[0001] The present invention relates to the technical field of riverside roadbeds, and in particular to a riverside roadbed structure for intelligent flood damage prevention and control. Background Art

[0002] The road subgrade is the basic part of the road structure. It is located below the pavement layer and is used to carry vehicle loads and disperse them into the foundation soil. It is the foundation of the entire road structure and directly affects the stability and service life of the road. In different environments, it is necessary to fully consider geological conditions, traffic volume, and climate and environmental factors, and select appropriate materials and construction processes based on actual conditions to ensure the stability, durability and safety of the roadbed.

[0003] When constructing the existing riverside roadbed, the flow of the river and flood damage must be taken into consideration. However, due to long-term erosion by water, the roadbed cannot be effectively drained, which causes cracks and collapse inside the roadbed after long-term use, resulting in road safety hazards.

[0004] Therefore, the present invention provides a riverside roadbed structure for intelligent flood control and prevention to solve the problems raised in the above-mentioned background technology. Summary of the invention
