Detailed description of the invention

The present invention is described in further detail below in conjunction with the accompanying drawings, to make art technology Personnel can implement according to this with reference to description word.

As it can be seen, the open a kind of ecological permeable road surface of the present invention, including: permeable surface layer 1, Plain color pervious concrete basic unit 2, blotter 3；Described permeable surface layer 1, plain color are permeable mixed Solidifying soil matrix layer 2, blotter 3 are sequentially distributed from top to bottom, described plain color pervious concrete Basic unit 2, blotter 3 are provided with several for permeable permeable hole, described permeable Hole is vertically arranged, and it is permeable mixed that described permeable hole sequentially passes through permeable surface layer, plain color from top to bottom Solidifying soil matrix layer also extends downward in blotter.Permeable coagulation it is filled with in described permeable hole Soil.Described permeable surface layer is pervious concrete compound.

Specific construction process is as follows:

Stirring: in pervious concrete mixture, the denseness of cement mortar is relatively big, and negligible amounts, Can be wrapped in equably on aggregate for the ease of cement mortar, preferably use forced mixer, Mixing time is more than 5 minutes；

Pouring: before pouring, roadbed must first moisten with water.Otherwise pervious concrete is fast Speed loss moisture can reduce adhesion strength between aggregate.Owing to mixture is more stiff, will mix and stir Good pervious concrete material is paved on roadbed；

Vibrate: should not strongly vibrate or tamp in casting process.Generally use low frequency flat board Vibrator gently shakes the pervious concrete compound after paving, but must be noted that to use high frequency Vibrator, otherwise can make concrete the most closely knit and reduce porosity, affect permeable effect. High speed vibrator also can make cement slurry show to isolate from coarse aggregate, bottom inflow simultaneously Form an impermeable stratum, make material lose water penetration

Roll-in: after vibrating, solid steel pipe or light-duty road roller should be used further to be compacted, Flatten, pervious concrete mix, it is contemplated that the conditions such as the denseness of mix and environment temperature, Repeatedly roll-in may be needed, it should be noted that roller must be cleared up before roll-in, with anti-stick Aggregate；

Maintenance: pervious concrete owing to there is a large amount of hole, easy dehydration, be dried quickly, institute Extremely important with maintenance.Application plastic sheeting or colour bar cloth cover road surface and side in time, with Ensureing humidity and the abundant aquation of cement, pervious concrete should be supported after being cast in daystart watering Protect, during trickle, concrete surface should not be flung with pressure water column, so can take away some cement Slurry, causes the position that some are weaker, but directly can water from top to bottom in the case of normality Water；

Finished product: the wet foster curing time of overlay film of pervious concrete is no less than 7 days, finally sprays One layer of water permeable concrete special sealer so that it is perception effect tends to perfect.

Use ecological permeable road surface of the present invention that rainwater can be made to pass through the original runoff in ground Bleed back to underground, can effectively reduce, recharge of groundwater, maintain belowground ecosystem to put down Weighing apparatus, prevents ground settlement and road surface from subsiding, the urban environment of Creating Comfort, recovers soil Original function, keeps stablizing of nature biotechnology chain；Rainwater is permeable by this porous pavement Path is seeped into underlying soil under directly, not only alleviates the discharge pressure of urban pipe network but also make rain Water under ooze during obtained the filtration, purification of soil layer, alleviate rivers,lakes and seas etc. natural The pollution that water body produces because of road surface runoff；Solar heat and surrounding is effectively absorbed by soil Other heats discharged, simultaneously when natural environment temperature constantly reduces again can by before The heat of storage is released, and largely reduces the recovery capability of nature；Porous pavement The loose structure used, can effectively absorb all kinds of with external environment of automobile, motorcycle and traffic Noise, is effectively improved city noise and pollutes.
