Description
[technical field]
The utility model relates to a kind of paving system, is specifically related to a kind of folder filtrate water-permeable cement concrete sand base brick and mats formation system, belong to drainage works technical field.
[background technology]
Along with the fast development in city, the ratio of the sclerosis such as urban road shared by area is also increasing.These sclerosis place transmission coefficients are very little, and when rainfall, the sclerosis place such as road surface run-off is very large, easily causes waterlogging occurs.
At present, although water-permeable brick is laid on sidewalk in many cities, runoff is seeped into after bottom water-permeable brick, and the pollutant in runoff can be seeped in underground water, polluted underground water.If aqueduct is arranged at bottom, then the rainwater of discharging can pollute receiving water body.In a word, for the pervious surface of mating formation, the pollutant in rainfall runoff is difficult to effectively be removed, and still pollutes the environment.
Therefore, for solving the problems of the technologies described above, the necessary folder filtrate water-permeable cement concrete sand base brick of a kind of advanced person that provides to be mated formation system, to overcome described defect of the prior art.
[summary of the invention]
For solving the problem, the purpose of this utility model is to provide simple, the permeable speed of a kind of structure folder filtrate water-permeable cement concrete sand base brick that is fast, that can strengthen decontamination and improve rainwater utilization to mat formation system.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of folder filtrate water-permeable cement concrete sand base brick is mated formation system, and it comprises sand base water-permeable brick, pervious concrete layer, basic unit, filter material layer, layer of gravel, perforated pipe and rainwater inspection well; Wherein, described sand base water-permeable brick, pervious concrete layer, basic unit, filter material layer, layer of gravel are laid from top to bottom successively; Described perforated pipe is laid in layer of gravel, and it extends into rainwater inspection well; A rain pipe is provided with in described rainwater inspection well.
Folder filtrate water-permeable cement concrete sand base brick of the present utility model system of mating formation is set to further: the thickness of described sand base water-permeable brick is 100mm; The thickness of described pervious concrete layer is 100mm; The thickness of described basic unit is 150mm; The thickness of described filter material layer is 50mm; The thickness of described layer of gravel is 200mm.
Folder filtrate water-permeable cement concrete sand base brick of the present utility model system of mating formation is set to further: the caliber of described perforated pipe is DN100, is embedded in layer of gravel; The diameter of described rainwater inspection well is DN700.
Folder filtrate water-permeable cement concrete sand base brick of the present utility model system of mating formation also is set to: be equipped with greenery patches curb in the side on described sidewalk, opposite side is equipped with road curb.
Compared with prior art, the utility model has following beneficial effect:
1. the permeation rate of sand base water-permeable brick is large, and minimum permeation rate is 5 times of general water-permeable brick speed.
2. by filter material layer, can road rain water be purified, reduce rainwater to the pollution of water body.
3. many pervious layers have water reservation, can reduce municipal Storm Sewer Network design caliber, thus reduce municipal Storm Sewer Network overall cost.
4. work as rainy season set, can effectively avoid city to occur waterlogging, ensure that urban traffic is smooth and easy.
5. this system is conducive to recharge of groundwater and keeps optimum water circulation.
[accompanying drawing explanation]
Fig. 1 is that folder filtrate water-permeable cement concrete sand base brick of the present utility model is mated formation the plan view of system.
Fig. 2 is that folder filtrate water-permeable cement concrete sand base brick of the present utility model is mated formation the sectional drawing of system.
[detailed description of the invention]
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model to be mated formation system for a kind of folder filtrate water-permeable cement concrete sand base brick, and it is made up of a few parts such as sand base water-permeable brick 1, pervious concrete layer 2, basic unit 3, filter material layer 4, layer of gravel 5, perforated pipe 6 and rainwater inspection wells 7.
Wherein, described sand base water-permeable brick 1, pervious concrete layer 2, basic unit 3, filter material layer 4, layer of gravel 5 are laid on sidewalk 8 times from top to bottom successively.Be equipped with greenery patches curb 81 in the side on described sidewalk 8, opposite side is equipped with road curb 82.
Described perforated pipe 6 is laid in layer of gravel 5, and it extends into rainwater inspection well 7, thus rainwater is entered rainwater inspection well 7.
Check in 7 wells in described rainwater and be provided with a rain pipe 9, this rain pipe 9 is for entering city planting ductwork by the Water in Rainwater Drainage in rainwater inspection 7.
Further, described sand base water-permeable brick 1 is suppressed for natural sand and is formed, and water permeability is higher than common water-permeable brick, and intensity is large, thick 100mm, its major function high-moisture-retention, water permeability, the feature of environmental protection, safety, high strength.Mat formation with sand base water-permeable brick, road surface can not ponding under a certain recurrence interval rainfall, even rainy day pedestrian is also not easy to slip, improves vehicle and travel and the safety of pedestrian and comfortableness.And it has loose structure, natural precipitation can rapidly through earth's surface, recharge of groundwater resource.
The thick 100mm of described pervious concrete layer 2, its major function bears weight, and make rainwater fast strikethrough.When rainfall, play a role in filtering.
The described thick 150mm of basic unit 3, its major function is frost heaving resistant, strengthen bearing capacity of foundation soil, rainwater by time have filtration.
The thick 50mm of described filter material layer 4, its major function filters the pollutant removed in runoff, main employing chemisorbed and Physical entrapment.
The thick 200mm of described layer of gravel 5, its major function is as supporting layer.
The caliber DN100 of described perforated pipe 6, is embedded in layer of gravel, and its major function is the rainwater after collecting filtration, enters rainwater inspection well by perforated pipe.
Rainwater inspection well 7 (DN700) on road, can be used as the receiving well of said system, and its major function is the rainwater of conduction from perforated pipe.
Folder filtrate water-permeable cement concrete sand base brick of the present utility model mats formation system when rainy, rainwater can cross fast strikethrough sand base water-permeable brick 1, again successively by pervious concrete layer 2, basic unit 3, filter material layer 4, layer of gravel 5, every layer all has certain filtration, purification effect, can effective purifying rainwater water quality.Filter material layer 4 relies on its chemistry and physical action, removes the most of pollutant in runoff.Perforated pipe 6, by the rainwater-collecting after filtration, purification, is transported to rainwater inspection well 7, and unnecessary rainwater is discharged to downstream water by rainwater inspection well 7.When amount of precipitation is very large, a part of rainwater can be stored in sand base water-permeable brick 1, pervious concrete layer 2, basic unit 3, filter material layer 4, and in layer of gravel 5, and in perforated pipe 6, part rainwater just can form surface flow at road surface.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
