Detailed ways

Referring to FIG. 1 , the greening planting module 2 is provided with an aquifer layer 15 , a filter membrane 16 , a gravel layer 17 , a planting medium layer 18 and a jute net 19 sequentially from bottom to top. Among them, the aquifer 15 is used to store the excess water when the rainfall is too large in a rainstorm. When encountering a climate with less rain, the aquifer can slowly release the stored water, thereby supplementing the water required for plant growth; The filter membrane 16 is used to filter small impurities in the rainwater, and this membrane can be purchased as a finished product and replaced regularly; the gravel layer 17 has a gravel diameter of Φ5-Φ7, which is used to filter the coarse particles of impurities in the roof rainwater; the planting The medium layer 18 is the soil matrix for planting green plants; the jute net 19 is used to cover the top layer of the planting structure to prevent the plants from being blown away by strong winds during the rooting process.

The greening planting module 2 is suspended above the slope of the sloping roof 1 through the baffle 3, and the bottom of the greening planting module 2 is provided with a drainage pipe 5, which is quickly discharged into the greening planting module 2 when a heavy rainfall is too large. The excess water prevents the roots of plants from dying from waterlogging. The upper end of the drainage pipe 5 is located in the lower section of the planting medium layer 18 of the greening planting module 2 , and the lower end extends downward from the bottom surface of the greening planting module 2 . The drainage ditch 6 of the sloping roof 1 is connected to the rainwater collection tank 7, and the rainwater collection tank 7 is connected to the watering pipe 9 with the watering port 10 through the water outlet pipe 8, and the watering pipe 9 is embedded in a plurality of greening planting modules 2. The upper section of the planting medium layer 18. The pouring spout 10 is preferably located on the top surface of the pouring pipe 9 . The water outlet pipe 8 is provided with a water pump 13 and a valve 14. The water pump 13 is used to pressurize the rainwater stored in the rainwater collection tank 7 into the watering pipe 9, and the valve 14 is used to adjust the watering amount.

The sloping roof 1 has its own drainage ditch 6 for collecting roof rainwater. The drainage ditch 6 can be built-in or external. The specific installation location or structure is not limited here. This is the prior art and will not be described in detail. The connection between the drainage ditch 6 and the rainwater collection tank 7 is provided with a filter device, the filter device is a rainwater grate 12 filled with a gravel filter layer 11, and the rainwater collected by the drainage ditch 6 is filtered by the filter device to naturally flow through the entrainment on the way. The impurity flows into the rainwater collection tank 7 for storage.

The baffle 3 is preferably a trapezoidal structure with a small upper part and a large lower part, and the bottom is fixed on the slope to improve the stability. The baffle 3 is not only connected to the greening planting module 2 in the form of a buckle 4, but also can be The irrigation pipe 9 provides support.

When the one-time rainfall is too large, the rainwater in the greening planting mold 2 will be discharged from the drain pipe 5 after being saturated, fall into the slope of the sloping roof 1, and flow into the drainage ditch 6 through the natural drainage slope of the roof slope to be collected and filtered. The gravel filter layer 11 and the rainwater grate 12 of the device are filtered to remove impurities and then flow into the rainwater collection tank 7 for storage; when the greening planting module 2 needs to be watered, the valve 14 is opened, the water pump 13 is started, and the water of the rainwater collection tank 7 enters the watering by the outlet pipe 8 The pipe 9 is then introduced into the greening planting mold 2 through the watering port 10 to provide water for the planted plants. The length of the water inlet pipe 6 can be adjusted according to the size of the green planting module 2, and can be connected in sections by flanges, which is convenient for disassembly and maintenance.
