The pervious concrete precast component for road comprises a pervious concrete slab; the periphery of the pervious concrete slab is provided with a concrete layer; steel bars are pre-embedded in the pervious concrete slab; and parts of the steel bars extend out of the pervious concrete slab and the concrete layer. The pervious concrete precast component for road can effectively solve the municipal surface gathered water, ease the burden of municipal drainage system; and the modular design can resolve the problem traffic congestion of caused by slow road repair.
Description
Technical field
The disclosure relates generally to building field, relates in particular to a kind of road pervious concrete prefabricatedMember.
Background technology
Road surface, traditional cities is water-tight structure, and rainwater is shown to get rid of by road, and discharge capacity is limited,In the time running into heavy rain or heavy rain, rainwater easily collects on road surface, concentrate in a large number motor vehicle and fromOn runway, cause road surface ponding on a large scale.
Hardstand has several respects to the main harm of urban environment: the one, while raining, intercept completelyRainwater directly infiltrates through ground, has increased the weight of the burden of drainage pipeline, makes city once meeting rainfall simultaneouslyCompletely ponding, and when fine day, ground is very dried again, stirs up a cloud of dust; The 2nd, a large amount of reflections,Storage is stayed and is then discharged solar radiant heat, has greatly increased urban heat land effect, makes amenityDegree reduces greatly; The 3rd, after snowfall, easily freeze and skid, bring multiple inconvenience to people's tripEven dangerous, meanwhile, also cannot utilize precipitation to supplement urban groundwater. The 4th, directly affect cityCity's vegetation health, further increases the weight of arid, the water shortage status in city, forms the life of vicious circleState environment.
In existing pervious concrete, due to fine aggregate, workability and the mobility such as admixture sand notPoor, inside concrete space skewness, causes the pressure resistance of existing pervious concreteDegree and rupture strength can not meet the requirement on road surface, the therefore water penetration of pervious concrete and anti-foldingThe relation of compression strength becomes existing main direction of studying in industry, how to configure and meetsThe pervious concrete of road surface pressure-proof and snap-resistent intensity also becomes a difficult problem urgently to be resolved hurrily.
In sum, existing not yet have a kind of high strength permeable road concrete prefabricated components again.
Summary of the invention
In view of road surface in prior art is water-tight structure, rainwater is shown to get rid of by road, earial drainage energyThe defect that power is limited or deficiency, expect to provide a kind of road pervious concrete prefabricated components.
Provide a kind of road pervious concrete prefabricated components on the one hand, comprising: pervious concretePlate, described pervious concrete plate surrounding is furnished with concrete layer, pre-buried in described pervious concrete plateHave bar construction, described bar construction part is stretched out described pervious concrete plate and described concreteLayer.
Road in the present invention can effectively solve urban pavement with pervious concrete prefabricated componentsPonding, alleviates sewerage system burden; And be modularized design, can solve current roadTrimming speed is slow, thus the traffic blocking problem causing.
Brief description of the drawings
By read do with reference to the following drawings non-limiting example is done retouch in detailState, it is more obvious that the application's other features, objects and advantages will become:
Fig. 1-3 are pervious concrete prefabricated components structural representation for road in the present invention;
Detailed description of the invention
Below in conjunction with drawings and Examples, the application is described in further detail. Be appreciated that, specific embodiment described herein is only for explaining related invention, but not to thisBright restriction. It also should be noted that, for convenience of description, in accompanying drawing, only show withInvent relevant part.
It should be noted that, in the situation that not conflicting, the embodiment in the application and embodimentIn feature can mutually combine. Describe below with reference to the accompanying drawings and in conjunction with the embodiments this in detailApplication.
Please refer to Fig. 1 to Fig. 3, the invention provides a kind of road pervious concrete prefabricated components,It is characterized in that, comprising: pervious concrete plate 1, described pervious concrete plate surrounding is furnished with mixedSolidifying soil layer 3, is embedded with bar construction 2 in described pervious concrete plate, described bar construction 2Part is stretched out described pervious concrete plate 1 and described concrete layer 3.
Road in the present invention can effectively solve city on the one hand with pervious concrete prefabricated componentsCity's surface gathered water, alleviates sewerage system burden; On the other hand, the road in the present invention is usedConcrete prefabricated element is modularized design, can solve current road trimming speed slow, therebyThe traffic blocking problem causing.
Optionally, described pervious concrete plate is regular shape.
Optionally, described pervious concrete is rectangle. In the present invention, providing a kind of road usesPervious concrete prefabricated components, carry out modular making by pervious concrete, on the one hand in realityMore convenient in the work progress on border, and convenient to the trimming of road, alleviation trafficPressure; On the other hand above-mentioned prefabricated components are made to regular shape, more constructability; SeparatelyOutward, because compression strength and the rupture strength of pervious concrete plate are lower, road surface is easily damaged,Increase in the surrounding of pervious concrete plate the concrete layer that common high-strength concrete is made, strengthenedThe compression strength of prefabricated components and rupture strength.
Optionally, described concrete layer material is common high-strength concrete. In the present invention, body isPervious concrete plate, surrounding is distributed with common high-strength concrete layer, realizes between modulesSeparate, and easy to use in actual use.
Optionally, described pervious concrete is by cement, coarse aggregate rubble, water, high efficiency water reducing agentComposition, its mass ratio is: cement: coarse aggregate rubble: water: high efficiency water reducing agent is 20～25:81～85:4.2～4.8:0.5～0.8. Pervious concrete in the present invention is by cement, rubble, waterWith high efficiency water reducing agent composition, do not add the fine aggregates such as sand, in the concrete prefabricated element of making, depositIn even continuous space, thereby can reach permeable effect.
Optionally, described cement: coarse aggregate rubble: water: high efficiency water reducing agent mass ratio is 20～23:82～84:4.5:0.6～0.7. The also tool of pervious concrete prefabricated components that in the present invention, material is madeHave good compression strength and rupture strength, its test is as follows.
Optionally, described pervious concrete also comprises blend composition flyash. In the present invention by makingCarry out the preparation of pervious concrete prefabricated components with coarse aggregate rubble and blend composition flyash, makePrefabricated components afterwards have good water penetration.
