Problems solved by technology

For example, due to the impermeability of concrete and asphalt pavement, the mode of "city looking at the sea" often appears when there is a sudden heavy rain in the city, and because the rainwater cannot penetrate into the ground through the road surface, a large amount of rainwater is discharged from the municipal sewage pipe network, which increases the the load on the municipal drainage system
In addition, the imperviousness of this kind of road surface completely blocks the precious natural precipitation from the underlying soil and groundwater. Most of the precipitation is discharged into surface water sources such as rivers, lakes and seas through the urban drainage system pipe network, which seriously affects the effective use of rainwater; Coupled with the excessive extraction of urban groundwater, the urban groundwater level is getting lower and lower, forming a geological "funnel-shaped" groundwater level, causing the ground to drop

Abstract

The invention relates to a nano-reinforced water-permeable material, a water-permeable floor tile and a water-permeable pavement. The nano-reinforced water-permeable material comprises the following raw materials in parts by weight: 70-100 parts of aggregate, 6-10 parts of active molecular sieve powder, 8-15 parts of nano calcium carbonate, 5-8 parts of nano titanium dioxide, 2-4 parts of a defoaming agent, 5-8 parts of a water reducing agent, 40-60 parts of a high-strength toughening agent, 35-50 parts of a high-strength binder, and 4-8 parts of holmium oxide. According to the nano-reinforcedwater permeable material disclosed by the invention, through reasonable proportioning of all the components, the water permeable coefficient, compressive strength, breaking strength, wear resistanceand other properties of the obtained water permeable material are far superior to that of common water permeable materials.

Description

technical field [0001] The invention belongs to the technical field of water-permeable materials, and in particular relates to a nano-reinforced water-permeable material, a water-permeable floor tile and a water-permeable pavement. Background technique [0002] At present, the surface of the city is basically covered by water-blocking materials such as buildings and concrete, and the hardened ground has a great negative impact on the ecological environment of the city. For example, due to the impermeability of concrete and asphalt pavement, the mode of "city looking at the sea" often appears when there is a sudden heavy rain in the city, and because the rainwater cannot penetrate into the ground through the road surface, a large amount of rainwater is discharged from the municipal sewage pipe network, which increases the the load on the municipal drainage system. In addition, the imperviousness of this kind of road surface completely blocks the precious natural precipitatio...
