Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a one-way permeable concrete structure and a preparation method thereof. Background technique [0002] With the continuous development of urban green ecological development and sponge city construction, the demand for permeable concrete projects is increasing. The existing sidewalk with fully permeable structure includes a base layer and a permeable concrete surface layer sequentially arranged on the roadbed, wherein the permeable concrete surface layer contains permeable holes. However, in the existing permeable pavement, because the permeable holes in the permeable concrete surface are easily blocked by garbage or dust, after a period of operation, the permeable function of the permeable structure will be lost, and rainwater will not be able to penetrate. Various tools are required to clean the permeable concrete pores on the pavement. Even so, it cannot effectively...
