Abstract

The present application relates to the technical field of road construction, and in particular to a semi-permeable road structure in a sponge city using the original road structure, which includes an original roadbed, and two sides of the original roadbed are provided with drainage and storage blind ditch, and drainage and storage blind ditch It is connected with a discharge pipe used to connect the urban underground drainage pipeline. There are standing edge stones on both sides of the original roadbed, and a first drainage outlet connecting the blind ditch for drainage and storage is opened on the standing edge stone. A waterproof mortar protective layer 1 is arranged between the roadbed and the original roadbed; a second drainage outlet is arranged between the permeable roadbed and the standing edge stone, the first drainage outlet is provided with a filter drainage piece 1, and the second drainage hole is arranged with a filter drainage piece 2. The first water outlet and the second water outlet are both connected to the drainage and storage blind ditch; a water collecting and guiding member is arranged in the permeable subgrade, and the water collecting and guiding member is connected to the drainage and storage blind ditch. The present application has the effect of reducing the damage of the original roads in the city, reducing the waterlogging problem of the urban roads and building a sponge city.

Description

technical field

[0001] The present application relates to the technical field of road construction, in particular to a semi-permeable road structure in a sponge city utilizing the original road structure. Background technique

[0002] Pavement is an important carrier of urban space and an important part of solving the problem of urban waterlogging. Semi-permeable structure road, also known as base impermeable structure road. It refers to the road structure system in which the surface water does not penetrate into the subgrade, and the accumulated water is discharged into the sides of the road or the municipal pipe network. The semi-permeable structure road is generally a combination of the base layer impermeable structure layer and the surface layer permeable structure layer. Practice has proved that semi-permeable structure roads can effectively balance the contradiction between water permeability and load requirements, and have good safety. They are widely used in urban ...
