TECHNICAL FIELD

[0001] The utility model relates to a highway subgrade slope drainage structure and belongs to the technical field of road engineering construction. BACKGROUND

[0002] In highway construction, the drainage performance of the highway subgrade slope drainage structure is very important. If the highway subgrade drainage is not properly treated, it is easy to be blocked and waterlogged, leading to water seepage from the road surface to the subgrade, and further softening and damaging the subgrade, resulting in no foundation support under the subgrade and seriously affecting the service life of the highway.

[0003] However, the common drainage system at present is mainly a drainage ditch, and a grid plate is arranged on the drainage ditch to separate large-particle impurities, so as to avoid the blockage of the drainage ditch. This structure is simple in construction and low in cost, but the separation effect of the grid plate is limited, and many impurities still enter the drainage ditch. The drainage ditch is still easy to be blocked in the narrow and gentle section, the drainage effect is poor, and when there are leaves, paper, plastic waste and the like on the grid plate, the grid holes on the drainage ditch are easy to be blocked. The existing drainage system standard cannot meet the use requirement in the flood season.
