However, with the increasingly deep mind of the green environmental protection concept and the increasingly mature intelligentized and networked technology, the new generation of architectural designers endow more functions and significance to architectural design.

The real estate industry at home and abroad develops for many years, newly built houses grow in multiples, commodity house cells develop from basic residential cells to higher large comprehensive cells, the trend that commodity houses gradually break away from 'just needed' is great, ordinary apartment type commodity houses cannot meet the living demands of people, and house purchasing becomes a choice of more people for continuously improving living environments.

The current building design shows a real green building. That is, developers set green plant planting areas on balconies of all floors to plant a large number of green plants, so that the whole building looks more green and environment-friendly, and the effect of locally improving the home environment can be achieved. However, the problem is how this part of the green plant should be managed to ensure its survival rate before the house is built up to the point where a person enters it; after a person lives in, how to reduce the management burden of the householder on the green plants and enable the green plants to continuously survive so as to achieve the effect of long-term survival.

For this reason, the person skilled in the art has conceived many solutions to this problem, for example, chinese utility model patent with application number CN202020405408.8 discloses a green building roof rainwater collecting system, which includes a roof, an annular drainage channel is provided at the edge of the roof, the bottom of the drainage channel is communicated with a water conduit for draining rainwater, a filtering screen is provided at the port of the water conduit close to the roof, and a purifying device is connected to the end of the water conduit far from the roof. The rainwater purification device is arranged to collect rainwater, waste of rainwater resources is reduced, and accordingly the utilization rate of the rainwater is improved.

The top retaining wall 12 is also provided with a drain pipe 7, and the water inlet end of the drain pipe 7 is positioned above the water supply pipe 4, so that the water is discharged from the drain pipe 7 when the rainwater is large and the water is stored more, and is directly discharged into a sewer.

Furthermore, the water inlet end of the water supply pipe 4 is higher than the plane of the roof plate 5 by at least 2cm, so that the water inlet of the water supply pipe 4 is prevented from being blocked by precipitation, and a part of accumulated water can be kept on the roof plate 5 to cool the roof in hot weather.

Examples

As shown in fig. 1, 2, and 3, the schematic diagrams are only structural schematic diagrams of the present technical solution, and are designed according to the number of floors in practical application, and the application of the present technical solution is not limited by the number of floors.

After the green environment-friendly building is constructed, developers plant all the balconies of the building in green for attracting house purchasers to see and purchase. Before the house is sold, a property manager is needed to maintain green plants on each floor, each building has a plurality of floors, and the workload is huge; if only depending on natural rainfall, the lower balcony is often shielded by the upper balcony, and the green plants cannot be sufficiently supplied with water; and after a resident lives in, part of residents carry out closed management on the balcony, although the green plants can be maintained manually, if the resident is not at home for a period of time, the green plants can die quickly.

Therefore, the inventor designs the technical scheme. When the rainy day comes, rainwater mainly descends on the roof, falls on the supporting plate 9, flows into the supporting plate 9 through the permeable holes 901 on the supporting plate 9 and the gap at the edge of the supporting plate 9, enters the first filtering layer 11, is precipitated and primarily filtered in the first filtering layer 11, is further filtered at the second filtering layer 6, then enters the water feeding pipe 4, and is conveyed to the greening area 1 of each layer of balcony through the water feeding pipe 4, so that the water supplementing and watering of green plants are realized. The outlet end of the water supply pipe 4 is connected with a branch pipe 3, the branch pipe can be designed into a water outlet with a water outlet valve, or a drip irrigation head is arranged to carry out drip irrigation on a green area, so as to ensure more long-acting water supply.

When the rainy season comes, the rainwater is too much, the water level is about to exceed the supporting plate 9, then the water flow is discharged from the drain pipe 7, the water outlet end of the drain pipe 7 is directly connected to a ground sewer, and the rainwater is directly discharged from the drain pipe 7 and then enters a sewer system to be discharged. Under any condition, the water level on the roof can be effectively controlled, and the condition that rainwater overflows the edge of the top retaining wall 12 can not occur. Meanwhile, the supporting plate 9 can be used for walking pedestrians and supporting other equipment needing to be installed in a building, and the surface of the supporting plate 9 is free of accumulated water under the common condition.

The above-mentioned embodiments are merely exemplary, so as to enable those skilled in the art to better understand the technical solution, and should not be construed as limiting the scope of the present invention, and all modifications and simple substitutions made according to the technical solution of the present invention fall within the scope of the present invention.
