Embodiment 1

[0020] as attached figure 1 , 2 as shown in

[0021] To build a planting pond on a roof that has been waterproofed, the waterproof layer must have the ability to prevent plant roots from puncturing. The inner side of the pool wall of the planting pool must be waterproofed. Two sections of PVC water pipes 6 are pre-buried on the wall 1 of the planting pond apart from the height of 50mm at the bottom of the pond, namely, the bottom of the water pipe nozzle is 50mm apart from the bottom of the pond, and one of them is selected as the water inlet 61, and the other is then used as the water outlet 62. Water pipe two ends all expose pond wall 100mm long so that be connected with other pipelines, and the diameter of PVC water pipe 6 depends on the size of planting pond, and present embodiment adopts the PVC water pipe of 40mm specification. 5 coils of soft permeable pipes with a length slightly shorter than the perimeter of the planting pool and a specification of 50mm are placed ...

Embodiment 2

[0025] as attached image 3 , Figure 4 As shown in , in order to improve the quality of collected rainwater, the above-mentioned soft permeable pipe can be covered and buried with a filter material layer before laying and filling the water storage material layer. The filter material layer can be river sand, stone powder slag , fine pottery sand and other materials, in this embodiment, fine pottery sand is selected as the filter material layer. In this embodiment, the specification of the PVC water pipe in this embodiment is 75mm, the bottom edge of the nozzle is about 120mm from the bottom of the pool, the specification of the soft permeable pipe is 80mm, and the accumulation height of the filter material layer buried in the soft permeable pipe is 120mm. The thickness of the material layer is 120 mm, and the material of the water storage material layer is crushed and screened waste brick and tile particles; the thickness of the expanded perlite layer is 50 mm. In order to p...

Embodiment 3

[0028] as attached image 3 , Figure 4 As shown in , in order to improve the quality of collected rainwater, the above-mentioned soft permeable pipe can be covered and buried with a filter material layer before laying and filling the water storage material layer. The filter material layer can be river sand, stone powder slag , fine pottery sand and other materials, in this embodiment, river sand is selected as the filter material layer. In this embodiment, the specification of the PVC water pipe in this embodiment is 90mm, the bottom edge of the nozzle is about 200mm away from the bottom of the pool, the specification of the soft permeable pipe is 100mm, and the accumulation height of the filter material layer buried in the soft permeable pipe is 200mm. The thickness of the material layer is 200 mm, and the material of the water storage layer is ceramsite; the thickness of the expanded perlite layer is 60 mm. A non-woven fabric layer 9 is arranged between the expanded perli...

Abstract

The invention relates to a roof greening pond with convenience for rain collection and belongs to the auxiliary facility field of buildings, more particularly to a greening facility placed on the top of the building. The roof greening pond comprises pond walls and a planting pond enclosed by pond walls. The invention is characterized in that a flexible water-permeable pipe is placed at the bottom of the planting pond; a water-retention material layer, an expanded perlite layer and a planting soil layer are placed in sequence at the bottom of the planting pond; PVC water pipes used as water inlet and water outlet respectively are connected with the two ends of the flexible water-permeable pipe; the ports of the water inlet and water outlet are positioned on the pond wall 50-200 mm away from the ground; and the thickness of the water-retention material layer is equal to the altitude of the water outlet. The roof greening pond has the advantages of simple structure, no need of drainage and filtration equipment special for rain collection, long irrigation cycle, minimized consumption of irrigation water, and long-term stability in water demand for the greening pond.

Description

Technical field: [0001] The invention relates to a roof greening planting pool convenient for collecting rainwater, which belongs to the field of auxiliary setting of buildings, in particular to greening facilities set on the top of buildings. Background technique: [0002] At present, in order to beautify the environment and purify the air quality of the community, many buildings use roof greening technology to green the top of the building. The greening treatment of the roof is mainly to plant various green plants or flowers on the roof. The most common practice of roof greening is to build roof planting ponds. In order to save the watering water in the planting pond and prevent the rotten roots of the plants, storage and drainage devices are usually arranged in the planting pond. In the prior art, the special storage and drainage plastic tray for the planting pond realizes the storage and drainage function, but the rainwater collected by it is usually very limited and c...
