Abstract

At present, geotextile-wrapped PVC drainage pipes with holes and filled with crushed stones (gravel) inside are the most commonly employed seepage ditch structure in most highway subgrade projects. This kind of structure has sound drainage effect in the early stage of utilization, but once the wrapped geotextile is damaged, this can easily cause the drainage pipe to be blocked or even the entire seepage ditch to fail. To improve the drainage life of the seepage ditch, this paper carried out a new type of seepage ditch structure test indoors for six months, and then compared the drainage performance of three types of drainage pipes, including the plastic blind ditch, hard permeable pipe, and perforated PVC pipe, under different seepage ditch filling structures. Additionally, the variation law of the seepage ditch's drainage performance of different pipe materials under different reversed filters and water pressure conditions was systematically studied. The results show that when the reversed filter is made of medium coarse sand, the drainage efficiency of several drainage pipes is slightly higher than that of using gravel as the reversed filter. Among the three types of drainage pipe, the plastic blind ditch has the optimal drainage effect in two types of seepage ditch structures, with the drainage efficiency more than twice that of perforated PVC pipes. The plastic blind ditch filled with medium coarse sand as a reversed filter in the seepage ditch structure can significantly improve the drainage efficiency of the seepage ditch.
