1. Introduction
The 21st century is the era of sustainable development and high-quality development of underground space has become an international consensus. The integration technology of deep foundation pit and underground space engineering is an important trend of future development. The combination of building foundation and underground space development can improve land use efficiency. The construction technology of deep foundation pit includes underground continuous wall, reverse method and other ways, which can realize the comprehensive utilization of above ground and underground space. With the improvement of environmental awareness, the future deep foundation pit and underground space projects will pay more attention to environmental protection and energy saving, such as the use of green building materials, energy-saving construction technology, etc., to reduce the impact on the environment. At the same time, in order to improve construction efficiency and safety, the future deep foundation pit and underground space projects will pay more attention to the optimization of construction technology and the implementation of safety measures. With the acceleration of the urbanization process and the continuous advancement of infrastructure construction, the application field of deep foundation pit and underground space engineering technology will continue to expand, and scientific and technological innovation and research and development will be further strengthened in the future to promote the development of deep foundation pit construction equipment and technology to a higher level.
"2024 Foundation Pit Construction Technology and Equipment Exhibition", as an important exhibition direction of the theme of "Urban Safety and Lifeline" "Plate" underground space Engineering and technology "of this Expo, focuses on displaying advanced equipment and technology of construction and testing, green environmental protection materials, underground space detection technology and equipment, underground space reserve facilities construction and other contents. Covering the whole industry chain cycle from the upstream and downstream of the industry, such as design, construction, operation and maintenance management, urban safety and disaster prevention, 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.
