Pavement drainage ditch and construction method thereof
The invention relates to the technical field of pavement drainage, in particular to a pavement drainage ditch and a construction method thereof. The pavement drainage ditch comprises a permeable surface layer, a permeable asphalt mixture layer, a water collecting pipe and a sealing layer, the permeable surface layer is flush with the upper surface layer of the original pavement structure; the permeable asphalt mixture layer is located on the lower side of the permeable surface layer, a sealing layer is arranged between the permeable asphalt mixture layer and an original pavement structure, the permeable asphalt mixture layer comprises an upper layer and a lower layer, the cross section of each of the upper layer and the lower layer is in a wide-end-up shape, and the lowest point is located in the middle of each layer and tends to descend in the drainage direction; the water collecting pipe is arranged on the interface of the upper layer and the lower layer and located at the lowest point of the upper layer, water permeable holes are formed in the water collecting pipe, and the water collecting pipe is in a descending trend in the drainage direction. The problems of thick water film and stagnant water of the road pavement caused by insufficient transverse drainage capacity of the road pavement in rainy days are solved.
本发明涉及路面排水技术领域，尤其涉及一种路面排水沟及其施工方法。路面排水沟包括：透水面层、透水沥青混合料层、集水管以及封层；所述透水面层与原路面结构上面层齐平；所述透水沥青混合料层位于所述透水面层的下侧，与原路面结构之间设置封层，透水沥青混合料层包括上层和下层，上层和下层的横截面均呈上宽下窄形状，且最低点位于每层的中部，最低点沿排水方向呈下降趋势；所述集水管布置在所述上层和下层的交界面上，且位于上层的最低点，集水管设置有透水孔，集水管沿排水方向呈下降趋势。通过本发明解决了雨天公路路面横向排水能力不足导致路段路面水膜厚、滞水的问题。
