Problems solved by technology

However, due to the large amount of suspended particles (such as silt, debris, etc.) contained in the surface runoff generated by rainfall, these mineral or organic fine particles will continue to enter the pores of the permeable pavement with the water flow, causing the pores to be blocked and the permeability of the permeable concrete to decrease continuously, resulting in It is difficult for permeable pavement to perform its drainage function, and eventually it evolves into a non-permeable pavement, which shortens its service life and increases the possibility of urban flooding and freeze-thaw disasters
[0003] At the same time, due to the large amount of rain and snow in winter in northern my country, the pavement bricks contain more pores. In the case of repeated freezing and thawing in winter, the strength of the pavement bricks will be reduced or even damaged.

Abstract

The invention relates to a plugging-resistant freeze-resistant pervious concrete pavement brick. The plugging-resistant freeze-resistant pervious concrete pavement brick mainly comprises a plugging-resistant surface layer and a base layer, wherein the plugging-resistant surface layer is positioned on the base layer and consists of the following materials components in a compounding ratio and in parts by weight: 80-100 parts of cement, 310-360 parts of coarse sand, 7-11 parts of silica fume, 6-10 parts of VAE emulsion, 25-35 parts of water and 0.8-1.2 parts of a water reducing agent; the base layer consists of the following material components in the compounding ratio and in parts by weight: 90-110 parts of cement, 220-260 parts of pebbles, 70-110 parts of coarse sand, 8-12 parts of silica fume, 8-12 parts of VAE emulsion, 0.1-0.4 of polyethylene fibers, 25-35 parts of water and 0.8-1.2 parts of a water reducing agent. New material components are designed, so that the concrete brick provided by the invention has good pervious freeze-thaw resistant effects and is not easy to plug.

Description

technical field [0001] The invention relates to the technical field related to civil engineering, in particular to an anti-clogging, frost-resistant and permeable concrete pavement brick and a manufacturing method thereof. Background technique [0002] Permeable paving bricks originated in the Netherlands and have been applied in the United States and Japan at the same time. There are a large number of penetrating pores inside the coarse aggregate skeleton of the pavement brick, which makes the pavement have good water permeability, and can quickly allow a large amount of rainwater to seep into the ground, thereby effectively reducing or eliminating urban rainstorm and flood disasters. However, due to the large amount of suspended particles (such as silt, debris, etc.) contained in the surface runoff generated by rainfall, these mineral or organic fine particles will continue to enter the pores of the permeable pavement with the water flow, causing the pores to be blocked an...
