As the "lifeline" of a city, underground pipeline is the material basis for the city's survival and development, which is related to the sustainable, stable and healthy development of the city's economy. It is called the "blood vessel" and "nerve" of a city. Its safe and stable operation is of great significance for the healthy development of the city. There are some problems in the construction of urban underground pipelines in China, such as the serious shortage of scale and the low level of management. In recent years, the frequent occurrence of heavy rain and waterlogging, pipeline leakage and explosion, road collapse and other events not only directly affect the urban landscape, but also seriously hinder the normal play of urban functions, and bring adverse effects on people's daily life and production safety!
Underground pipelines involve many fields, such as water supply, drainage, gas, electricity, heating, communication, industry, etc. with the increase of urban population and the rapid development of economic and social activities, the importance of underground pipelines and many contradictions caused by the management system of block division are increasingly prominent. At present, the construction of underground pipelines lags behind, the disordered excavation of surface roads and other situations form a significant contrast with the surface construction of modern urbanization. Therefore, it is quite urgent to further strengthen the construction and management of underground pipelines.
In order to continue and better promote the sustainable development of underground pipeline construction and trenchless technology, improve the R & D, manufacturing and operation level of relevant products, and serve the construction and maintenance of national underground pipeline infrastructure, the 4th China (Shanghai) International trenchless technology and underground pipeline engineering exhibition 2018 will be held on May 25, 2018 with the strong support of competent departments at home and abroad Held in the National Convention and Exhibition Center from April 27! It will further expand the underground pipeline and trenchless related industrial chain, focus on displaying new technologies, new equipment, new products, new processes and new materials in the fields of trenchless technology and underground pipeline engineering, pipeline repair and detection at home and abroad. With the strong support of relevant government departments, it will join hands with many application industry associations to jointly create a broader market opportunity.

Nearly 300 industry cooperation media in more than 20 countries and regions in the world comprehensively promote and report the whole process, and enjoy the influence of brand exhibition
◆ exhibition highlights:
National group: it is displayed as a whole by associations and enterprises from developed countries and regions such as Germany, the United States, France, the United Kingdom, Canada, Australia and other important underground pipeline industries.  
Department support: the exhibition is strongly supported by many authoritative departments and guided by municipal management and non excavation construction competent departments, which will comprehensively improve the impact of the exhibition.  
Project docking: leaders of water supply, drainage, gas, heat, communication, power and other companies, pipeline planning, design departments, municipal companies and other departments will personally visit the exhibition site.
Summit Forum: at the same time of considering the academic level, it will strengthen the application of technology. During the exhibition, it will hold a number of deep-seated international academic conferences on Trenchless field and pipeline engineering. To achieve the combination of academic and practical; R & D and production; technology and industry.
