Problems solved by technology

On the one hand, the long-term failure of rainwater to seep into the ground has brought many social problems to the ecological environment of the city: the groundwater level in the city has dropped, the replenishment of the underground soil by rainwater has been blocked, and the growth of plants on the ground surface has been affected. The increase of PM2.5 particles in the air, the heavy rain caused serious road surface water, traffic jams, etc.; on the other hand, the runoff production and confluence time shortened, the rainwater washing capacity increased, and the runoff pollution load increased. Urban rainfall runoff pollution has become a source of water pollution. one of the main sources
[0005] However, the shape of the above-mentioned permeable bricks is fixed, the application form is limited, and it is inconvenient to replace after the water-permeable performance deteriorates

Abstract

The invention discloses a method for preparing a simulated pavement material, which is characterized in that it includes the following steps: A. Preparation of sludge biochar: domestic sewage sludge from a sewage treatment plant is subjected to anaerobic conditions at 500-600°C Carbonize for 3 to 5 hours, cool, grind, and sieve to obtain sludge biochar; B. Preparation of mixture: Mix sludge biochar, cement, river sand, and pigments evenly to obtain a mixture, pack it and send it to the construction site Production; C. Preparation of simulated paving materials: at the construction site, add water and stir the mixture evenly, pour it into the simulated mold, and demould after 12 to 24 hours to obtain the required simulated paving materials. Compared with the prior art, the simulated pavement material obtained by the preparation method of the present invention can be produced on site according to project requirements, and is easy to operate and flexible in application form.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a method for preparing a simulated paving material. Background technique [0002] With the acceleration of the urbanization process, more than 80% of the urban surface area is covered by building concrete, and the urban impervious area increases sharply. On the one hand, the long-term failure of rainwater to seep into the ground has brought many social problems to the ecological environment of the city: the groundwater level in the city has dropped, the replenishment of the underground soil by rainwater has been blocked, and the growth of plants on the ground surface has been affected. The increase of PM2.5 particles in the air, the heavy rain caused serious road surface water, traffic jams, etc.; on the other hand, the runoff production and confluence time shortened, the rainwater washing capacity increased, and the runoff pollution load increased.
