Research On Sunken Plaza In Sponge City System Of Cold Area

In recent years,urban water logging problems frequently occur in China,among them,the rapid expansion of cities,drainage system aging and other surface reasons,More importantly,under the guiding ideology of centralized collection and quick discharge of rainwater.Deal with rainwater problems beyond the drainage capacity of the pipeline,And "sponge city construction" put forward,to solve water logging problem provides new ideas and methods.Among them,the sunken square is one of the important components of the sponge city system,Its importance in solving urban water logging and improving the use of unconventional water resources are becoming more and more important.In addition,based on considering the cold city climate characteristics of the visible,cold sponge system of city sunken plaza is not only an important part of the sponge City,but also in winter and dry season around the venue people activities.Therefore,to understand the status of the cold sink type square sponge city system,city system analysis of cold sponge sunken plaza use demand and guide the future of cold sponge system of city sunken square design,with sunken plaza development of cold sponge in the city system of regional background,have a very important theoretical and realistic meaning.This paper expounds in detail the basic characteristics of sunken square and the classification of sunken square in sponge city system of cold area.First of all,according to the climate characteristics of the cold city,the overall planning and construction features of the sponge city and the characteristics of the sunken plaza,combined with the new changes of current rainwater storage policies and practices,put forward the ecological concept of the sunken square in the cold sponge city system and restore the benign hydrological cycle of the city,safety of urban water logging under heavy rainfall,increase the concept of water conservation for unconventional water resources and open public space for urban residents to carry out recreational activities.Influencing factors of sunken square design in sponge city system of cold area,summarized the design principle of sunken square in sponge city system of cold area: advocating the principle of ecology,highlighting the principles of regional culture and emphasizing the principles of human landscape.On this basis,this paper is based on the design principle of sunken square in sponge city system of cold area,from the field analysis,target determination,project design and performance analysis,combine successful design cases at home and abroad,then the design method of Sunken Plaza in sponge city system of cold area is summarized.First of all,realize the function of regulating and lowering the sunken square in the sponge city system of cold area;secondly,on the basis of satisfying the function,it has realized the role of providing entertainment and entertainment for the people as a landscape square.Finally,this paper takes the design of sunken square in the cold city sponge city system of Jilin Province as a practical case,summarizes the design method of sunken square which is suitable for the spongy city system in the cold area of North China.This paper studies the design of sunken square in sponge city system of cold area,which hope is to build a sunken plaza system in the cold place sponge city system,which promotes ecology,highlights regional culture and emphasizes the human landscape,realize the transition from theoretical layer to practical level.
