Permeable paving system and paving method for removing oil stain in runoff rainwater

Abstract

The invention belongs to the technical field of permeable paving, and particularly discloses a permeable paving system and a paving method for removing oil stain in runoff rainwater. The permeable paving system structurally comprises a permeable layer, a leveling layer, a microorganism layer, a permeable geotextile layer and a permeable base layer from top to bottom. The permeable layer is used for quickly permeating the rainwater and primarily filtering the rainwater; the leveling layer is used for cushioning and permeating water; the microorganism layer is used for adsorbing and removing the oil stain in runoff, so that permeable channels can be prevented from being blocked by the oil stain, or the oil stain can be prevented from being permeated into underground water; the permeable geotextile layer is used for permeating the permeated water of the system and preventing loss of microorganisms; the permeable base layer is used for isolating natural soil from the permeable paving system and preventing the natural soil from being spread in the microorganism layer. The paving method includes excavating roadbeds; sequentially laying the permeable base layer, the permeable geotextile layer, the microorganism layer, the leveling layer and the permeable layer. The permeable paving system and the paving method have the advantages that the microorganisms can be regularly added into the permeable paving system, so that the content of the microorganisms can be guaranteed; the oil stain in the runoff rainwater can be effectively removed, the permeable paving system and the paving method are low-carbon, green and environmentally friendly and are wide in applicability, and energy can be saved.

Description

technical field

[0001] The invention belongs to the technical field of permeable pavement, and in particular relates to a permeable pavement system and a pavement method for removing oil stains in runoff rainwater. Background technique

[0002] In the process of urbanization, the surface of modern cities is gradually hardened and covered by water-blocking materials such as buildings and concrete, forming an ecological "artificial desert". While convenient transportation facilities and paved roads bring great convenience to people's travel, these impermeable roads also have a great negative impact on the ecological environment of the city. Therefore, in the construction of urban ground, it is necessary to follow the laws of nature, coordinate the city with nature as much as possible, achieve the combination of ground hardening and ground "softening", and strengthen the "softening" construction of urban ground while satisfying urban functions .
