As shown in FIG. 1 , the greening rainwater outlet module is arranged at the greenfield rainwater outlet to form a terrain with high surroundings and low middle, so that water can gather near the rainwater outlet. Preferably, the shapes of the rainwater collection box 2 and the cover box 6 are both hexahedral, so as to facilitate installation and shaping. Preferably, the materials of the rainwater collection box 2 and the cover box 6 are resin, which are integrally formed by resin. This form does not require brick side ditch, and the construction is simple and labor costs are saved. Preferably, the depth of the rainwater collection box 2 is 800mm, the depth of the cover box 6 is 500mm, and the diameter of the permeable hole 9 is less than 20mm. The caliber of the rainwater collection box 2 is not less than 600 mm in length * 600 mm in width, and the caliber of the cover box 6 is slightly smaller than that of the rainwater collection box 2, so that the cover box 6 is nested in the rainwater collection box 2 within.

As shown in Figures 2 and 3, the inner diameter of the rainwater collection box 2 is greater than the outer diameter of the cover box 6, and the depth of the rainwater collection box 2 is greater than the depth of the cover box 6, ensuring that the The cover box 6 can be completely put into the rainwater collection box 2, and it is ensured that there is still some space in the lower part of the rainwater collection box 2 for storing water.

As shown in Figure 4, the upper edge of the cover box 6 is provided with a hanging groove structure 1, and the hanging groove structure 1 is similar to a curling, similar to a hook, and the upper edge of the cover box 6 is fixed by the hanging groove structure 1. Hanging on the upper edge of the rainwater collection box 2, by filling the inside of the cover box 6 with stones and soil, the structure is not only stable under the action of gravity, but also easy to install and maintain.

The ecological retention soil layer 8 is planted with plants, and the bottom plate of the cover box 6 is provided with a permeable hole 9, and a stone filter layer 5 is placed at the bottom, covered with a non-woven fabric layer 4, and the above requirements are good water permeability and meet the requirements of << The ecological retention soil layer 3 of the Urban Greening Engineering Construction Acceptance Code, the depth of the ecological retention soil layer 3 is not less than 300mm, and the greening varieties are selected from plants that are resistant to pollution and waterlogging. The greening rainwater module is not less than 600mm, and the thickness of the ecological retention soil layer 3 is not less than 300mm, which is convenient for the upper plants to be grouped and matched.

Preferably, the stone filter layer 5 has a thickness of 200 mm, the non-woven fabric layer 4 has a thickness of 2-2.5 mm, and the ecological retention soil layer 3 has a thickness greater than or equal to 300 mm. The particle size of the gravel in the stone filter layer 5 is greater than 22.4mm, which is greater than the aperture of the permeable hole 9, and must not contain clay and other impurities. Among them, the crushed stone does not need to be graded crushed stone, it only needs to have a large hydrophobic pore size, which is used for filtration and water permeability. The ecological retention soil layer 3 includes raw soil, peat soil and vermiculite, and the volume ratio of the raw soil, peat soil and vermiculite is 7:2:1. By setting the ecological retention soil layer 3, the filtration and adsorption of the soil can be used to temporarily store rainwater and then slowly infiltrate into the auxiliary stone layer to control the amount of rainwater.
