Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as Figure 1-Figure 4 Shown, when the present invention is implemented, according to the following steps:
[0021] First the infiltration ring inner ring 19 of the slope infiltration ring 3 is vertically pressed into the soil for a small amount, and then the infiltration ring outer ring 20 is vertically pressed into the soil for a small amount with concentric circles.
[0022] Then the rain tube 2 is installed, the rain tube 2 is positioned above the slope infiltration ring 3, the rain tube 2 is placed on the rain tube support 17, and the rain tube support 17 adopts a support leg that is long on one side and short on the other, so that the rain tube 2 can Keep the horizontal state above the slope, and the evaporation cover 18 of the rain tube 2 covers the area between the rain tube 2 and the slope infiltration ring 3 to reduce wat...
