The invention discloses an airport multi-stage rainwater storage and drainage system and a setting method, the airport multi-stage rainwater storage and drainage system comprises an airport runway, an airport taxiway and a soil area, and an overflow well and a central drainage pipe are arranged in the soil area; at least two circles of storage and stagnation areas and a circle of gravel energy dissipation area are sequentially arranged above the soil area and between the overflow well and the airport runway and between the overflow well and the airport taxiway, and the heights of the two adjacent areas from the gravel energy dissipation area to the storage and stagnation areas are gradually reduced; a water baffle and an overflow pipe are arranged between every two adjacent circles of storage and stagnation areas, the water baffle is arranged on one side of the lower storage and stagnation area in every two adjacent storage and stagnation areas, and the top end of the water baffle is higher than the higher storage and stagnation area in every two adjacent storage and stagnation areas and the adjacent overflow pipe. The device is of a hidden type, the infiltration capacity of a soil area is improved while the blocking risk is reduced, the rainwater runoff peak flow and the total runoff amount are reduced, rainwater is drained in a peak shifting mode, the size and scale of an airport drainage system can be greatly reduced, and the airport construction cost is reduced.
本发明公开了一种机场多级雨水蓄滞排放系统及设置方法,包括机场跑道、机场滑行道和土质区域，土质区域内设置有溢流井及中央排水管；土质区域上方且置于溢流井至机场跑道、溢流井至机场滑行道之间依次设置有至少两圈蓄滞区和一圈碎石消能区，碎石消能区至蓄滞区中相邻两个区的高度逐渐减小；相邻两圈蓄滞区之间设置有挡水板和溢流管，挡水板置于两相邻蓄滞区中高度较低的一蓄滞区一侧且顶端高度高于相邻蓄滞区中高度较高的一蓄滞区和相邻溢流管的高度。其为隐藏式，在降低堵塞风险的同时提高土质区域的下渗能力，降低雨水径流峰值流量与径流总量，使得雨水错峰排水，会大幅度减少机场排水系统尺寸和规模，降低机场建设成本。
