Abstract
The utility model discloses a kind of draining double filtering type road surface, including asphalt concrete layer, the first non-fine concrete filter layer, sub-surface and the second non-fine concrete filter layer, the asphalt concrete layer, the first non-fine concrete filter layer, sub-surface and the second non-fine concrete filter layer are laid on the ground from top to bottom successively, the bituminous concrete layer porosity is not less than 22%, the sub-surface includes super absorbent resin layer and water storage crushed rock base course, and the super absorbent resin layer is laid on water storage crushed rock base course upper end.The draining double filtering type road surface uses the design of rubble water storage basic unit and super absorbent resin layer, once rainfall, super absorbent resin layer can quickly absorb water body of 200 times more than own vol, prevent that precipitation leakage is excessive, damage roadbed, have the function of water storage concurrently simultaneously, can slowly discharge moisture for a long time, the water discharged can both permeate recharge of groundwater source downwards.
Description
【Technical field】
Brick or concrete duct field is the utility model is related to, more particularly to a kind of draining double filtering type road surface.
【Background technology】
With the fast development of social economy, people's trip quality requirement constantly upgrades, and means of transportation are also further convex
The theory of aobvious " environment-friendly ".In field of road, how to improve the performance of road, to society provide safety, it is comfortable,
The road of environmental protection, has become urgent problem under the new period
At present, urban surface is gradually covered by impervious blanket.But this pavement structure be present, such as city
City's underground water cannot supplement, and surface water can not compromise the water balance in city by being oozed under pavement structure；Due to surface compact
Pavement structure the rainy day can not timely draining, while inside pavement structure lack water storage design, exacerbate urban waterlogging calamity
Evil；Prevailing roadway structure need to set up current collection device in road both sides, somewhat expensive and quantities is huge；Deposited in Urban Rain
In substantial amounts of pollutant, pavement structure lacks filter layer, easily causes formation contaminant, therefore, a kind of it is proposed that draining double filtering type
Road surface.
【Utility model content】
Main purpose of the present utility model is to provide a kind of draining double filtering type road surface can solve problem above.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of draining double filtering type road surface, including asphalt concrete layer, the first non-fine concrete filter layer, sub-surface and
Two non-fine concrete filter layers, the asphalt concrete layer, the first non-fine concrete filter layer, sub-surface and second mix without sand
Coagulate native filter layer to lay from top to bottom successively on the ground, the bituminous concrete layer porosity is not less than 22%, the road surface
Basic unit includes super absorbent resin layer and water storage crushed rock base course, and the super absorbent resin layer is laid on water storage crushed rock base course
End.
Further, the asphalt concrete layer is made up of open-shelf range OGFC asphalt concrete materials.
Further, the first non-fine concrete filter layer and the second non-fine concrete filter layer are by strength grade
More than 42.5 Portland cements and coarse aggregate are made.
Further, the asphalt concrete layer thickness is 5-8cm, and the first non-fine concrete filter layer thickness is 2-
3cm, the super absorbent resin thickness degree are 3-5cm, and the water storage crushed rock base course thickness is 50-70cm, and described second without sand
Concrete filter layer thickness is 3-5cm.
Compared with prior art, the utility model has the advantages that：Stored up using rubble on the draining double filtering type road surface
The design of water-base and super absorbent resin layer, once rainfall, super absorbent resin layer can be quickly absorbed more than own vol
200 times of water body, prevent that precipitation leakage is excessive, damage roadbed, while have the function of water storage concurrently, can be in slowly release for a long time
Moisture, the water discharged can both permeate recharge of groundwater source downwards, and using twice non-fine concrete filter layer, first mixes without sand
Coagulate native filter layer to be arranged on below asphalt concrete layer, be advantageous to supplement the effect of pavement strength, improve road surface bearing capacity and
Surface layer rutting resistance, the second non-fine concrete filter layer are arranged between ground and sub-surface, prevent soil particle from passing through pump
Suction effect enters basic unit, strengthens roadbed supporting effect.
【Brief description of the drawings】
Fig. 1 is the utility model overall structure diagram.
In figure：1st, asphalt concrete layer；2nd, the first non-fine concrete filter layer；3rd, sub-surface；4th, second without sand coagulation
Native filter layer；5th, super absorbent resin layer；6th, water storage crushed rock base course.
【Embodiment】
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in figure 1, a kind of draining double filtering type road surface, including asphalt concrete layer 1, the first non-fine concrete filter layer 2,
The non-fine concrete filter layer 4 of sub-surface 3 and second, the asphalt concrete layer 1, the first non-fine concrete filter layer 2, road surface
The non-fine concrete filter layer 4 of basic unit 3 and second is laid on the ground from top to bottom successively, the porosity of asphalt concrete layer 1
Not less than 22%, the sub-surface 3 includes super absorbent resin layer 5 and water storage crushed rock base course 6, the super absorbent resin layer
5 are laid on the upper end of water storage crushed rock base course 6.
Wherein, the asphalt concrete layer 1 is made up of open-shelf range OGFC asphalt concrete materials.
Wherein, the first non-fine concrete filter layer 2 and the second non-fine concrete filter layer 4 are by strength grade 42.5
Above Portland cement and coarse aggregate are made.
Wherein, the thickness of asphalt concrete layer 1 is 5-8cm, and the thickness of the first non-fine concrete filter layer 2 is 2-
3cm, the thickness of super absorbent resin layer 5 are 3-5cm, and the thickness of water storage crushed rock base course 6 is 50-70cm, second nothing
The thickness of sand concrete filter layer 4 is 3-5cm.
Beneficial effect：Construction is simple, cost-effective, new draining double filtering type pavement structure and the construction on plain asphalt road surface
