Ecological greening system of building

Abstract

The invention discloses an ecological greening system of a building, which comprises a water storage layer, a soil isolation layer, a nutrient soil layer and a greening plant planted on the nutrient soil layer in turn from the bottom to the top, wherein the water storage layer is closed; the soil isolation layer is provided with a plurality of through holes, and water absorption materials are filled in the through holes; one end of the water absorption material is positioned below the water level of the water storage layer, while the other end is dispersedly arranged on the lower part of the nutrient soil layer on the upper surface of the soil isolation layer along four sides; and a water inlet pipe connected with a tap water pipe of the building is arranged in the water storage layer, a water level control valve is arranged at the outlet of the water inlet pipe, a water outlet is also formed in the water storage layer, and the water outlet is higher than the controlled water level of the water level control valve. Compared with the prior art, due to extremely low implementation cost and maintenance cost, the ecological greening system of the building has the advantages of low cost and easy maintenance.

Description

technical field [0001] The invention relates to a gardening greening technology, in particular to a building ecological greening system which can be used for building greening. Background technique [0002] At present, with the acceleration of urban construction, the area left for urban greening is getting smaller and smaller. At the same time, with the acceleration of the urbanization process, the reduction of greening has caused catastrophic problems such as the global greenhouse effect. So at present, how to carry out urban greening, especially directly to the greening of buildings, has become a research focus of current people. [0003] In the prior art, in order to increase the greening area of ​​buildings, it is generally adopted to arrange roof gardens on the roof or utilize balconies to plant flowers and plants. This existing greening mode, because balcony or roof all does not belong to natural ecological environment, so all must artificially carry out watering mai...

AI Technical Summary

Problems solved by technology

In this existing greening method, because the balcony or the roof does not belong to the natural ecological environment, it is necessary to manually water and maintain the greening for a long time.

In this way, the cost of manual maintenance is too high and it is difficult to maintain

In the prior art, there is also a technology of using automatic sprinkler irrigation on the green land on the roof, which can save labor by automatically watering and maintaining the green land. High cost due to function

At the same time, most of the sprayed irrigation water will evaporate into the air, increasing the cost of water use

Therefore, these existing technologies are difficult to popularize and implement due to excessive cost.

Therefore, in the existing cities, most of the buildings, especially the roofs of buildings, have not yet taken greening measures.
