Rainwater garden for collection and recycling of rainwater

Abstract

The invention discloses a rainwater garden for collection and recycling of rainwater. The rainwater garden comprises a garden body, a pisolith layer, a non-woven fabric layer, a sandy soil layer, a clay layer, a water storage layer, overflow pipes, a connecting pipe, ecological rainwater ditches, ditch bottoms, slope segments, vegetation, yellow schist layers, coarse sand layers, composite layers,outer coating layers, drainage blind pipes, lower vertical pipe segments, upper vertical pipe segments, communicating holes, limiting blocks, top covers, support rods and sliding blocks. Through arrangement of the water storage layer in the garden body and the three overflow pipes and three ecological rainwater ditches in the water storage layer, the distance between the top of each overflow pipeand the bottom of the water storage layer is 20 cm, excessive water in the water storage layer can flow into the connecting pipe from the overflow pipes, the bottoms of the ecological rainwater ditches are also provided with the drainage blind pipes, and the drainage blind pipes and the connecting pipe are both connected with a municipal rainwater pipe network, so that not only is the rainwater collected and reused, but also waterlogging of a park is prevented. The rainwater garden has the advantage of rainwater recycling.

Description

technical field [0001] The invention relates to a rainwater garden, in particular to a rainwater garden for collecting and recycling rainwater, and belongs to the technical field of garden construction. Background technique [0002] In the modern urban landscape, natural approaches and artificial measures should be considered comprehensively in terms of water resource recycling. Under the premise of ensuring the safety of urban drainage and waterlogging, it is necessary to maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and the protection of the ecological environment. Coordinate the systematic nature of natural precipitation, surface water, and groundwater, coordinate water supply, drainage, and other aspects of water recycling, and consider its complexity and long-term nature. Therefore, the subject of rainwater collection and reuse came into being. Parks usually use rain gardens to r...
