Abstract
In recent years, the concept of sponge city has been applied in different places. There are also many experts on sponge cities who believe that to build a sponge city in the city, we need to improve and optimize the rainwater system. In this way, we can better explore the way to plan and design the stormwater system when conducting the construction of the sponge city. This paper will also analyze and study the characteristics and functions of rainwater system planning in the construction of sponge city, and also point out the difficulties of the city in the construction of sponge city. Nowadays, the city must make clear its optimization direction, methods and principles in the transformation of rainwater system, and the optimization and transformation of rainwater system can also improve the construction progress of sponge city faster. The optimization and application of rainwater system can lay a solid foundation for the construction of sponge city.
Highlights
With the rapid development of Chinese urbanization, the drainage pressure of rainwater pipes in previous cities is gradually increasing
This paper will plan and optimize the rainwater system according to the way of creating a sponge city
China 's urbanization will account for more than half of the country' s land, and the continuous expansion of urbanization will make many green ecological land occupied by urban land
Summary
With the rapid development of Chinese urbanization, the drainage pressure of rainwater pipes in previous cities is gradually increasing. The original drainage system has been aging, which can no longer play the role of relieving rain drainage, which makes waterlogging often occur in cities. The original intention of building a sponge city is to reduce the frequency of waterlogging in the city and to promote the development of the city. The state 's urban construction department started early on the planning to create a sponge city, and made many requirements and suggestions on the city' s rainwater system. This paper will plan and optimize the rainwater system according to the way of creating a sponge city
