Problems solved by technology

[0003] (1) The road surface is impermeable, and the replenishment of groundwater by rainwater is blocked, making it difficult for the city's groundwater level to rise;
[0004] (2) Surface runoff is likely to be generated during the rainy season, and a large amount of urban pollutants will be directly discharged into local rivers through pipelines together with rainwater, causing secondary pollution;
[0008] 1. Under the condition of satisfying the water permeability coefficient, the compressive strength of domestic permeable concrete pavements is generally lower than 30.0MPa, and the flexural strength is used on light-loaded pavements such as sidewalks, landscape roads, parking lots, etc., and is rarely used in heavy-loaded pavements
[0009] 2. After the construction of the permeable concrete project, there will be stones falling soon, which will seriously affect the service life of the road
For example, although the organic cementing agent has a good reinforcing effect, the cost is high, and the durability of permeable concrete is caused by poor alkali resistance; ordinary inorganic cementing agents have poor reinforcing effect, which seriously affects the product quality in the construction of thick concrete.

Description

technical field [0001] The invention belongs to the field of permeable concrete additives, and in particular relates to a high-performance permeable concrete water-based liquid reinforcing material and a preparation method thereof. Background technique [0002] The hardened ground design of traditional urban roads and squares mainly focuses on its durability and other technical performance indicators and visual aesthetic requirements, so a large number of non-permeable pavements are used. However, this pavement method has obvious ecological and environmental defects. Have: [0003] (1) The road surface is impermeable, and the replenishment of groundwater by rainwater is blocked, making it difficult for the city's groundwater level to rise; [0004] (2) Surface runoff is likely to be generated during the rainy season, and a large amount of urban pollutants will be directly discharged into local rivers through pipelines together with rainwater, causing secondary pollution; ...
