttling of canvas cloth section, and is collected in reservoir or other water collecting equipments by discharge structure 90.Certainly nonwoven layer or glass layer can also being adopted as filtration beds above above-mentioned discharge structure 90, to filter the water source collected, preparing for again utilizing.
As shown in Figure 4, particularly, pervious layer 100 is formed by the condensation of concrete perfusion in permeable support B above-mentioned pervious layer 100, because permeable framework B is combined with concrete, permeable support B can serve as the load-bearing pedestal in paving, effectively can solve road surface load-bearing problem, increases the application life in paving.Permeable support B is when making percolating water paving structure simultaneously, can form multiple permeable hole and air-vent on top layer, paving, and then pervious layer 100 has the effect that the humid air of moisture on the ground and underground is circulated mutually concurrently.
