In the above embodiment, after the green plant layer 1 grows to completely cover the ground surface, the green plant layer 1 is low and dense, can have higher rainwater retention amount, and the net structure woven by the overground stems of the pennisetum alopecuroides can improve the surface runoff resistance, improve the water storage capacity of the green plant, prevent birds from gathering indirectly, and can reduce the bird strike safety problem.
When the green planting layer 1 is subjected to extreme weather such as heavy rain, a large amount of rainwater can be trapped by the blades and the overground stems of the green planting layer 1 and the large granular substrate of the adsorption layer 2, and the redundant rainwater quickly infiltrates into the turf soil of the water storage layer 4 through the seepage layer 3, so that the lawn ponding condition during a rainfall peak is reduced.
The accumulated water on the airport pavement can quickly flow into the water collecting tank 6 through the lawn longitudinal slope and the internal filtering ceramsite 601 flows into the water storage pipeline 7 through the filtering holes 602, so that the filtration of rainwater is realized, and the accumulated water on the pavement is avoided. When the water storage pipeline 7 is full of rainwater, the rainwater flows into the overflow pipeline 8 through the overflow holes 701 and finally flows into the artificial lake, so that the high drainage efficiency in extreme weather can be realized.
After rainfall, the water storage pipeline 7 is full of filtered rainwater, the filtered rainwater slowly infiltrates and irrigates the lawn through the circular seepage holes 702, the long-time slow irrigation of the lawn is directly completed underground by the rainwater, the water resource waste caused by surface irrigation water evaporation can be reduced, and the water resource can be reasonably utilized.
In the foregoing embodiments, the descriptions of the embodiments are emphasized, and in part, not described or illustrated in any particular embodiment, reference is made to the related descriptions of other embodiments.
