Problems solved by technology
[0004] The purpose of the present invention is to provide a rainwater retention and infiltration system based on the sponge city municipal engineering, which solves the existing problem that the flood disaster inside the city is often ignored in the current urban construction, and it is easy for the rainwater to fail after a sudden torrential rain in the city. The problem of sufficient discharge and retention, so that the problem of full utilization of urban rainfall cannot be realized

The invention relates to the technical field of sponge city municipal engineering, in particular to a rainwater retention and permeation system based on sponge city municipal engineering, which comprises a city regulation and storage pond, the input end of the city regulation and storage pond is connected with water channels, water injection nodes are mounted on the side walls of the water channels, and water channel branch control ponds are arranged between the water channels; the output end of the sewage pump is connected with an urban subsurface flow constructed wetland through a flood output pipeline, the output end of the first water pump is connected with a suburban ditch through a flood output pipeline, and the output end of the second water pump is connected with an urban water storage center through a flood output pipeline. Rainwater generated in a city can be collected and dispatched at the same time through the arranged city regulation and storage pool, so that the purpose of unified coordination and unified dispatching of stored water in the city can be achieved, the problem of flood disasters in the city can be solved as much as possible, meanwhile, the rainwater can be discharged into suburban ditches or reservoirs outside the city, and the urban environment is protected. Therefore, the flood disaster resistance of a city is improved.
Description
technical field [0001] The invention relates to the technical field of sponge city municipal engineering, in particular to a rainwater retention and infiltration system based on sponge city municipal engineering. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, seeps, and purifies water, and releases the stored water when needed. use. The construction of sponge cities should follow the principles of ecological priority, combine natural ways with artificial measures, and maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and waterlogging prevention, and promote the utilization of rainwater resources. and ecological environment protection. In the process of sponge city construction, the systematic nature of natural pre...
