Urban emergency rainwater drainage system

Abstract

The invention relates to an urban emergency rainwater drainage system, comprising drain wells, rainwater wells and a sewage discharge pipeline, wherein the rainwater wells are respectively connected with rainwater collection wells and are separately connected with a drainage ditch; the tail end of the sewage discharge pipeline is communicated with a sewage treatment terminal; the urban emergency rainwater drainage system is characterized in that each drain well is internally provided with an upper layer of one-way reverse osmosis prevention device and a lower layer of one-way reverse osmosis prevention device, and each rainwater well is internally provided with an upper layer of one-way reverse osmosis prevention device and a lower layer of one-way reverse osmosis prevention device; all the drain wells are connected in series or in parallel on the sewage discharge pipeline; a main treatment pipeline is communicated with all the rainwater wells, and all the rainwater wells are respectively communicated with the at least one drain well by a communicating pipeline; inlet ends of the communicating pipelines are communicated with the rainwater wells, and inlets of the communicating pipelines are respectively formed between the two layers of one-way reverse osmosis prevention devices on the walls of the rainwater wells; outlet ends of the communicating pipelines are communicated with the drain wells, outlets of the communicating pipelines are respectively formed between the two layers of one-way reverse osmosis prevention devices on the walls of the drain wells, and one-way communicating vessels are respectively installed at the outlets of the communicating pipelines. The urban emergency rainwater drainage system is simple in structure, compact in design, simple and convenient in construction, energy-saving and environment-friendly, and can effectively solve the problem of rain deposition while effectively utilizing the available resources.

Description

technical field [0001] The invention and an urban rainwater emergency drainage system belong to the technical field of municipal pipe network facilities. Background technique [0002] With the rapid development of modern cities, the rapid increase of cement, asphalt ground and various large buildings in the city has greatly reduced the self-drainage function of the city, and the commonly used rainwater drainage system is often unable to cope with sudden sudden precipitation and Long-term precipitation during the rainy season, and if the entire urban rainwater drainage system is expanded, the cost and maintenance cost will be high, and the frequency of use will be low. At the same time, due to the large construction area and long cycle, it will bring great inconvenience to the production and life of the entire city. . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an urban rainwater emer...
