1.Introduction

The 21st century is the era of sustainable development and high-quality development of underground space has become an international consensus. With the acceleration of urbanization in our country, the amount of urban underground pipeline expansion and reconstruction is increasing. Because trenchless construction has the advantages of low impact on road traffic and surrounding environment and high construction efficiency, it has been widely used in urban underground pipeline reform and expansion projects abroad, and has also begun to be used in some domestic cities. The main development direction of pipeline renewal technology in the future is to study how to carry out stable and reliable pipeline renewal without interrupting flow, and at the same time ensure the adaptability to complex working conditions in bustling urban areas, so as to further improve the efficiency of pipeline renewal.
"2024 Trenchless Technology and Equipment Exhibition" is an important exhibition direction of the theme of "Urban Safety and Lifeline" "Plate in" Underground Space Engineering and Technology "of this Expo. The exhibition focuses on the advanced equipment, green environmental protection materials, integrated pipe galleries and pipelines, underground space detection technology and equipment, underground space storage facilities construction and other contents of urban underground space planning and design, construction and construction, operation and maintenance management, urban safety and disaster prevention and other whole industry chain cycle, covering the upstream and downstream of the industry. Focusing on the upgrading of four new technologies in the underground space industry. The exhibition links all parts of the Yangtze River Delta to exchange and share practical experience and design inspiration in the development process of underground space, providing reference experience for the construction of low-carbon and resilient cities, providing theoretical basis for the rational planning and development of underground space development and utilization, and jointly promoting the further improvement and development of urban underground space development and utilization.
