Embodiment 4
The preparation method of tailing ecology sponge water-permeable brick of the embodiment 1 into embodiment 3, which is characterized in that including as follows
Step:
A prepares raw material: 1 raw material proportioning of fine and close pervious bed according to embodiment 1 into embodiment 3, loose pervious bed 2 respectively
Raw material proportioning and water conservation 3 raw material proportioning of pervious bed prepare；
B assembly mold and stone: it is fine and close permeable in mold according to the ratio between thickness to be that 1:1.5:1 successively mats formation from bottom to top
1 raw material of layer, 2 raw material of loose pervious bed and water conservation 3 raw material of pervious bed；
C compacting: pressure when compacting is 60Mpa；
D low temperature is steam-cured: conserving 24 hours at 30-60 DEG C, relative humidity 75%.
Anti- folding according to tailing ecology sponge water-permeable brick of the GB/T 25993-2010 testing example 1 into embodiment 3 is strong
Degree, tensile splitting strength, coefficient of permeability, frost resistance and wearability, test result are as shown in table 1:
Table 1
As can be seen from Table 1: by adjusting the grain composition of raw material and the quality proportioning of raw material, it is strong that anti-folding can be improved
Degree, tensile splitting strength and coefficient of permeability, and frost resistance and wearability can be improved.
Further, since although the tailing ecology sponge water-permeable brick in the present invention is integrally formed, but from top to bottom successively
Are as follows: fine and close pervious bed 1, loose pervious bed 2 and water conservation pervious bed 3.The of a relatively loose pervious bed 2 of fine and close pervious bed 1 is finer and close, hole
Gap is smaller, can be effectively prevented dust in practical applications in this way and block on tailing ecology sponge water-permeable brick upper surface
Micropore, it is ensured that rainwater can still be penetrated by the tailing ecology sponge water-permeable brick after long-time use.It is loose permeable
For 2 relatively compact pervious bed 1 of layer, compactness is poor, and hole is relatively large, it is ensured that rainwater passes through energy after fine and close pervious bed 1
Enough quickly infiltrations downwards, are effectively prevented from when rainwater penetrates into slower and flow away along tailing ecology sponge water-permeable brick upper surface.
It being retained for the relatively compact pervious bed 1 of pervious bed 3 and loose pervious bed 2, coefficient of permeability is smaller, but when rainfall is smaller
It waits, can effectively prevent rainwater from permeating down by the water conservation continuation of pervious bed 3 and be lost, the city road less suitable for rainfall
Road is laid with, and can play the role of adjusting urban air humidity so after the rain；When rainfall is larger, rainwater is in itself weight
It is permeated under the action of hydraulic pressure in the loose pervious bed 2 of power and upper layer and fine and close pervious bed 1, can successfully pass through water conservation pervious bed
3 and penetrate into the soil below the tailing ecology sponge water-permeable brick.It can be by adjusting fine and close pervious bed 1, loose permeable
The coefficient of permeability and relative thickness of layer 2 and water conservation pervious bed 3, so that the tailing ecology sponge water-permeable brick is biggish in rainfall
When can play the role of smoothly it is permeable, reduce rain water runoff and played when rainfall is lesser water conservation moisturizing work
With.By test find, according in embodiment 3 raw material proportioning and raw material granularity combine, in mold from bottom to top according to
The ratio between thickness be 1:1.5:1 successively mat formation fine and close 1 raw material of pervious bed, 2 raw material of loose pervious bed and water conservation 3 raw material of pervious bed, system
The tailing ecology sponge water-permeable brick obtained when water film thickness on an upper is more than 1mm, can overcome water conservation pervious bed 3
The resistance of rainwater is smoothly penetrated into lower soil.
Above-described embodiment is only intended to clearly illustrate the invention example, and not has to the invention
The restriction of body embodiment.For those of ordinary skill in the art, it can also make on the basis of the above description
Other various forms of variations or variation.There is no necessity and possibility to exhaust all the enbodiments.It is all of the invention
Guarantor of any obvious changes or variations extended out within spirit and principle still in the invention claim
It protects among range.
