Abstract
The utility model relates to a permeable pavement brick produced by building solid waste aggregates. The pavement brick comprises a surface layer (1), a base body layer (2) produced by recycled aggregates and a base body strengthening layer (3) which are sequentially arranged from a top surface to a bottom surface, wherein a metal net (4) is arranged in the base body strengthening layer (3); and the recycled aggregates are particles which are formed by processing concrete, mortar, stone or tile and the like in building wastes. The building wastes are fully used as aggregates, so that the pavement brick has not only good water permeability but also pressure resistance, fracture resistance and wear resistance.
Description
Technical field
The utility model relates to the pervious concrete road pavement brick technical field of structures, relates in particular to the pervious concrete road pavement brick that utilizes the building solid castoff aggregate.。
Background technology
In recent years, the building solid castoff annual emissions of China approximately 4500 * 10
4～6000 * 10
4T, this numeral does not also comprise the building waste of burying nearby.Excessive building waste will inevitably produce environmental problem, causes huge financial burden for again simultaneously Construction unit and city.How correctly to process and to be recycled as much as possible, to have become review on management of modern cities person's a important topic.
Pervious concrete road pavement brick is a kind of novel high osmosis ground surface material, is made through special process by the gathering materials of certain grating, cement, extraordinary adhesive material and water etc.Compare with the Common Concrete Pavement brick, maximum characteristics are that coefficient of permeability is large.When raining, rainwater can in time permeate the ground by pavior brick, perhaps is stored in the space of pavior brick, reduces surface gathered water.Pervious concrete road pavement brick can be widely used in the laying on the road surfaces such as dwelling house, garden, park, square, botanical garden, gardens, factory region, parking lot, tree well, greenhouse, pavement and light duty traffic highway, has good society, environment and ecological effect.
The physical and mechanical property General Requirements of pervious concrete road pavement brick reaches following index: (1) compressive strength 〉=30.0MPa; (2) rupture strength 〉=3.5MPa; (3) coefficient of permeability 〉=2.0mm/s(4) mill is cheated length≤35mm.Nearly all do not reach above-mentioned technical requirements and produce pervious concrete road pavement brick with the building solid castoff aggregate at present.Main cause is: a, due to the building solid castoff aggregate mainly by discarded concrete, brickbat, watt, the regeneration such as glass, pottery obtains after crushing and screening, so its crush index value apparently higher than natural aggregate, shows that intensity is lower; The mud content of b, building solid castoff aggregate is far above natural aggregate, so must cause its concrete products strength decreased, contraction to increase; C, tradition utilize the pervious concrete road pavement brick of building solid castoff aggregate production to add base layer structure for surface layer, and foundation base intension is on the low side, shrink greatly, and the service life of product is lower.
Summary of the invention
The purpose of this utility model is to solve the problem that prior art exists, and provides a kind of building waste that takes full advantage of as aggregate, not only good water permeability, and resistance to compression, anti-folding, wear-resisting permeable pavement brick.
The purpose of this utility model is achieved by the following technical solution:
Base layer, matrix enhancement layer that a kind of permeable pavement brick of making of the building solid castoff aggregate, this pavior brick comprise the surface layer that sets gradually from upper surface to bottom surface, manufacture with regeneration aggregate are provided with wire lath in matrix enhancement layer inside; Described regeneration aggregate is the particle that is processed by the concrete in building waste, mortar, stone or brick and tile etc.
Regeneration aggregate described in the utility model is regenerated coarse aggregate and/or recycled fine aggregate; Described base layer adopts portland slag cement, 5mm-16mm continuous size fraction regenerated coarse aggregate, recycled fine aggregate, water reducing agent to mix cast and makes.The thickness of base layer is 30mm-50mm.Described enhancement layer is made by C40 level pea gravel concreten slip coated metal net, and the thickness of enhancement layer is 15mm-20mm, manufactures the wire diameter 6mm-8mm of wire lath.
The utility model is due to the three layers structure that has adopted surface layer, base layer, matrix enhancement layer, and the base layer of manufacturing take building solid castoff as aggregate is set to the intermediate layer, can take full advantage of building solid castoff, also can guarantee water permeability preferably.Surface layer can adopt the material identical with existing ordinary concrete permeable pavement brick, so that its surperficial compressive strength, anti-wear performance meet the relevant national standard requirement.Because adopting the slip coated metal net of the above rank ordinary concrete preparation of C40, makes the matrix enhancement layer, therefore the permeable pavement brick rupture strength of making also can reach the requirement of relevant national standard fully.Surface layer of the present utility model, base layer and matrix enhancement layer all can guarantee good water permeability, and the whole water permeability of product also can reach the relevant national standard requirement.
The utility model is by the layers of material composite manufacturing pervious concrete road pavement brick of different qualities, both consumed in a large number building solid castoff, reduced the production cost, improved environment, its product physical and mechanical property also can reach the requirement of relevant national standard.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of matrix enhancement layer.
The specific embodiment
As shown in Figure 1 and Figure 2, base layer 2, matrix enhancement layer 3 that the utility model comprises the surface layer 1 that sets gradually from upper surface to bottom surface, manufactures with regeneration aggregate are provided with wire lath 4 in matrix enhancement layer 3 inside; Described regeneration aggregate is regenerated coarse aggregate and/or recycled fine aggregate.According to national sector standard JGJ/T 240-2011 " regeneration aggregate application technology rules ", regenerated coarse aggregate refers to be processed by the concrete in building waste, mortar, stone or brick and tile etc., and particle diameter is greater than the particle of 4.75mm.Recycled fine aggregate refers to be processed by the concrete in building waste, mortar, stone or brick and tile etc., and particle diameter is less than the particle of 4.75mm.Described building solid castoff reworked material by discarded concrete, brickbat, watt, the regeneration such as glass, pottery are after crushing and screening.Surface layer 1 adopts the prior art material to make, for example, adopt PO 42.5 Portland cements, the artificial rubble of 5mm-10mm single-grade, Machine-made Sand, water reducing agent and painted with inorganic pigment by certain more formulated than being listed as.The thickness of surface layer is generally 15mm-20mm.Base layer 2 adopts portland slag cement, 5mm-16mm continuous size fraction regenerated coarse aggregate, recycled fine aggregate, water reducing agent to mix cast and makes, for example, adopt PS 32.5 portland slag cements, 5mm-16mm continuous size fraction regenerated coarse aggregate, recycled fine aggregate, water reducing agent by necessarily formulated than row, the thickness of base layer 2 is generally 30mm-50mm.Enhancement layer 3 is made by C40 level pea gravel concreten slip coated metal net 4, and the thickness of enhancement layer 3 is 15mm-20mm, manufactures the wire diameter 6mm-8mm of wire lath 4.Wire lath adopts gauze wire cloth usually.
