AI Technical Summary
Existing football fields have slow drainage during rainfall and low water retention in the structural layer, resulting in surface water accumulation, which affects the permeability and aeration of the turf, and consequently impacts the turf's growth environment.
The perforated sponge pad adopts a three-layer structure, including high-density, medium-density and low-density sponge layers, with through holes between each layer. The surface of the high-density sponge layer is composited with a non-woven mesh, the medium-density layer is composited with a permeable geotextile, and the bottom of the low-density layer is composited with a permeable geotextile, forming a rapid drainage channel.
It enables rapid drainage of surface water during heavy rain, prevents damage to the sponge layer, improves the durability and efficiency of the drainage system, and maintains a healthy environment for lawn growth.
