Water storage and drainage ecological structure of environment-friendly roof

Abstract

The invention provides a water storage and drainage ecological structure of an environment-friendly roof, and belongs to the technical field of sponge cities. The water storage and drainage ecologicalstructure comprises a green roof structure, a water receiving bucket, a water guide pipe and the like, wherein the green roof structure is arranged on a roof plate of a house; in the structure of thegreen roof structure, a planting soil groove is formed in the upper part; a water storage cavity is formed in the lower part; a vegetation layer is arranged above the planting soil groove; a partition plate is arranged between the planting soil groove and the water storage cavity; the lower part of the water guide pipe communicates with an underground drainage pipe; and the water receiving bucketis arranged above the water guide pipe. The water storage and drainage ecological structure of the environment-friendly roof has the advantages that the defect that an existing roof needs to be frequently greened manually can be overcome through the operation of automatically filtering stored water, draining water and supplying water to vegetation, and the problems of rainwater resource waste, urban inland inundation and the like can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and in particular relates to a water storage and drainage ecological structure of an environmental protection roof. Background technique [0002] With the acceleration of urbanization, the area of ​​urban impermeable underlying surfaces (roofs, roads, squares, parking spaces, etc.) continues to expand, resulting in increased surface runoff and faster runoff speed. The rainfall retention capacity in urban areas has been greatly weakened, which has brought huge pressure to the urban drainage system, resulting in frequent floods in major cities in recent years, which have had a serious impact on people's lives, especially in the old cities that mostly use combined drainage systems. It also affects the stability of animal and plant habitats. As an important part of the urban impermeable underlying surface, the roof plays a very important role in the rainfall runoff, and occupies a relatively l...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides an ecological structure for water storage and drainage of an environmentally friendly roof, which can make full use of roof resources, significantly improve the utilization rate of the roof, and absorb rainwater when it rains, reducing rainstorm runoff. Solve the shortcomings of existing roofs that require frequent artificial greening through self-filtering water storage, drainage and water supply operations to vegetation, and can effectively solve problems such as waste of rainwater resources and urban waterlogging
