Background technique
Currently, the non-permeable material such as cement, pitch, marble is mostly used to be laid with ground in urban construction greatly, these are hard
Changing road surface keeps the heat of earth's surface and air, exchange of moisture highly difficult, the poor ability of Natural regulation urban ground temperature and humidity,
Earth's surface absorbs heat difficulty, causes to retain a large amount of waste heats in city space, and ground can also largely be reflected, and radiates solar thermal energy, from
And lead to the city nocturnal temperature phenomenon higher than countryside nocturnal temperature occur.Moreover, hard surface can prevent rainwater in the rainy day
Directly permeate the ground, cause ponding everywhere, influence the comfortableness and security of road, at the same blocked rainwater directly addedly under
The approach of water makes Urban Underground water level be difficult to, and directly affects the healthy growth of urban surface vegetation, and greening is difficult, aggravates
The drought and water shortage problem in city；And ponding injects rivers after pouring in sewer, has aggravated the row of sewerage system and rivers
Let out burden, ground is again extremely dry when fine day, and dusty, environmental degree of comfort substantially reduces.
To solve the above-mentioned problems, it is proposed permeable brick product in the market.Water-permeable brick with its many excellent performance gradually
It is accepted by people, it has been widely used in the ranges such as square, pavement, cell pavement, garden architecture at present.Water-permeable brick
Use restored natural storage capacity while beautifying the environment, prevented depletion of groundwater；Improve vegetation living environment；
Atmospheric humidity is adjusted, air is purified, restores the water circulation system of earth's surface.
A kind of pottery sand water-permeable brick and preparation method thereof disclosed in Chinese patent CN201510808633.X, the pottery sand is permeable
