Problems solved by technology

[0003] In some early-designed internal transportation networks of green infrastructure such as sidewalks, community internal roads, and park green spaces, the roads are mostly non-permeable pavement or the drainage system of the permeable pavement is not perfect. After long-term use, the gaps will be blocked and the water permeability will be greatly reduced. In the rainy season, the road surface water cannot be removed in time to aggravate the urban waterlogging effect. If all these road surfaces are demolished and re-constructed into permeable road surfaces, the economic cost will increase

Abstract

The invention relates to a method for improving water permeability of a pavement.The method comprises the following steps: 1) removing a pavement surface layer; (2) performing drilling on a road base, wherein a hole channel downwards penetrates through the road base and the gravel layer in sequence and extends to the top of a plain soil layer; (3) cleaning the hole channel, laying inverted filter isolation cloth at the bottom of the hole channel, correspondingly covering opening of the hole channel with a reinforcing mesh, and fixing the reinforcing mesh; and 4) re-paving the pavement surface layer. The improvement method provided by the invention can be used for transforming a non-permeable pavement into a permeable pavement, and can also be used for repairing and improving the water permeability of an existing road pavement; and according to the paving modes of different road surfaces, the hole diameter of the drill hole, the hole channel filling treatment mode and the hole opening reinforcing measure can be selected, so that the bearing capacity of the pavement is guaranteed to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of urban water treatment, in particular to a method for improving the water permeability of road surfaces. Background technique [0002] Under the background of "sponge city" construction, the management and control of rainwater infiltration, stagnation, storage, purification, use and drainage are becoming more and more mature. Has broad development prospects. [0003] In some early-designed internal transportation networks of green infrastructure such as sidewalks, community internal roads, and park green spaces, the roads are mostly non-permeable pavement or the drainage system of the permeable pavement is not perfect. After long-term use, the gaps will be blocked and the water permeability will be greatly reduced. In the rainy season, the road surface water cannot be removed in time to aggravate the urban waterlogging effect. If all these road surfaces are demolished and re-constructed as permeable road ...
