Roof water storage greening structure

Abstract

The invention relates to the technical field of roof greening, and in particular relates to a roof water storage greening structure. The roof water storage greening structure comprises planting grooves which are formed in a roof and used for planting vegetation and a water storage tank, wherein the planting grooves are communicated with the bottom of the water storage tank. The roof water storage greening structure has the advantages that the planting grooves are arranged for preventing components at each layer of the planting grooves from following along with water when rainfall is great or excessive water is poured, so that rock soil in the planting grooves can not be loose or washed off; meanwhile, the bottoms of the planting grooves are communicated with the water storage tank, and the highest water level in the water storage tank is lower than a water storage layers in the planting grooves, so that the structure can effectively store water and also can prevent a root system of the vegetation from being soaked and rotten as the water in the planting grooves is excessive, and during drought, rainwater stored in the water storage tank can be absorbed and utilized by a plant root system.

Description

technical field [0001] The invention relates to the technical field of roof greening, in particular to a roof water storage greening structure. Background technique [0002] With the increase of my country's urban population, urban land is becoming increasingly scarce. Under the background of less and less land for greening on the ground in urban built-up areas and high cost of demolition and relocation, the use of green roofs is a good way to improve the urban living environment. Moreover, roof greening not only improves the urban living environment, but also improves the thermal insulation performance of the roof and purifies the air. In addition, as my country vigorously promotes the construction of sponge cities, roof greening is an important measure for rainwater infiltration and storage. [0003] However, the roof greening is more inconvenient to manage and maintain than the ground greening because the vegetation is planted on the roof surface. The soil moisture rete...

Problems solved by technology

[0005] The purpose of the present invention is to propose a roof water storage and greening structure, which can solve the problems of large manual irrigation workload and high maintenance cost of roof greening in the prior art

[0006] The purpose of the present invention is also to propose a roof water storage and greening structure, which can solve the problem in the prior art that when the rainfall is large, the soil and the fertilizer applied in the soil are washed away and enter the sewer pipe to pollute the urban water body
