Stepped self-water-supply green city plan

Abstract

The invention provides a stepped self-water-supply green city plan. According to the stepped self-water-supply green city plan, a high-position water pond and a city primary area are designed, whereinthe city primary area is constructed on the slope with the gradient being smaller than 5%, the width direction of the city primary area is downward along the slope, and the length-to-width ratio of the city primary area is 1.5 or above; a main river channel from high to low is designed in the middle of the city primary area, and a landscape zone is designed on the main river channel; a water collecting river channel is designed at the edge of the high side of the city primary area, a flood discharge river channel is designed at the edge of the lower side of the city primary area, and the mainriver channel communicates the water collecting river channel with the flood discharge river channel; two or more rainwater storage ponds are designed on the flood discharge river channel. For the city plan, the stepped structure is adopted, the automatic storage of rainwater can be realized, the automatic water supply for cities can be realized by utilizing the height difference, and meanwhile,the greening function and water discharge capacity of the cities can be improved.

Description

technical field [0001] The invention relates to the field of urban planning, in particular to a stepped self-supplying green urban planning. Background technique [0002] A city is a large settlement formed by the agglomeration of non-agricultural industries and non-agricultural population. A densely populated area is called a city, which generally includes residential areas, industrial areas, and commercial areas and has administrative jurisdiction. The administrative jurisdiction function of a city may involve a wider area than itself, including residential areas, streets, hospitals, schools, public green spaces, office buildings, commercial stores, squares, parks and other public facilities. In the process of running a city, water is essential, whether it is residential water, industrial and commercial production water, and water for urban greening will consume a lot of water resources. The city's water intake can be from lakes and rivers, or from groundwater sources. ...

AI Technical Summary

Problems solved by technology

With the increase of city scale, the city's water consumption will also increase simultaneously, which will further aggravate the phenomenon of urban water shortage.

On the other hand, there will be no rainwater falling on the city, and the rainwater will fall on the city to form waste water, which is discharged through the sewer, and the drainage of the sewer is limited, so when the precipitation on the city surface is greater than the maximum instantaneous drainage of the sewer It will cause instantaneous flooding in the city and affect the normal operation of the city
