Abstract

The invention discloses a water storage cellar greening system for a sponge city roadside and a use method. The greening system comprises a rectangular groove, wherein the rectangular groove is located in a roadbed, arranged along a roadside, and filled with a matrix; a plurality of water storage cellars are arranged along the rectangular groove; the system further comprises a capillary water irrigation system, a water bearing pipe, a stand pipe, a branch pipe and a breather pipe communicated with each water storage cellar; two interfaces are respectively formed in the top and sides of each water storage cellar; one of the interfaces in the top is connected with the corresponding stand pipe, and the other interface is connected with the corresponding breather pipe; one of the interfaces inthe sides is connected with the corresponding branch pipe, and the other interface is connected with the corresponding water bearing pipe; the upper end of each water bearing pipe is connected to a side leakage; the side leakages are arranged on curbs on both sides of a green belt. According to the water storage cellar greening system, rainwater resources are stored and developed without occupying landscaping land areas, thereby alleviating the contradiction between the pressure of water demand and land use for greening in a city, alleviating the urban flood pressure during rainy season and improving the urban ecological environment; the greening system is environmentally friendly, builds an ecological sponge city, and promotes the coordination of urban ecosystems.

Description

technical field [0001] The invention relates to the technical fields of sponge city, landscaping, energy conservation and environmental protection, and in particular to a water storage cellar greening system and maintenance method used for roadsides of the sponge city. Background technique [0002] As the process of urbanization continues to accelerate, the number of urban populations has increased sharply, and the demand for water has increased. Especially in the northern region, due to the excessive use of groundwater, many land subsidence problems have occurred from time to time, seriously affecting people's safety. There is also the improvement of various supporting infrastructure in the city, and the area of ​​various hard pavements has increased significantly. In the rainy season, especially in case of heavy rainfall that lasts for several days, urban areas with low terrain are prone to large areas of waterlogging, resulting in waterlogging, which greatly affects the w...
