The invention discloses a kind of permeable pavement paving structure of prefabricated foaming concrete lightweight, the permeable pavement paving structure of the prefabricated foaming concrete lightweight includes：Anti-filter geotextiles, are layed on plain soil base；Thin sand, is layed in above the anti-filter geotextiles；Prefabricated permeable foamed concrete, is layed in above the thin sand；The permeable geotextiles of cracking resistance, are layed in above the prefabricated permeable foamed concrete；Big space Asphalt Stabilized Macadam, is layed in above the permeable geotextiles of the cracking resistance；Water-permeating pitch mixed material, is layed in above the big space Asphalt Stabilized Macadam.The present invention possesses the function of permeable, water storage and water purification, and the prefabricated permeable foamed concrete deadweight for being adopted is relatively light, and there is good peptizaiton to load, can ensure the stability after subgrade soils immersion, more extensive than the typically permeable pavement paving structure scope of application.
Description
Technical field
The present invention relates to pavement construction applications, the permeable pavement of more particularly to a kind of prefabricated foaming concrete lightweight is mated formation knot
Structure.
Background technology
City footpath is one of important component part of urban road.It is to pass through that traditional non-permeable footpath is mated formation
Cross flow mode is discharged through rainwater collection well, and footpath is wet and slippery, and hydrops easily make the wet footwear of pedestrian, affect pedestrian's walking safety and
Comfortableness；Lack to urban surface temperature, the regulating power of humidity, exacerbate the tropical island effect in city；Subsoil water is prevented to mend
To path, it is unfavorable for the growth of green plants.
As city pavement mainly undertakes footpound force traffic, requirement for bearing capacity is relatively low relative to car lane, thus is easier
More functional type requirements in addition to traffic is carried are proposed to which.City pavement is contributed for the construction in sponge city in urban road
Play a part of main force during itself strength.
In order to keep the hydrological environment of original soil, it is right to reduce as far as possible during permeable pavement paving structure is laid
The disturbance of original soil, and soil matrix, under water conservation state, its bearing capacity and stability can reduce.At present, traditional permeable pavement
Paving structure is in order to ensure bearing capacity and the stability of soil matrix, or reducing paving structure thickness mitigates deadweight, or to soil matrix
Punished, the former reduces the bearing capacity of paving structure and storage capacity, the latter changes the hydrology ring for keeping original soil
Border.
Content of the invention
For solving above-mentioned technical problem, present invention aim at providing a kind of permeable pavement paving structure, keeping permeable
While function, pavement thickness need not be reduced, and possess enough bearing capacities, without punishing to original soil matrix.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of permeable pavement paving structure of prefabricated foaming concrete lightweight, including following component：Anti-filter geotextiles, are layed in
On plain soil base；Thin sand, is layed in above the anti-filter geotextiles；Prefabricated permeable foamed concrete reservoir bed, is layed in
Above the thin sand；The permeable geotextiles of cracking resistance, are layed in above the prefabricated permeable foamed concrete reservoir bed；Big space
Asphalt Stabilized Crushed Stone Basement, is layed in above the permeable geotextiles of the cracking resistance；Water-permeating pitch mixed material surface layer, is layed in described big
Above the Asphalt Stabilized Crushed Stone Basement of space.
Further, the water-permeating pitch mixed material surface thickness is 4～5cm, and voidage is 15%～20%.
Further, the big space Asphalt Stabilized Crushed Stone Basement thickness is 6～8cm, and voidage is 25%～30%.
Further, the prefabricated permeable foamed concrete voidage is 15%～20%, and thickness degree should be according to engineering institute
Rainfall intensity, the time of the duration of rainfall on ground, the average infiltration coefficient of soil matrix, prefabricated permeable foamed concrete voidage are counted
Calculate.Computing formula is as follows：
In formula, the thickness of the prefabricated permeable foamed concrete layers of H, cm；
I engineerings location rainfall intensity, mm/h；
The infiltration coefficient of f soil matrixs, cm/s；
The t times of the duration of rainfall, min；
The prefabricated permeable foamed concrete voidages of V, %.
Further, the prefabricated foamed concrete interblock gap is filled using fine sand.
Further, the thin sand thickness is 4～5cm.
It is an advantage of the current invention that：The present invention possesses the function of permeable, water storage and water purification, the prefabricated permeable foaming for being adopted
Concrete gravity is lighter, and there is good peptizaiton to load, and the thickness of prefabricated permeable foamed concrete is according to local rainfall
The voidage of the infiltration coefficient of intensity and soil matrix, the time of the duration of rainfall and prefabricated permeable foamed concrete is calculated, and design is more
Adduction is managed, and can ensure the stability after subgrade soils immersion, more extensive than the typically permeable pavement paving structure scope of application.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is further elaborated for below in conjunction with the accompanying drawings with one specific embodiment.
As shown in figure 1, a kind of permeable pavement paving structure of prefabricated foaming concrete lightweight, including：Anti-filter geotextiles 6, paving
Located on plain soil base 7；Thin sand 5, is layed in above the anti-filter geotextiles 6；Prefabricated permeable foamed concrete reservoir bed
4, it is layed in above the thin sand 5；The permeable geotextiles 3 of cracking resistance, are layed in the prefabricated permeable foamed concrete reservoir bed 4
Top；Big space Asphalt Stabilized Crushed Stone Basement 2, is layed in above the permeable geotextiles 3 of the cracking resistance；Water-permeating pitch mixed material surface layer
1, it is layed in above the big space Asphalt Stabilized Crushed Stone Basement 2.The gap of prefabricated permeable foamed concrete reservoir bed 4 is using thin
Sand 8 is filled.
1 thickness of this practical example water-permeating pitch mixed material surface layer is 4cm, and voidage is 18%, and big space Bituminous stabilized is broken
2 thickness of ground mass layer is 8cm, and voidage is 25%, and 5 thickness of thin sand is 5cm, and anti-filter geotextile 6 is using HDPE antiseepage film.
