Description

Technical Field

[0001] The utility model relates to the technical field of subgrade and pavement drainage, and particularly relates to a drainage structure for subgrade and pavement to prevent waterlogging. Background Technique

[0002] The subgrade is the foundation of the track or pavement, and is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of the track or pavement and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and rolling stock or the pavement and traffic loads, and at the same time transfer and disperse the loads deep into the foundation. Drainage structures are installed in the existing subgrade and pavement to drain the water source on the surface of the subgrade.

[0003] However, the existing drainage structure for subgrade and pavement to prevent waterlogging has the following disadvantages:

[0004] (1) For the existing drainage structure for subgrade and pavement to prevent waterlogging, the function of solid-liquid separation is weak. When in use, during rain, rainwater will wash small impurities on the road surface and flow to one side together. During the drainage process, the accumulation of a large amount of small impurities will affect the drainage effect and subsequent water treatment processing, resulting in the blockage of the drainage outlet.

[0005] (2) For the existing drainage structure for subgrade and pavement to prevent waterlogging, the function of filtering large impurities is weak. When in use, a large rainfall will wash large sundries such as branches and garbage, and the large sundries will block the water inlet, resulting in the situation of unable to drain water.
