Water-permeable sidewalk on bridge and construction method thereof
The invention belongs to the technical field of urban bridges, and relates to an on-bridge water-permeable sidewalk and a construction method thereof.The on-bridge water-permeable sidewalk comprises an outer side curb and an inner side curb which are arranged on a bridge body, a pipe wrapping concrete layer and a longitudinal drainage ditch are arranged between the outer side curb and the inner side curb, and a bridge floor leveling layer and a bridge floor waterproof layer are arranged between the pipe wrapping concrete layer and the bridge body; a bridge crossing pipeline is arranged on the bridge floor waterproof layer and arranged in the pipe wrapping concrete layer, and the longitudinal drainage ditch is arranged between the pipe wrapping concrete layer and the inner side curb and communicated with a bridge floor drainage system through a drainage pipe. The tops of the longitudinal drainage ditches are covered with permeable grids, the top faces of the permeable grids are flush with the top face of the pipe wrapping concrete layer, and the surfaces of the pipe wrapping concrete layer and the surfaces of the permeable grids are completely covered with a non-woven geotextile inverted filter layer, a water seepage spring steel pipe layer, a permeable concrete leveling layer, a sand cushion layer and a permeable surface layer which are sequentially arranged. The pavement accumulated water drainage device can quickly drain the accumulated water on the sidewalk and keep consistent with the pavement of a connected road.
本发明属于城市桥梁技术领域，涉及一种桥上透水型人行道及其施工方法，包括设置在桥梁主体上的外侧、内侧路缘石，外侧、内侧路缘石之间设置包管混凝土层和纵向排水沟，包管混凝土层与桥梁主体之间设置有桥面调平层和桥面防水层，桥面防水层上设置过桥管线，过桥管线设置在包管混凝土层中，纵向排水沟设置在包管混凝土层与内侧路缘石之间，纵向排水沟通过排水管与桥面排水系统连通；纵向排水沟的顶部覆盖有透水格栅，透水格栅的顶面与包管混凝土层的顶面齐平，包管混凝土层和透水格栅的表面被依次设置的无纺土工布反滤层、渗水弹簧钢管层、透水混凝土整平层、砂垫层和透水面层完全覆盖。本发明能快速排出人行道积水，并与相接道路铺装保持一致。
