Description
Technical field
The present invention relates to a kind of highway section, waters pavement runoff deep purifying system that water quality is had higher requirements, be specially a kind of pavement runoff purification system.
Background technology
At present, also do not have specialized designs to be used for the system of highway section, waters pavement runoff deep purifying that water quality is had higher requirements, but the deep purifying of these highway section pavement runoffs have very important meaning concerning the protection of local water surrounding.Current, only be confined to preliminary simple process level at the purification of pavement runoff, thereby make the express highway pavement runoff become the potential risk of water environment pollution.Pavement runoff through regular meeting because purify not thorough, the particularly hazardous and noxious substances of some dissolvings degraded pollution that causes local water surrounding to be difficult to repair fully inadequately.The common people's safety and Health brought great influence around it will be given.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can collect and carry out rough purification the express highway pavement runoff, can carry out the pavement runoff purification system that secondary deep purifies by ditching type wetland road pavement runoff again.
In order to solve the problems of the technologies described above, pavement runoff purification system provided by the invention, the pervious asphalt road surface is layered on the waterproof pavement layer, side slope of embankment cobble pervious bed upper end connects the pervious asphalt road surface by water shoot, be equipped with the little permeable transition layer of first rubble above the described side slope of embankment cobble pervious bed, be equipped with the little permeable transition layer of second rubble below, the little permeable transition layer of described second rubble is layered on the impervious clay blanket, be equipped with the plantation soil layer that adds the activated adsorption material on the little permeable transition layer of described first rubble, described side slope of embankment cobble pervious bed is connected with the waterways with permeable cofferdam by second water shoot, described waterways is built by laying bricks or stones by impervious materials, and be connected by the 3rd water shoot with the ditching type wetland, the water side of described ditching type wetland is provided with the 4th water shoot.
The structure of described ditching type wetland be on the cobble pervious bed and below all be covered with the little permeable transition layer of the 3rd rubble, the little permeable transition layer of described the 3rd rubble is provided with wetland filtration and infiltration layer on the upper strata, be provided with vegetation at described wetland filtration and infiltration layer, be provided with header in described cobble pervious bed, described header is connected with described the 4th water shoot.
Be connected with first water shoot between described side slope of embankment cobble pervious bed and the described pervious asphalt road surface.
Adopt the pavement runoff purification system of technique scheme, by utilizing pervious asphalt road surface, waterproof pavement layer, water shoot and permeable kerbstone pavement runoff is collected.The pavement runoff of collecting is carried out rough purification and circulation by the side slope of embankment vegetation, enter the ditching type wetland at last and carry out the secondary deep purification.Ditching type wetland utilization biochemical theory is degraded to remaining noxious pollutant and is discharged by the pavement runoff that is communicated with after the 4th water shoot of header will purify.In the present invention, by the collection of road pavement runoff, thereby prevent its polluted underground water source and it is carried out discharging again behind the deep purifying of permeating the ground.
The present invention is easy and simple to handle, safeguards simply to purify thoroughly, can carry out better protecting to the highway section, waters that water quality has higher requirements, and make it avoid polluting, thereby the common people is to security reference and the irrigation at water source around having ensured.It can guarantee that the motorway water surrounding is not contaminated as far as possible, prevents the chain reaction of ecological damage.Simultaneously, a kind of application of pavement runoff purification system will be improved China's expressway construction project environmental protective measure.
In sum, the present invention can collect and rough purification by the road pavement runoff, can carry out the secondary deep purification by the road pavement runoff again, thereby can satisfy the not contaminated requirement in highway section, waters that water quality is had higher requirements.

Embodiment
In order to make technique means of the present invention, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, Fig. 2 and Fig. 3, pervious asphalt road surface 1 is layered on the waterproof pavement layer 2, waterproof pavement layer 2 is layered on the prevailing roadway layer 14, pervious asphalt road surface 1 is provided with permeable kerbstone 9, side slope of embankment cobble pervious bed 3 upper ends connect pervious asphalt road surface 1 by water shoot 4, be equipped with the little permeable transition layer 6 of first rubble above the side slope of embankment cobble pervious bed 3, be equipped with the little permeable transition layer 22 of second rubble below, the little permeable transition layer 22 of second rubble is layered on the impervious clay blanket 11, be equipped with the plantation soil layer 10 that adds the activated adsorption material on the little permeable transition layer 6 of first rubble, plant on the plantation soil layer 10 and be implanted with vegetation 16, side slope of embankment cobble pervious bed 3 is connected with waterways 5 with permeable cofferdam 12 by second water shoot 17, waterways 5 is built by laying bricks or stones by impervious materials, and be connected by the 3rd water shoot 20 with ditching type wetland 7, the structure of ditching type wetland 7 be on cobble pervious bed 19 and below all be covered with the little permeable transition layer 21 of the 3rd rubble, be provided with wetland filtration and infiltration layer 8 at the little permeable transition layer 21 of the 3rd rubble on upper strata, be provided with vegetation 16 at wetland filtration and infiltration layer 8, in cobble pervious bed 19, be provided with header 23, header 23 is connected with the 4th water shoot 18, is connected with water leg 15 between waterways 5 and the pervious asphalt road surface 1.
