Description
Technical field
The utility model relates to the full pervious concrete pavement structure of regenerated aggregate way, be mainly used in the regions such as residential quarters sidewalk, nonmotorized vehicle lane and parking lot, for the utilization of construction waste concrete regenerating and pervious concrete structure provide technical condition in green building outdoor environment transformation application, belong to civil construction green construction technology.
Background technology
Green building save land with outdoor environment in highway construction preferably adopt pervious concrete.In Process of Urban Development, there are a large amount of existing community transformations or remove and rebuild, bringing the handling problems that produces a large amount of building wastes thereupon.About the regeneration of building waste, particularly remove concrete regeneration in member and there is good social and economic effects.In design and construction practice, consider the regeneration of discarded concrete, discarded concrete in building demolition is processed through decomposing fragmentation, obtain building regenerated aggregate (coarse-fine aggregate) and can replace the sandstone in conventional concrete, configuration regeneration concrete, on this basis, interspace in advance by inside concrete, form continuous passage, configuration regenerated aggregate pervious concrete, can fully utilize the technology crossed dominance of regeneration concrete and pervious concrete, the regenerated aggregate pervious concrete configuring, be applied to residential quarters road, sidewalk, the regions such as parking lot and place, there is good social and economic effects.
Also there is at present the hysteresis of technological gap and research about the application of regenerated aggregate pervious concrete, although have wide market prospects and application demand, but about regenerated aggregate pervious concrete there is the technological constraint of all too many levels such as joint structure way, configuring technical, quality control, physical and mechanical property in the application in road, lacks the support of technical specification and standard.
Summary of the invention
The utility model provides a kind of regenerated aggregate full pervious concrete pavement structure, makes full use of concrete regeneration aggregate and replaces sandstone
material-saving advantagein the advantage aspect water permeability, the full pervious concrete pavement of the regenerated aggregate of configuration is specially adapted to region and the places such as residential quarters road, sidewalk, parking lot with pervious concrete.
The utility model is realized with following technical scheme: the full pervious concrete pavement structure of a kind of regenerated aggregate, and it comprises the pervious concrete surface layer, concrete dynamic modulus cement reclaimed concrete aggregate basic unit, grating reclaimed concrete aggregate basic unit and the roadbed that distribute successively from top to bottom; Described pervious concrete surface layer is that strength grade of concrete is the regenerated aggregate pervious concrete surface layer of C20-C25, coefficient of permeability 2.5-4.0mm/s, porosity 10%-15%, in regenerated aggregate pervious concrete surface layer and basic unit, adopts Aggregate of recycled concrete.
In described pervious concrete surface layer, Aggregate of recycled concrete particle diameter is 5mm-20mm.
The thickness of described pervious concrete surface layer is 80-100mm.
Described concrete dynamic modulus cement reclaimed concrete aggregate basic unit adopts the building regenerated aggregate that particle diameter is 5mm-37.5mm, and reclaimed concrete aggregate is by cement-bonded formation concrete dynamic modulus cement regenerated aggregate basic unit.
The thickness of described concrete dynamic modulus cement reclaimed concrete aggregate basic unit is 150mm-200mm.
Described grating reclaimed concrete aggregate basic unit adopts the reclaimed concrete aggregate that particle diameter is 5mm-37.5mm to lay, and regenerated aggregate groundwork thickness is 100-150mm.
Described roadbed is natural soil roadbed.
The beneficial effects of the utility model are, the full pervious concrete pavement structure applications of described regenerated aggregate, in region and places such as residential quarters road, sidewalk, parking lots, can effectively reduce excess surface water, facilitates walk, improve ground flora growing environment, reduce heat island effect.Make full use of regenerated aggregate, turn waste into wealth, reduce energy consumption, energy-saving and emission-reduction.
Brief description of the drawings
Fig. 1 is the full pervious concrete pavement structural representation of regenerated aggregate.
In figure: 1-regenerated aggregate pervious concrete surface layer; 2-concrete dynamic modulus cement reclaimed concrete aggregate basic unit; 3-grating reclaimed concrete aggregate basic unit; 4-roadbed.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is described further.
In the present embodiment, adopt the discarded concrete of tearing down and building community as raw material, its Original concrete strength grade is C25-C40, after crushing and screening processing, form the reclaimed concrete aggregate of satisfying the demand, adopt this building aggregate configuration regenerated aggregate concrete and regenerated aggregate basic unit, way according to accompanying drawing 1 is implemented, and is applied to the construction of community sidewalk.
As shown in Figure 1, roadbed 4 is rammed earth ground, on roadbed 4, being grating regenerated aggregate basic unit 3, is concrete dynamic modulus cement reclaimed concrete aggregate basic unit 2 in grating reclaimed concrete aggregate basic unit 3, in concrete dynamic modulus cement reclaimed concrete aggregate basic unit 2, is regenerated aggregate pervious concrete surface layer 1.
It is the building reclaimed concrete aggregate of 5mm-37.5mm that grating regenerated aggregate basic unit 3 adopts particle diameter, and regenerated aggregate basic unit 3 thickness are 100mm.Grating regenerated aggregate basic unit 3 construction qualities meet the requirements, and after acceptance(check), lay concrete dynamic modulus cement regenerated aggregate basic unit 2 thereon.
Concrete dynamic modulus cement reclaimed concrete aggregate basic unit 2 adopts regenerated building concrete aggregate to replace rubble or gravel configuration concrete dynamic modulus cement reclaimed concrete aggregate to form basic unit, and building reclaimed concrete aggregate particle diameter is 5mm-37.5mm, and groundwork thickness is 200mm.
After 2 acceptance(check)s of concrete dynamic modulus cement reclaimed concrete aggregate basic unit, lay reclaimed concrete aggregate pervious concrete surface layer 1 thereon.Regenerated aggregate pervious concrete surface layer 1 is positioned at upper strata, road surface, this surface layer is regenerated aggregate pervious concrete, this pervious concrete aggregate adopts reclaimed concrete aggregate, particle diameter is 5mm-20mm, described regenerated aggregate pervious concrete strength grade is C20, coefficient of permeability 3.5mm/s, porosity 12%, surface thickness is 100mm.
In embodiment, adopt the full pervious concrete pavement of regenerated aggregate, rainwater infiltrates concrete dynamic modulus cement reclaimed concrete aggregate basic unit very soon by regenerated aggregate pervious concrete surface layer, then continues to penetrate into ground by grating reclaimed concrete aggregate basic unit.Owing to having adopted full impregnated water-bound structure way, rainy day, rainwater can enter underground fast, excess surface water obviously reduces, the rainwater infiltrating has supplemented underground water, these are for rainy day walk, reduce the city pressure that drains off floodwaters, recharge of groundwater exploitation, improve community plant growth environment, reduction heat island effect etc. has more significant effect.Utilize discarded concrete to produce regenerated aggregate, be applied in road concrete, being conducive to turns waste into wealth, and reduces energy consumption.The advantage of the full pervious concrete pavement of regenerated aggregate structure way is integrated regeneration concrete and pervious concrete, is applicable to region and the places such as residential quarters road, garden path.
