Application Of Sponge City In Jinan Urban Road Design

Sponge city construction is an important measure to improve urban environment and promote urbanization.At present,the total scale and capacity of Jinan's road network are on the low side,and the traffic bottlenecks in the road network significantly restrict the full play of the overall function of the road network.According to the guiding ideology of "Sponge City",the concept of low-impact development is implemented in the design of tourist routes.Combined with various measures such as infiltration,stagnation,storage,purification,utilization and drainage,the total amount of runoff,peak runoff and runoff pollution are controlled through infiltration,storage,regulation,transfer and pollution interception and purification of rainwater,so as to realize rainwater accumulation.Storage,infiltration and purification.Based on the analysis and collation of the existing research results of sponge city construction at home and abroad,the relationship between sponge city and road green space is discussed.It is concluded that the road construction concept of sponge city is mainly embodied in the main role of road construction design in rainwater infiltration,absorption,storage and purification.Combining with the current situation and conditions of road construction in Jinan,the construction technology of sponge city and the problems of water resources security and its influence on the surrounding areas in the construction of sponge city in Jinan,The demand and goal of Ji'nan city's sponge city road construction are discussed.Taking the sponge transformation in the western section of tourism road as a case study,the design system of road sponge city is analyzed from three aspects: design objective,design idea and layout.The analysis and the analysis of energy-saving effect of construction have been studied and evaluated.The evaluation of investment benefit and social benefit of the project shows that the completion of the project is conducive to strengthening the urban landscape,upgrading the urban grade and improving the urban investment environment,which has good economic and social benefits.The upgrading and transformation of Jinan's tourist road can not only improve the road network framework and break through the regional traffic bottleneck,but also build a series of production and living security facilities closely related to people's livelihood,such as rainwater,sewage,weak electricity,transportation,etc.It is also an important measure to improve the quality of life of the surrounding residents and enhance the image of the city.The reconstruction and construction of tourist road conforms to the development plan of Jinan municipal infrastructure construction,is conducive to speeding up the construction of urban infrastructure and improving the comprehensive service function of the city,and is an important manifestation of the concept of sponge city construction.The basic theory and practice system of sponge city construction of urban road green space formed in this paper can guide other road construction and regional construction of sponge city in Jinan scientifically and reasonably,help to improve the living standard of the surrounding residents,improve the urban outlook,and promote the sustainable development of the region and improve the external image of the city.It has a positive role in promoting.
