Analysis of the Key Points of Roadbed Drainage Design in the Reconstruction and Expansion of Rural Roads
Subgrade drainage design in the reconstruction and expansion of rural roads is a key link to ensure the stability and service life of roads.The design method mainly includes four aspects:the ground drainage method,un-derground drainage method,comprehensive drainage method and green drainage method,and each method has de-tailed design steps.The key points of subgrade drainage design are the reasonable layout of the drainage system,the functionality and durability of drainage facilities,coordination with the surrounding environment and the ability to cope with extreme weather and natural disasters.Only by comprehensively considering natural factors,engineering factors,material factors and other factors can we realize the efficient operation of the subgrade drainage system of ru-ral roads,so as to improve the service life and safety of roads.
