However, flood control and drainage are the only focuses, and the rest functions of water course are slighted. Besides, cross-section biodiversity is falling and wetland self-cleaning capacity is impairing, resulting from river limitation on riverbed, making a straight river bend and revetment. So, water course has to be managed from ecology, economy, culture and social effect, to re- store natural river function and meet human demands. And to return to nature and people first would be the general principles.展开更多

In this context, the concept of "sponge city" is proposed. This paper, based on the theory of sponge city and low impact development, elaborated the origin, development, connotation, and construction method of "sponge city" concept. In this paper, the urban design scheme of Renbei District in Chengdu was taken for example to analyze the geographical environment and climate characteristics of Chengdu and explain the formation and verification of the scheme. It is considered that the "sponge city" is different from the traditional urban infrastructure. It is essentially an ecological approach. Its core is to build a cross-scale urban water ecological infrastructure to comprehensively solve the prominent water-related problems of urban and rural areas in China.展开更多

In 2015, the pilot city of sponge city's construction has begun to take shape with the push of the Ministry of Housing and Urban-Rural Development of the Peoples' Republic of China, the Ministry of Finance and the Ministry of Water Resources. For the pilot cities, they should strengthen the performance evaluation process and play the leading role of the nation demonstration. Taking the aspects of sponge city project's management, runoff volume control into consideration, sponge city initially formed a set of scientific and objective evaluation index which is in order to reflect the effectiveness of Gui-An New Area's construction.What's more, through analyzing the sponge city's deficiency of the performance evaluation, I also carry out the work that need to put forward suggestions.展开更多

Especially in the rainy season in July and August, the flooding problem in the city has been highlighted, which has brought potential safety hazards, not only threatening the safety of residents' lives, but also damaging the ranks of roads and bridges and reducing the service life of roads and bridges. In order to adapt to the construction concept of "Sponge City" and improve the design and construction level of local roads and bridges, relevant design knowledge must be used in the design and research of urban roads and bridges. The roads and bridges in the city have a lot of urban space. By doing a good job in the construction and design of roads and bridges, urban environmental problems can be effectively improved. In order to carry out the construction and design of roads and bridges, the concept of sponge city can be used to improve the urban environment and meet the need of optimal allocation of water resources. Therefore, in order to meet the needs of urban ecosystem construction, the systematic design of roads and bridges should be strengthened.展开更多

In order to improve urban construction, we must actively integrate the concept of sponge city into urban construction, design urban water supply in sponge mode, and effectively reduce the shortage of urban water resources through effective rainwater treatment. Reducing the occurrence of flood is also an inevitable trend of modern urban construction. This paper mainly analyzes the application of sponge city concept in municipal road water supply and drainage engineering design, introduces the concept and present situation of sponge city, studies the advantages of sponge city, and puts forward the implementation countermeasures, hoping to provide reference for relevant designers.展开更多

Sponge city regards the city as a huge sponge to absorb water. The city needs to play the functions of water storage, water collection and circulating water. In layman's terms, the idea of sponge city is to make the city look like a sponge. In case of heavy rain, rainwater can be well infiltrated, maintained and stored, and the remaining rainwater can be purified and used for final useful applications. In such cities, the destructive power of heavy rain is greatly reduced, but water resources can be well compensated. Sponge city has formed a new urban concept, become an improvement project of municipal optimization, and is the driving force of municipal water supply and drainage reform in the future. Next, the article discusses the application of sponge city concept in municipal water supply and drainage design.展开更多

Nowadays, "Sponge City" has become the focus of the planning and design of urban residential areas. Through the investigation and evaluation of several residential sponge projects, it is found that the landscape effect of sponge facilities cant meet the aesthetic needs of residents, besides its own function of regulating and storing rainwater. Therefore, improving the landscape effect of sponge cities in residential areas is the main direction of later sponge city construction. This paper summarizes the obstacles encountered in the application of sponge city concept in civil architecture design, and finally puts forward relevant measures, hoping to provide valuable reference for relevant designers.展开更多

Water on the road has caused serious traffic congestion and travel inconvenience, seriously affected peoples daily activities, and caused great environmental damage and loss of life and property. Traditional drainage facilities have been unable to completely solve the problem of urban waterlogging. The construction of sponge cities should be combined to ease the pressure of urban rainwater drainage. LID measures should be used to improve the water permeability of the underlying surface, reduce the comprehensive runoff coefficient, increase the storage capacity, and prevent natural disasters.展开更多

However, in the actual application process, due to various reasons, the concept of sponge city has not been well applied, which makes the rainwater resources in the city unable to be purified and stored, especially in the dry season. Therefore, only by studying the concept of sponge city can we avoid the occurrence of heat island phenomenon and play a better role in beautifying the urban environment.展开更多

Through the comprehensive and reasonable planning of the water supply pipe network, it can effectively solve the problem of urban water accumulation, and make it in the real sense of "sponge". In the design, it is necessary to combine the original water supply and drainage and geomorphic geology, comprehensively use the concept of sponge city, strictly control the materials, structure and other details, so as to ensure the reliability and rationality of the water supply and drainage system, and provide a good urban environment for citizens.展开更多
