The present invention relates to a rooftop greening system of a building that can realize economic feasibility by reducing all management elements necessary for supplying landscaping water.

The ongoing urban development project along with the development of the industry is not only damaging the ecosystem environment by reducing the green space, but also causing minute weather changes due to the urban heat island. In addition, the impermeable layer such as asphalt, which is increased instead of the green space, prevents rainfall from penetrating into the basement, thereby increasing flood damage of the city during flooding, and also causing the water shortage problem during the rain when it is discharged as it is not penetrated. have. Recently, as a way to solve these problems, a technique has been proposed to create a green space by utilizing the rooftop space of the building in the city. For example, in Korean Patent Registration Nos. 314544, 332076 and 349557, it is possible to give the air purification and urban heat island prevention effect in the city, and to anticipate the flood prevention effect due to the increase of low water quantity and the delay of discharge of effluent. The structure and construction method of a rooftop greening system are disclosed.

However, the conventional rooftop greening systems as described above require high water pressure for supplying landscaping water necessary for greening because the greenery is located at the highest point of the building. Therefore, the pump must be installed separately for the supply of landscaping water, and there is a problem that the energy cost is excessively required according to the operation of the pump.

In addition, the landscape management is inconvenient in the greening management of the roof, and because a lot of manpower is required for the landscape management work, there is a problem that the economic efficiency is deteriorated. together,

In addition, the conventional rooftop greening system is insufficient in water treatment function, such as rainwater, which is discharged into the river through the rooftop greening system, or flows into the basement, together with nutrients such as nitrogen and phosphorus from the soil and fertilizer.

In addition, since water is automatically supplied to the soil layer through the moisture absorbing member by simply opening the valve through the control unit and supplying the landscape water through the control unit, there is a need to complexly install the landscape water pipe for supplying the landscape water to the soil layer. As a result, the installation environment is very clean and simple, and the installation cost is significantly reduced.

In addition, by installing a purification filter layer in the lower part of the soil layer, the pollutants contained in the rainwater is adsorbed, decomposed, and filtered through the purification filter layer to be purified, and then discharged to the stream, thereby causing secondary environmental pollution by the contaminated initial rainfall water. Can be prevented.

In addition, by installing a fixture for fixing the moisture absorbing member on the upper part of the purification filter layer, the fixing operation of the moisture absorbing member can be made very simple and fast, thereby improving the workability.

In addition, the water stored in the reservoir inside the bank, or the water leaked through the roof drain, is automatically purified through the purification filter layer to improve the water quality, so there is no need for a separate water treatment to improve the water quality, thereby reducing the cost of water treatment. The effect can be obtained.
