Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to a water permeable brick suitable for sponge city construction and a production method thereof.
Background
In urban construction, most urban pavements in China are paved by stone slabs, cement and cement square bricks, including sidewalks, bicycle lanes, suburb roads, open parking lots, grounds of courtyards and street roads, public squares and the like. In the country of construction 50 years ago, the American newspaper reported the Beijing royal well project of grandeur, but the American public response was: how to penetrate rainwater on the hardened pavement and how to solve the heat reflection of the pavement in summer. Today, the roadway and sidewalk paving of many cities is being conducted vigorously, and unfortunately the road water permeability problem is still neglected.
The hardened pavement has great harmfulness. The hardened pavement is neat and durable, but the biggest disadvantage is that the hardened pavement is waterproof. The road surface is impermeable, so that the supplement of rainwater to underground water is completely blocked during rainfall, and the descending underground water level is difficult to rise in cities depending on the underground water as drinking water sources; on the contrary, the rainwater runs off from the road surface to the drainage pipeline to be drained, so that the city becomes a water-deficient area with dry ground surface, the dust pollution of the city is aggravated, and the great difficulty is brought to the city greening due to the dry ground surface.
When raining, the rainwater is not smoothly discharged, and a water logging condition is formed in the streets and alleys of the cities, such as cities of Jinan, Nanjing, Chongqing, Hangzhou, Harbin and the like, or flood disasters are generated on the sides of the cities. And the rainwater silts on the road surface, on one hand, the rainwater can cause traffic jam and aggravate the pollution of the tail gas emission of the motor vehicle, on the other hand, the rainwater can be dissolved into a large amount of urban pollutants such as heavy metal discharged by automobiles, abrasion of tires, household garbage, dust and chemicals on the construction site, pesticides sprayed on urban grasslands and the like when flowing transversely, and the rainwater can be directly discharged into local rivers through pipelines and can cause pollution. In heavy rain, a water pit formed on the road surface often exists for several days, epidemic diseases are easily caused, and urban sanitation is greatly influenced.
The hardened pavement absorbs, stores and reflects the heat of the sun, and can increase the average temperature of the ground by several degrees. This can increase the sweltering heat in urban summer, reduces the comfort of urban life, increases the energy consumption of paying for cooling in urban life simultaneously. The hardened pavement also causes environmental and ecological negative effects, such as air exchange and air humidity reduction of the pavement, combined with increasingly heavy air pollution in cities, contributing to the formation of urban heat island effect: the ecological environment of local plants and animals is very harmful, so that the ground ecosystem and biological activities consisting of the plants and the animals are influenced; the hardened pavement separates the ecological space of the flora and fauna which grow dependently, which is extremely disadvantageous for protecting the small ecology in cities.
Therefore, in the ' guide opinion about promoting sponge city construction ' published by the office of the state department, ' the ' 2015 ' 75 document proposes that measures such as ' seepage, stagnation, storage, purification, use and discharge ' are comprehensively adopted through sponge city construction, so that the influence of city development and construction on the ecological environment is reduced to the maximum extent, and 70% of rainfall is absorbed and utilized on the spot. In 2020, more than 20% of the area of the urban built-up area meets the target requirement; by 2030, more than 80% of the area of the built-up area of the city meets the target requirement.
However, most of the existing water permeable bricks in the market use industrial pigments, so that the water permeable bricks are single in color, stiff, easy to weather, aging, low in strength and water permeability and far from meeting the standard requirements of high-standard outdoor landscape engineering.
