Abstract

A water storage cellar greening system for a roadside in a sponge city and a method for using the same, the greening system comprises a rectangular groove, the rectangular groove is located in the road subgrade, the rectangular groove is arranged along the roadside, and the inside is filled with a matrix; Nuogan water storage cellar, as well as the capillary water suction irrigation system, water bearing pipe, riser pipe, branch pipe and ventilation pipe connected with the water storage cellar; the top and side of the water storage cellar are respectively provided with two ports, and one of the top ports is connected to the vertical port. The other interface is connected to the ventilation pipe; one of the interfaces on the side is connected to the branch pipe, the other interface is connected to the water bearing pipe, the upper end of the water bearing pipe is connected to the side drain, and the side drain is arranged on the curbs on both sides of the green belt. The invention saves, develops and utilizes rainwater resources without occupying the area of ​​landscaping, relieves the pressure of water resources demand and the contradiction between greening land, relieves the pressure of urban waterlogging in the rainy season, improves the urban ecological environment, is green and environmentally friendly, and builds an ecological sponge city , to promote 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...
