Description
Technical field
The utility model relates to permeable pavement structure field, especially relates to a kind of permeable pavement structure with square water purification basic unit.
Background technology
In recent years, waterlogging problem occurs again and again, and for addressing this problem, the plan of setting up rainfall pumping station has all been made in many cities.Setting up of rainfall pumping station can effectively solve waterlogging problem undoubtedly, but this also means and will greatly increase the demand of resource energy consumption.For reaching object that is green, energy-saving and environmental protection, these new ideas that country proposes " sponge city ", in the concept in " sponge city ", the laying on " permeable road surface " is one of them emphasis, broken people traditional cities is built in this understanding of hard surface everywhere.Meanwhile, city first flush rainwater has with serious pollution feature, heavy rain period, and municipal sewage plant's throwing-on of pipe network end, can bring the problems such as the energy consumption of Wastewater Treatment Plant increases, treatment effect is undesirable.Therefore, develop a kind of stable road structure tool having permeability and rainwater preprocessing function concurrently to be of great significance.
Chinese patent CN103669167A discloses a kind of permeable pavement structure, permeable pavement structure comprise successively from top to bottom by longitudinal tile arrange the ground formed catchment layer, the filter layer be made up of dank material, in establish the rainwater-collecting layer of weeper drain, and bed course and original subgrade layer, wherein, filter layer also comprises the leveling layer on upper strata and the basic unit of lower floor.This patent is the invention proposed for porous pavement surface layer structure, can only permeate rainwater and collect, but the application is the invention proposed for porous pavement basic unit, not only starting point is different, and the application is while carrying out rain penetration and collection, preliminary purification can also be carried out to rainwater.
Utility model content
The purpose of this utility model is exactly provide a kind of permeable pavement structure having the square water purification basic unit of band of permeability and rainwater preprocessing function concurrently to overcome defect that above-mentioned prior art exists, reaches green, energy-conservation object.
The purpose of this utility model can be achieved through the following technical solutions:
With a permeable pavement structure for square water purification basic unit, be arranged on roadbed, be made up of the permeable surface layer set gradually from top to bottom, square water purification basic unit, bed course,
Described square water purification basic unit is made up of the reinforced concrete frame and the square water purification structure be filled in framework being separated into square structure.
The bottom even perforate of described reinforced concrete frame.
Described perforate is highly the 1/16-1/20 place of reinforced concrete frame height.
Described square water purification structure is made up of top void layer, filtration beds and the supporting layer set gradually from top to bottom.
The aspect ratio of described top void layer, filtration beds and supporting layer is 1:6-7:1.
Described filtration beds by particle diameter 0.9 ~ 1.2mm, density 2.50 ~ 2.70g/cm
3, the quartz sand of K80<1.4 is formed.
Described supporting layer is made up of the heavy mineral of particle diameter 4 ~ 8mm.
Also waterproofing course is provided with between described square water purification basic unit and bed course.
Compared with prior art, the utility model has the following advantages:
One, the water purification structure of this permeable pavement structure is square, can carry out tiling and producing in batches, for the engineer applied of this structure provides the foundation.
Two, this permeable pavement structure water purification structure is square, compares water purification structure and reinforced concrete frame area is all placed in the middle with band rhombus with the permeable pavement structure of hexagonal water purification basic unit.Therefore, its water purification penetrating power and intensity and toughness are all in position, middle reaches.Being applicable to penetrating power and intensity and toughness requirement is not very high road structure.
Three, this permeable pavement structure adopts steel concrete square frame as basic unit's load part, stressed clear and definite, power transmission is direct.In square box central filler water purification structure, make porous pavement can also play the effect of preliminary water purification while can stablizing power transmission.
Four, this permeable pavement structure can also improve the rain-water accumulating outlet capacity in whole city, evacuates heavy rain precipitation from source.
