Drainage pavement structure of ultra-wide pavement and construction method of drainage pavement structure
The invention discloses a drainage pavement structure of an ultra-wide pavement and a construction method of the drainage pavement structure, and relates to the technical field of road engineering, the drainage pavement structure sequentially comprises a drainage upper surface layer, a drainage middle surface layer, a graded broken stone layer, a drainage vertical shaft and a transverse drainage pipe from top to bottom, and the drainage upper surface layer and the drainage middle surface layer are made of open graded asphalt mixture; the outer side of the graded broken stone layer is coated with a PVC groove, and the side part of the PVC groove is upwards contacted with the drainage middle surface layer; the multiple drainage vertical shafts are arranged at intervals in the advancing direction of the ultra-wide road surface, the drainage vertical shafts upwards penetrate out and communicate with the bottoms of the PVC grooves, drainage well covers are arranged at the communicating positions of the drainage vertical shafts and the bottoms of the PVC grooves, and the drainage vertical shafts downwards communicate with transverse drainage pipes. The transverse drainage pipes extend in the advancing direction perpendicular to the ultra-wide road surface and communicate with an edge road surface drainage system of the ultra-wide road surface. The drainage speed of road surface water can be increased, the thickness of a road surface water film is reduced, and the road surface driving safety in rainy days is improved.
本发明公开一种超宽路面的排水路面结构及其施工方法，涉及道路工程技术领域，排水路面结构从上到下依次为排水上面层、排水中面层、级配碎石层、排水竖井和横向排水管，其中：排水上面层和排水中面层采用开级配沥青混合料；级配碎石层外侧包覆有PVC槽，PVC槽的侧部向上接触排水中面层；排水竖井有多个，多个排水竖井沿着超宽路面的前进方向间隔排列，且排水竖井向上穿出并连通PVC槽底部，排水竖井与PVC槽底部的连通位置设有排水井盖，排水竖井向下连通横向排水管，横向排水管沿着垂直超宽路面的前进方向延伸并连通超宽路面的边部路面排水系统。本发明可以加速路表水的排出速度，减小路表水膜厚度，提高路面雨天行车安全。
