A kind of permeable stone with biological purification function and preparation method thereof

Abstract

The invention discloses a water-permeable gutter apron with a biological purification function and a preparation method of the water-permeable gutter apron with the biological purification function. A first groove which is used for accommodating a porous water-permeable brick is formed in the upper part of an outer frame from front to back, a water storage groove which is used for storing retained water is formed in the lower part of the outer frame, both the length and width of the water storage groove are smaller than those of the first groove, the width of the porous water-permeable brick is greater than that of the water storage groove, and the porous water-permeable brick is located above the water storage groove; two water through gutters are separately formed in a front side wall and a rear side wall of the bottom wall of the outer frame symmetrically, and the bottom wall height of each water through gutter is greater than that of the water storage groove; the porous water-permeable brick comprises a water-permeable surface layer, a fine-pore water-permeable layer, a coarse-pore water-permeable layer and a micropore water seepage layer, and the water-permeable surface layer, the fine-pore water-permeable layer, the coarse-pore water-permeable layer and the micropore water seepage layer are laid sequentially from top to bottom. The water-permeable gutter apron is laid at the two sides of a road and has a relatively good distributed absorption and purification action on pavement runoff and accumulated water, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a method for preparing permeable stone with biological purification function, belonging to the technical field of environmental protection. Background technique [0002] Sponge city is a new generation of urban rainwater management and construction methods. Specifically, it means that cities have good "elasticity" in adapting to environmental changes and dealing with natural disasters caused by rainwater. The combination of measures, under the premise of ensuring the safety of urban drainage and waterlogging, maximizes the accumulation, infiltration and purification of rainwater in the urban area, and promotes the utilization of rainwater resources and the protection of the ecological environment. In the construction of sponge city, the concept of low-impact development is emphasized, which can provide a burden reduction and supplement to the traditional drainage system, and maximize the digestion and absorption of the city its...
