Abstract

The utility model relates to a permeable tile for concrete pavement, which has a three-level structure with safe edge, finish layer and bedding made by a process of three distributions and one-time molding. The safe edge increases the strength of the tile and resistance to impact. The bedding and finish layer are in sand-free (low-sand) porous concrete, featuring high water permeability. The aggregate in the finish layer is finer than that in the bedding, leading to smaller size of the holes in the finish layer, contributing to capturing the external dust and preventing the internal permeable voids from blockage. The dust arranged on the finish layer is easy to clean by heavy rains or by washing with water gun. With high strength and permeability, the permeable tile for concrete pavement is suitable for the pavement of footpath with mild load or roads with light traffic.

Description

The permeable concrete pavior brick

Affiliated technical field

The utility model belongs to a kind of water permeability road brick.

Background technology

The permeable concrete ground surface material has the advantage of many ecological aspects, under the mankind sought to instruct with natural coordination, maintaining ecological balance and development thought, some developed countries such as America and Europe, Japan began one's study from the eighties in last century and develop the water-permeable pavement material.Since the nineties in last century, domestic the permeable concrete ground surface material has been begun to study.Permeable concrete adopt not to have the preparation of (lack) sand concrete, but the permeable concrete brick for preparing with conventional method, material is single coarse aggregate, the surface roughness height, and the top layer aggregate peels off easily when being subjected to external force, and permeable hole is easily stopped up by earth.

Summary of the invention

Wear no resistance in order to overcome general pervious concrete brick, easy blocked shortcoming, the utility model provides a kind of permeable concrete pavior brick with multilevel hierarchy.

The technical scheme that its technical problem that solves the utility model adopts is: adopt special process, three clothes form safe edge, bed course and top layer respectively; A compression moulding.Safe edge structural strengthening brick strength improves its shock-resistant ability; Nothing (lacking) sand porous concrete is all adopted on bed course and top layer, has high water permeability; The top layer aggregate is more tiny than bed course aggregate, causes permeable aperture, top layer also little, is beneficial to interception external source dust, prevents that inner permeable hole from stopping up, and the dust layer that the top layer is gathered is easy to remove under high heavy showers or the flushing of hydraulic giant from the beginning.

Its manufacture craft is: at first smear cement mortar at the inboard wall of mould, form the slope shape safe edge, the wide 2～3cm in bottom; Fill the bed course raw material to mould inside by the groove area that the safe edge mortar forms then, compacting is wiped out; Then add the top layer raw material that stirs, floating with the compacting of plate vibration machine; Preparation is finished after maintenance after a while can be come into operation.

The beneficial effects of the utility model are the anti-wear performances that improved the concrete permeable pavior brick, and prolong its permeable life-span.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1. the manufacture craft schematic diagram of the utility model permeable concrete pavior brick;

Fig. 2. the side schematic view of permeable concrete pavior brick;

Fig. 3. the schematic surface of permeable concrete pavior brick;

Fig. 4. the schematic bottom view of permeable concrete pavior brick;

Fig. 5. a kind of structure pattern of urban water-through concrete road.

Among the figure, 1. mortar safe edge, 2. water permeability bed course, 3. water permeability top layer, 4. permeable brick, 5. geotextiles, 6. compacting rubble, 7. diafiltration soil.

Safe edge (1), bed course (2) adopt different concrete materials and proportioning respectively with top layer (3): the safe edge mortar mainly contains cement, river sand and water to be formed, and concrete match ratio is: water: cement: river sand=0.45～0.55: 1: 2～4; Course mainly contains cement, river sand, rubble, water reducing agent and water to be formed, and concrete match ratio is: water: cement: water reducing agent: river sand: rubble=0.30～0.50: 1: 0～2.5%: 0～2: 3～8; The top layer mainly contains cement, river sand, permeable haydite, water reducing agent and water to be formed, and concrete match ratio is: water: cement: water reducing agent: river sand: permeable haydite=0.45～0.65: 1: 0～2.5%: 1～2: 2～3.

Manufacture craft is seen Fig. 1, specifically describes as follows: at first smear safe edge mortar (1) on the inboard wall of mould; The groove area fill-in pad layer material (2) that forms by the safe edge mortar to mould inside then, compacting is wiped out; Secondly on bed course, add skin-material (3), floating with dull and stereotyped trowelling machine compacting; After preparation is finished, carry out maintenance by the conventional curing condition of concrete products.

After maintenance was finished, three (side, surface, bottom surface) views of the outward appearance of this permeable concrete were seen Fig. 2 respectively, Fig. 3 and Fig. 4.Use this permeable concrete pavior brick make up city water permeability road using method can be with reference to figure 5: at the thick about 5 centimeters rubble in the ground upper berth of the road of handling well yet to be built, and compacting; Then lay geotextiles thereon; Permeable brick is laid on the rubble and gets final product.

(material therefor unit is specific embodiment: Kg)

Water 1Kg, cement 2Kg, river sand 6Kg are stirred the back (be 30 * 30 * 8cm) the inboard domatic safe edges of evenly smearing the wide 3cm in bottom at three moulds; With water 1.6Kg, cement 4Kg, water reducing agent 0.06Kg, river sand 4Kg, rubble 20Kg mix the back thoroughly and fall in three moulds that coat safe edge, and with the permeable bed course of the floating formation of plate vibration machine, approximately have 0.5cm apart from the mould top this moment; Water 0.33Kg, cement 0.6Kg, water reducing agent 0.009Kg, permeable haydite 1.2Kg, river sand 1.2Kg are stirred, spread upon on the bed course as permeable top layer, with floating the putting in order of dull and stereotyped trowelling machine vibration pressure.Cover 24 hours recession thin films with plastic sheeting after preparation is finished, moved into the maintenance of maintenance room 28 days.

In above-mentioned material: cement is selected Portland cement for use, and the cement that the embodiment of the invention adopts is the new brand of portland cement CA-32.5 of Wuhan China; The FDN-5 type early strength water-reducing agent that water reducing agent selects for use Wuhan Hao Yuan company to produce; Sand grains footpath, river Φ 1～2mm; Rubble is that particle diameter is the broken green stone of Φ 5～20mm; Permeable haydite is the ball-shaped high-strength ceramic granule that Yichang mound haydite development corporation, Ltd. produces, Φ 2～3mm.
