Detailed Description

Referring to fig. 1, the greening planting module 2 is sequentially provided with a water storage layer 15, a filtering membrane 16, a gravel layer 17, a planting medium layer 18 and a jute net 19 from bottom to top. The water storage layer 15 is used for storing redundant part of water when the rainfall of the primary rainstorm is too large, and when the weather is met with a small amount of rainfall, the water storage layer can slowly release the stored water, so that the water required by the growth of plants is supplemented; the filtering membrane 16 is used for filtering smaller impurities in rainwater, and the membrane can be purchased as a finished product and replaced periodically; the diameter of the gravel layer 17 is phi 5-phi 7, and the gravel layer is used for filtering impurities of coarse particles in roof rainwater; the planting medium layer 18 is a soil matrix for planting green plants; the jute mesh 19 is used to cover the top layer of the planting structure to prevent the plants from being blown away by strong wind during rooting.

The greening module 2 is hung above the slope surface of the sloping roof 1 through the baffle 3, the bottom of the greening module 2 is provided with the drain pipe 5, when the rainstorm amount is too large, the excessive moisture in the greening module 2 is rapidly discharged, the root of a plant is prevented from being dead due to waterlogging, the upper end of the drain pipe 5 is positioned at the lower segment of the planting medium layer 18 of the greening module 2, and the lower end of the drain pipe extends downwards out of the bottom surface of the greening module 2. A drainage ditch 6 of the sloping roof 1 is communicated with a rainwater collecting tank 7, the rainwater collecting tank 7 is connected with a watering pipe 9 provided with a watering opening 10 through a water outlet pipe 8, and the watering pipe 9 is embedded in the upper section of a planting medium layer 18 in a plurality of greening planting modules 2. The irrigation opening 10 is preferably located on the top surface of the irrigation tube 9. And a water pump 13 and a valve 14 are arranged on the water outlet pipe 8, the water pump 13 is used for pressurizing and pumping rainwater stored in the rainwater collecting tank 7 into the irrigation pipe 9, and the valve 14 is used for adjusting the irrigation water quantity.
