Abstract
The utility model discloses a kind of pervious concrete paving structures for being suitably applied groundwater level region, it is characterized by comprising pervious concrete layers, metalling is provided with below pervious concrete layer, impermeable layer is provided with below metalling, the impermeable layer is wavy, and impermeable layer is provided with perforated drain pipe at trough.Improved paving structure is due to can effectively avoid rainfall runoff from permeating the ground in water or Groundwater infiltration facility, avoid the risk of polluted underground water with impermeable stratum.
Description
Technical field
The utility model relates to a kind of road paving structure, in particular to it is a kind of be applied to urban road, park, school,
The permeable pavement structure on square.
Background technique
Currently, two kinds of paving structure is widely used in cell road, parking lot etc., one is using closely knit and impermeable
The concrete paving of water, this paving runoff coefficient is big, and when rainfall does not have the stagnant effect for storing rainwater, without volume of regulating and storing, no reduction
The ability of runoff flood peak, rainfall can collect rapidly generation surface runoff in deck surface, to urban drainage pipe network system cause compared with
Big discharge pressure is easy to produce waterlogging risk；Another kind mats formation its surface using pervious concrete paving, and this structure can
A certain amount of rainfall will be absorbed, will be regulated and stored and flood peak clipping ability with certain, but its bottom does not have water-tight structure, rainfall is straight
Access is infiltered into underground water, and there are the risks of polluted underground water resource, in addition, for the phreatic high similar to Shanghai
Area, underground water easily infiltrate into paving structure, this can reduce regulate and store volume and the presence and underground water cross contamination mated formation
Risk.
Utility model content
The technical problems to be solved in the utility model is to solve above-mentioned the deficiencies in the prior art, provides one kind and is suitably applied
The pervious concrete paving structure of groundwater level region.
In order to solve the above-mentioned technical problem, originally practical to adopt the technical scheme that one kind is suitably applied high underground water
The pervious concrete paving structure in position area, it is characterised in that: including pervious concrete layer, be provided with below pervious concrete layer
Metalling, metalling lower section are provided with impermeable layer, and the impermeable layer is wavy, and impermeable layer is provided at trough
Perforated drain pipe.
Further, drainpipe outer peripheral surface is additionally provided with one layer of filter cotton.
Further, the impermeable layer uses waterproof geotextiles.
Further, the coarse crushing stone that metalling includes fine crushing rock layers of the ballast grain sizes less than 15mm and partial size is 20~40mm
Layer, wherein rock layers fine crushing are located above coarse crushing rock layers, fine stone layer height is 150mm, and coarse crushing rock layers are with a thickness of 300mm.
Further, the pervious concrete is three-decker, is followed successively by surface layer, middle layer and base from top to bottom；Table
Layer with a thickness of 1cm-2cm, and internal be equipped with continuous hole；Middle layer with a thickness of 5cm-15cm, voidage 20%-
40%, the aperture of permeable hole is 0.1mm-1.5mm；Base's voidage is 20%-40%, gap aperture in 1-3mm, with a thickness of
15cm。
From above-mentioned technical proposal it can be seen that the utility model has the advantage that improved paving structure due to having
Impermeable stratum, therefore rainfall runoff can effectively be avoided to permeate the ground in water or Groundwater infiltration facility, it avoids impurely
The risk being lauched.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with attached drawing.
As shown in Figure 1, the pervious concrete paving structure for being suitably applied groundwater level region of the utility model, packet
Pervious concrete layer is included, metalling is provided with below pervious concrete layer, is provided with impermeable layer 3 below metalling, it is impermeable
Layer 3 uses waterproof geotextiles.The impermeable layer 3 is wavy, and impermeable layer is provided with perforated drain pipe at trough
1.Perforated drain pipe outer peripheral surface is additionally provided with one layer of filter cotton 2.Filter cotton can prevent the impurity such as sandstone from entering perforation with water flow
Drainpipe, to be blocked.Reverse osmosis permeable layers 3 can use waterproof geotextiles.Improved paving structure is due to having not
Pervious bed, therefore rainfall runoff can effectively be avoided to permeate the ground in water or Groundwater infiltration facility, under avoiding impurely
The risk of water.
Wherein, the coarse crushing rock layers that metalling includes fine crushing rock layers 5 of the ballast grain sizes less than 15mm and partial size is 20~40mm
4, wherein rock layers fine crushing are located above coarse crushing rock layers, fine stone layer height is 150mm, and coarse crushing rock layers are with a thickness of 300mm.
Pervious concrete blocks in order to prevent, takes such as flowering structure, and the pervious concrete is three-decker, from
Surface layer 8, middle layer 7 and base 6 are followed successively by under；Surface layer with a thickness of 1cm-2cm, and internal be equipped with continuous hole；In
Interbed with a thickness of 5cm-15cm, voidage 20%-40%, the aperture of permeable hole is 0.1mm-1.5mm；Base's voidage is
20%-40%, gap aperture is in 1-3mm, with a thickness of 15cm.Variety classes by different porosities and different pore sizes are saturating
Water coagulation soil is layered making permeable concrete ground, and other impurity such as the sandstone, the organic matter that come with water flow are blocked in surface layer,
It allows it to be difficult to enter lower layer, guarantees the unobstructed of pervious concrete internal voids.When surface layer, pervious concrete voidage is reduced to one
When determining degree, it can be rinsed high pressure water flow, the impurity by way of vacuum suction in desurfacing pervious concrete gap, in turn
It keeps pervious concrete voidage relatively constant, guarantees the water permeability of pervious concrete entirety.
Modified paving structure controls effect relative to common water tight concrete structure, with certain runoff volume
Fruit has improvement to the water for failing on-site elimination due to being discharged relatively common waterproof paving runoff there are peak clipping, slow row's effect
The effect of place hydrology performance.The annual catchment occurred in 2016 is counted, relative to the fluid-tight coagulation of tradition
Soil is mated formation, and the structure annual flow overall control rate annual in 2016 is 24.2%, the rainfall which can directly control
Amount is about 5.2mm.To mat formation relative to water tight concrete, structure operation can reduce by 24.2% rainwash for 1 year,
For rainfall be 5.2mm rainfall below, the structure can completely stagnant storage, do not occur to flow out.
