Water storage type urban garden green space system

Abstract

The invention provides a water storage type urban garden green space system, and relates to the technical field of green space construction. Drainage channels are arranged on the two sides of a greenspace system module respectively. Road edge stone is arranged outside the drainage channels. The green space system module comprises a planting layer, a filtering layer, a preliminary permeating layer, a quick permeating layer and a water storage layer which are sequentially arranged from top to bottom. The water storage layer is located below a local frost line. The longitudinal section of the filtering layer is in a circular arc shape. The bottom of the planting layer and the top of the preliminary permeating layer are both matched with the filtering layer. The longitudinal section of the water storage layer is in a W shape. The two ends of the lowest point of the bottom of the water storage layer are each provided with a drain outlet. Each drain outlet is provided with a drainage pipe.An electromagnetic switch is arranged on each drainage pipe. The tops of the drainage channels are higher than the top face of the planting layer, the portions, higher than the top face of the planting layer, of the side walls of the tops of the drainage channels are provided with filtering plates, and the bottoms of the drainage pipelines are communicated with the water storage layer. The systemis simple in pavement method, has a green space water storage function, can reduce flooded field drainage burdens of roads on the two sides of a green space, and has underground water supplementing and ecology purifying functions.

Description

technical field [0001] The invention relates to the technical field of green space construction, in particular to a water storage type urban garden green space system. Background technique [0002] With the continuous development of society, urban environmental problems are becoming more and more serious. In order to improve people's living environment and improve the functions of urban gardens and green spaces, many cities are actively building "sponge cities". The so-called "sponge city" is to build a scientific and reasonable urbanization layout based on the carrying capacity of resources and the environment, minimize interference and damage to nature, and realize natural accumulation, natural infiltration, and natural purification of rainwater. Let the city be like a sponge, absorbing water when it rains heavily, and "spit" out the absorbed water when it is dry. [0003] The ecological pavement of gardens and green spaces is an important part of the construction of "spo...

AI Technical Summary

Problems solved by technology

One is that the water cannot be discharged in time according to the actual water storage situation. At the same time, when the rainwater is too heavy, the existing green space water storage structure cannot seep slowly, and the rainwater cannot be discharged from the green space in time, which will easily cause rainwater to spread and aggravate the drainage of roads on both sides of the green space. burden
