Description
Technical field
The present invention relates to sponge city urban pavement engineering field, more particularly to a kind of heavy grade road permeable pavement is slow oozes
Structure and its construction method.
Background technology
In recent years, country advocates the construction in " sponge city " energetically.Sponge city refer to city can as sponge,
Adapt to environmental change and tackle natural calamity etc. with good " elasticity ", water suction, water storage, infiltration, water purification when raining, need
By the water stored " release " and it is used when wanting.Sponge city can effectively alleviate urban waterlogging, prevent that level of ground water from declining
Harm.
Porous pavement is a kind of road surface load-carrying members that can pass through water.Permeable pavement has following two functions：Water seepage function,
Rainfall runoff is permeated in lower soil；Peak clipping function, can interim water storage, treat that rainwater is discharged into draining by peak runoff later
System.In the prior art, permeable pavement structure generally comprises the coarse sand screed-coat above native soil and permeable surface layer, existing
The terrain slope requirement of water paving structure is less than 3%, 5% is most very much not should be greater than, to ensure that the subregion of permeable pavement will not
Bear too high hydraulic pressure.
And many regional physical features gradients is larger, especially heavy grade road of the terrain slope requirement more than 5%, rainwater is along slope
Degree is rapid to flow down, and it is non-perpendicular under ooze, reduce the overall infiltration rainfall in permeable pavement region, the infiltration effect of permeable pavement is big
Give a discount.
Thus, the present inventor relies on experience and the practice for being engaged in relevant industries for many years, proposes that a kind of heavy grade road is permeable
Mat formation it is slow ooze structure and its construction method, the defects of to overcome prior art.
The content of the invention
Delay it is an object of the invention to provide a kind of heavy grade road permeable pavement and ooze structure and its construction method, overcome existing
Have rainwater present in technology along the gradient flow down too fast, infiltration effect difference the problem of, this is slow to ooze structure and can retain and infiltrate rainwater and keep away
Exempting from it, downstream lower is collected too quickly, strengthens store function, promotes rainwater diafiltration, it is ensured that permeable pavement can play on a large scale
Effect.
The object of the present invention is achieved like this, and a kind of heavy grade road permeable pavement is slow to ooze structure；The heavy grade road
Road permeable pavement is slow to be oozed structure and mats formation along road grade in native soil, and gravel aquifer, the gravel are laid in the native soil
Coarse sand screed-coat is laid on stone aquifer, permeable pavement surface layer is laid on the coarse sand screed-coat, between the gravel aquifer is interior
It is multiple in the waterproof baffle being vertically arranged every being provided with.
In the better embodiment of the present invention, the bottom of each waterproof baffle, which is fixed, is inserted in the native soil
It is interior, the top of the gravel aquifer is extended down on the top of each waterproof baffle.
In the better embodiment of the present invention, the two neighboring waterproof baffle is along the spacing on horizontal length direction
For 5~10m.
In the better embodiment of the present invention, the width dimensions of each waterproof baffle are more than the permeable pavement face
The width dimensions of layer.
In the better embodiment of the present invention, the waterproof baffle is concrete baffle plate or resin baffle plate.
The purpose of the present invention can also be achieved in that a kind of heavy grade road permeable pavement delays the construction method for oozing structure,
The construction method includes：
The native soil in step a, smooth region to be mated formation；
