An ecological rain garden

Abstract

The invention relates to the technical field of city rainfall flood management, in particular to rainfall flood control and rainwater utilization facilities conforming to a sponge city concept, and specifically relates to an ecological type rainwater garden. The ecological type rainwater garden comprises a terrestrial landscape part, a pipeline system and a water ecosystem part, wherein the terrestrial landscape part comprises a horizontal pavement, a close-to-pavement lawn, a land lawn and terrestrial landscape plants; the pipeline system comprises vertical spraying pipes, an annular spraying pipe, a rainwater collecting pipeline, an electronic-control water pump and a water-return irrigation pipeline; the water ecosystem part comprises a water microbial community, an aquatic animal community and an aquatic plant community. The ecological type rainwater garden has the advantages that the ecological type rainwater garden uses the sponge city concept as the foundation, and perfect later maintenance management can be achieved; the ecological type rainwater garden can play an important role in urban inland inundation improvement, reclaimed water recycling, ecological environment protection and the like, and the construction of ecological and harmony city landscape ecological environments can be helped through a scientific and reasonable design concept.

Description

technical field [0001] The invention relates to the technical field of urban rainwater management, in particular to rainwater control and rainwater utilization facilities conforming to the concept of sponge city, in particular to an ecological rainwater garden. Background technique [0002] With the acceleration of urbanization, urban waterlogging disasters, water environment pollution and resource shortages also follow, so the concept of sponge city came into being. In the "2012 Low-Carbon City and Regional Development Science and Technology Forum" in April 2012, the concept of "sponge city" was first proposed. Sponge city is a new generation of urban stormwater management concept, which refers to the city's ability to adapt to environmental changes and respond to rainwater. It has good "elasticity" in natural disasters and other aspects. When it rains, it absorbs water, stores water, seeps water, purifies water, and "releases" the stored water and uses it when needed. The...
