Technical field
The present invention relates to one " change " process in vain black in Pavement Improvement construction method, the particularly remodeling method of the region such as city trees and shrubs, parking lot cement concrete pavement.
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 transformation of the area road such as city trees and shrubs, parking lot occupies certain ratio.Conventional pav adopts pitch, concrete, stone slab or cement brick to lay mostly, therefore is 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, and during rainfall, rainwater is directly processed as sewage, has blocked rainwater supplementing underground water, has been unfavorable for the water circulation of natural environment.And for the not smooth area of drainage system, rain, sewage, easily in road surface alluvial, have a strong impact on municipal sanitary after dissolving in household garbage.In addition, hard surfacing easily absorbs, store and reflect solar heat, and ground average temperature is raised, the formation of aggravation urban heat land effect, thus causes environment and ecological negative effect, is 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 exploring development of new, and therefore pervious concrete also arises at the historic moment.Compared with conventional pav material, pervious concrete pavement has permeable, ventilative, adjustment urban climate, advantage such as reduction surface temperature, alleviating urban heat island phenomenon etc.; Simultaneously, urban groundwater resource can be supplemented, 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 creating quiet comfortable traffic environment, pervious concrete effectively can alleviate the problems such as the 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.The sustainable development of pervious concrete to urban ecological environment is significant.
Pervious concrete is used for road reformation engineering and mainly utilizes this material to be different from the water permeability of ordinary concrete, and therefore, how effectively improving its water permeability is the main points that each construction corps considers.Investigation display, in existing road reformation engineering, the constructing structure method of pervious concrete pavement mainly directly covers and builds pervious concrete on original cement concrete pavement.
Summary of the invention
The object of the invention is the water permeability being intended to utilize pervious concrete itself, adopt the construction method more optimized to promote the water permeability that cement concrete pavement changes 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 is carried out according to the following steps successively:
A, according to local conditions determination pervious concrete porosity P, and prepare corresponding pervious concrete;
B, evenly to hole on cement concrete pavement, and guarantee that cement concrete pavement layer is run through until roadbed in each hole, described hole is made up of equally distributed macropore and the aperture be evenly distributed on around macropore, and the quantity of macropore is far fewer than the quantity of aperture, orifice area sum and cement concrete pavement area ratio are called cement concrete pavement percent opening Φ, then need Φ to be greater than P;
C, cement concrete pavement layer after piercing lay geotextiles, and at chance macropore aperture place by geotextiles opening, openings of sizes and macropore aperture in the same size, make the through geotextiles of macropore;
D, the geotextiles upper pervious concrete surface layer laid, and pervious concrete is tamped in macropore;
Just pervious concrete pavement is formed after E, maintenance.
Further scheme to be the quantity of aperture the be 5-20 of the quantity of macropore doubly.
In the present invention:
Pervious concrete in macropore and pervious concrete surface layer monobloc cast, rainwater can penetrate into lower soil by macropore; Meanwhile, top pervious concrete surface layer and bottom cement concrete pavement layer are formed occlusion structure by " post " that the pervious concrete in macropore is formed, thus, " post " should play the overall structural effect of strengthening.
Keyhole formation water-permeable passage, strengthens water permeable ability.
This structure forms the water-permeable passage of size two kinds of diameters respectively, makes whole road surface can both be permeable, ensure that the water permeable ability of pervious concrete pavement.
The isolation of geotechnique's layer of cloth, impurity screening, avoid blocking water-permeable passage.
Water-permeable passage is communicated with roadbed, plays directly permeable effect.
And in the past in road reformation, most of construction method directly lays pervious concrete on Portland Cement Concrete Surface Course, can not reach the permeable effect of expection like this, can not ensure the globality of structure, easily occurs the phenomenon of Local Cracking.
Porosity P and percent opening Φ mainly determines according to situations such as local geology, weathers, particularly amount of precipitation.
The quantity of the quantity of aperture and size, macropore and size, pitch of holes etc., except should meeting percent opening Φ and requiring, also should be determined according to combined factors such as the thickness of Portland Cement Concrete Surface Course, intensity.Experiment shows, the quantity of aperture is 5-20 times of the quantity of macropore.
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 use, well can merge with environment.The method utilizes rational topology layout, improve 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 is closely engaged with Old cement concrete, and the overall performance of road structure is guaranteed.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, minor diameter two kinds of water-permeable passage forms are set, both can have strengthened the bulk strength on transformation road surface, the requirement of water permeability can be met again.
