Background technology
Along with the continuous progress of science and technology, ecological, environmental protective construction coming into one's own all the more, different kinds of roads retrofit work just carries out ruly, and wherein, the area road transformations such as city trees and shrubs, parking lot occupy certain ratio.Tradition road surface adopts pitch, concrete, stone slab or cement brick to lay mostly, therefore be called as hard surfacing.Its advantage is that road surface is neat, intensity is high, good endurance, and maximum shortcoming is waterproof, and draining relies on underground sewer, during rainfall, rainwater is directly processed as sewage, has blocked rainwater to the supplementing of underground water, and is unfavorable for the water circulation of natural environment.And for the not smooth area of drainage system, rain, sewage is easily in road surface alluvial, have a strong impact on municipal sanitary after dissolving in household garbage.In addition, hard surfacing easily absorbs, stores and reflect solar heat, and ground average temperature is raise, the formation of aggravation urban heat land effect, thus cause environment and ecological negative effect, be unfavorable for the ecological homeostasis and environmental protection.
In order to solve this series of problem, the researchers of various countries are actively thinking deeply the paving material of exploring development of new, and therefore pervious concrete also arises at the historic moment.Compare with traditional ground surface material, that pervious concrete pavement has is permeable, ventilative, regulate urban climate, reduce the advantages such as surface temperature, alleviating urban heat island phenomenon; Simultaneously, can supplement urban groundwater resource, maintain the soil moisture, improve the life condition of urban surface plants and soil biology, be conducive to the ecological homeostasis, and pervious concrete can absorb the noise that vehicle to run produces, be conducive to create quiet comfortable traffic environment, pervious concrete can effectively alleviate the problems such as road drainage system burden that rainwater causes.
Detection shows, when pervious concrete terrace porosity reaches 15%-25%, its permeable speed reaches 31118L/m
2/ h-51196L/m
2/ h, discharge rate is high.Pervious concrete is significant to the sustainable development of urban ecological environment.
Pervious concrete is mainly to utilize this material to be different from the water permeability of ordinary concrete for road reformation engineering, and therefore, how effectively improving its water permeability is the main points that each construction corps considers.Investigation demonstration, in existing road reformation engineering, the constructing structure method of pervious concrete pavement is mainly directly to cover and build pervious concrete on original cement concrete pavement.
Summary of the invention
The object of the invention is to be intended to utilize the water permeability of pervious concrete itself, adopt the construction method of more optimizing to promote cement concrete pavement, to change the water permeability of pervious concrete pavement, reach permeable effect better.
The present invention is achieved in that
Cement concrete pavement changes a method for pervious concrete pavement into, it is characterized in that the method carries out according to the following steps successively:
A, according to local conditions, determine pervious concrete porosity P, and prepare corresponding pervious concrete;
B, evenly boring on cement concrete pavement, and guarantee that each hole runs through cement concrete pavement layer until roadbed, described hole is by equally distributed macropore and be evenly distributed on macropore aperture around and form, and the quantity of macropore is far fewer than the quantity of aperture, orifice area sum and the ratio of cement concrete pavement area are called to cement concrete pavement percent opening Φ, need Φ to be greater than P;
On C, the cement concrete pavement layer after boring, lay geotextiles, and meeting place, macropore aperture by geotextiles opening, openings of sizes and macropore aperture are in the same size, make macropore connect geotextiles;
D, at the geotextiles upper pervious concrete surface layer of laying, and in macropore, tamp pervious concrete;
After E, maintenance, just form pervious concrete pavement.
The 5-20 of the quantity that the quantity that further scheme is aperture is macropore doubly.
In the present invention:
Pervious concrete in macropore and pervious concrete surface layer monobloc cast, rainwater can be penetrated into lower soil by macropore; Meanwhile, " post " that the pervious concrete in macropore forms forms occlusion structure by top pervious concrete surface layer and bottom cement concrete pavement layer, thereby, should " post " play the whole structural effect of strengthening.
Aperture forms water-permeable passage, strengthens water permeable ability.
This structure forms respectively the water-permeable passage of two kinds of diameters of size, makes the whole road surface can both be permeable, has guaranteed the water permeable ability of pervious concrete pavement.
The isolation of geotechnique's layer of cloth, impurity screening, avoid stopping up water-permeable passage.
Water-permeable passage is communicated with roadbed, plays directly permeable effect.
And in the past in road reformation, most of construction methods are directly on Portland Cement Concrete Surface Course, to lay pervious concrete, can not reach so the permeable effect of expection, can not guarantee the globality of structure, easily occur the phenomenon of Local Cracking.
Porosity P and percent opening Φ mainly determine according to situations such as local geology, weather, particularly amount of precipitations.
The quantity of the quantity of aperture and size, macropore and size, pitch of holes etc., except meeting percent opening Φ requirement, also should be determined according to combined factors such as the thickness of Portland Cement Concrete Surface Course, intensity.Experiment shows, the 5-20 of the quantity that the quantity of aperture is macropore doubly.
Advantage of the present invention:
The pervious concrete material of this structure itself is a kind of green material, maximum feature is its pervious function, in addition, the loose structure of material makes it have sound absorption reduction, absorb the effect of solar radiation, can also need to change concrete color according to using, can well merge with environment.The rational topology layout of the method utilization, improved constructing structure in the past can not utilize the present situation of pervious concrete water permeability completely, road structure is optimized more.With regard to structure itself, major diameter pervious concrete post and the tight interlock of old cement concrete pavement, be guaranteed the overall performance of road structure.The setting of geotechnique's layer of cloth not only can prevent aggregate blocking channel in work progress, and can isolate impurity, is convenient to follow-up cleaning.Meanwhile, major diameter, two kinds of water-permeable passage forms of minor diameter are set, both can have strengthened the bulk strength on transformation road surface, can meet again the requirement of water permeability.
