Abstract

The invention relates to a water-harvesting type roof rainwater garden. The water-harvesting type roof rainwater garden comprises an outdoor greening system and a rainwater circulating system, wherein the outdoor greening system comprises a roof vegetation layer, a sandy soil layer, a grit layer, a geotechnical cloth layer, a crushed stone cushion layer, a gravel layer, a barrier layer, a secondary filter layer and a rammed earth layer from top to bottom; the rainwater circulating system comprises a water storage tank, a water purifier, a water pump, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a soil humidity sensor, a first pipeline, a second pipeline, a third pipeline, a fourth pipeline and a PLC (programmable logic controller). According to the water-harvesting type roof rainwater garden, the problem about drainage and filtration of rainwater are solved, a graceful landscape environment space is created, and the rainwater is collected, purified and recycled perfectly.

Description

technical field [0001] The invention relates to a rainwater garden, in particular to a rainwater collection type roof rainwater garden. Background technique [0002] The scale of modern urban development is increasing, and the impact on ecology is becoming increasingly prominent. The emergence of a large amount of hardened land not only occupies the original water conservation land, but also changes the original natural ecological background and hydrological characteristics, destroying the natural "sponge". body", which has brought about a series of problems such as deterioration of urban water ecology, shortage of water resources, pollution of water environment, and lack of water security. The rain garden is a new ecological environment model that emerged from the times. Its appearance protects the hydrological status of the development area and also caters to the landscape needs of modern people. At the same time, rain gardens can also absorb and collect rainwater, conse...
