Abstract

The invention belongs to the technical field of pavement construction, and particularly relates to a water-permeable brick and a preparation method thereof, and a pavement construction technique. Compared with the prior art, the water-permeable brick has favorable physical properties and water permeability. The water-permeable brick prepared by using the pulverized graded construction wastes as the aggregate can implement recycling of construction wastes, and the preparation cost of the water-permeable brick can be lowered. The water-permeable brick pavement uses the water-permeable bricks with favorable water drainage and seepage actions as the paving material, so that rainwater can quickly seep into the bearing layer and directly seep into the underground soil layer, thereby supplementing moisture to the soil layer and improving the growth conditions of ground plants. The water-permeable brick pavement is beneficial to relieving the urban heat island effect, regulating the urban climate, reducing the PM2.5 in the air and preventing the pavement from water accumulation.

Description

technical field [0001] The invention belongs to the technical field of pavement construction, and in particular relates to a permeable brick, a preparation method thereof and a pavement construction process. Background technique [0002] At present, more than 80% of the urban surface is covered by concrete pavements of buildings, and the temperature in urban areas is 2-3 degrees Celsius higher than that in suburban and rural areas, resulting in the so-called "heat island phenomenon". With the advancement of science and technology, human beings have higher and higher requirements for maintaining the harmony between the environment and nature in daily engineering construction. The inability of rainwater to seep into the ground for a long time has brought many social problems to the ecological environment of the city: the groundwater level in the city has dropped, and the replenishment of the underground soil by rainwater has been blocked, thereby affecting the growth of plants...
