The front and rear sides of the rainwater collection filter 4 are provided with slopes inclined toward the rainwater collection filter 4, ensuring that rainwater in the grass-planting ditch 3 enters the rainwater collection filter 4.
[0023] A non-woven fabric water filter layer 43 is provided on the surface of the rainwater outlet grate 2 44 to enhance the filtering performance.
[0024] A resin concrete shell 41 is provided on the outside of the rainwater collection filter 4 to resist compression.
[0025] The water guide system 5 includes a double-walled corrugated pipe 52 and a stainless steel wire mesh 51. One end of the double-walled corrugated pipe 52 is arranged inside the ceramsite adsorption layer 45, and the other end of the double-walled corrugated pipe 52 extends to the outside of the ceramsite adsorption layer 45. When in use, the outlet of the water guide system 5 is connected to the landscape water system pool 6, and the filtered and purified rainwater is introduced into the landscape water system pool 6 to supplement the landscape water system water. In addition, the outlet of the double-walled corrugated pipe 52 is controlled above the design water level of 6 to prevent water backflow.
