Recently, in order to further understand the development of scientific and technological innovation in the industry and promote the application of new technologies, Liu Qianwei, Chief Engineer of the Shanghai Municipal Housing and Urban-Rural Development Commission, led a team to the construction site of Section 103 of the West Extension Project of Shanghai Rail Transit Line 13, to conduct an on-site investigation into the research, development and demonstration application of the actively controlled prefabricated mechanized caisson construction technology and the rail transit push-and-assemble synchronous intelligent shield tunneling technology.

　　At the investigation meeting, Tunnel Engineering Co., Ltd. of Shanghai Tunnel Engineering Co., Ltd. (Shanghai Tunnel Engineering Co., Ltd.) gave a detailed introduction, based on the actual progress of the construction site, to the development history, construction equipment, process flow and expanded application of the actively controlled prefabricated mechanized caisson construction technology, as well as the advantages of this technology such as safety and reliability, high efficiency and accuracy, and small environmental impact; it reported on the planning and progress of the rail transit push-and-assemble synchronous intelligent shield tunneling technology, introduced the application scenarios of the axis autonomous control technology that has already been put into use, and looked forward to new technologies under development such as shield autonomous driving technology, push-and-assemble synchronous technology, and automatic segment assembly technology.

　　Chief Engineer Liu Qianwei affirmed the achievements of Tunnel Engineering Co., Ltd. of Shanghai Tunnel Engineering Co., Ltd. in industry technological innovation, intelligent equipment research and development, and digital application, and pointed out that this technology has great demonstration application value in fields such as urban renewal and deep underground space development. At the same time, he put forward three requirements for future innovation work in the development of the underground space field: first, it is necessary to study and judge the frontier development trends of underground space and propose development directions and a list of major technologies; second, it is necessary to gather resources, build a scientific research platform for the development and utilization of underground space, give play to technological advantages, and effectively promote scientific and technological innovation work; third, it is necessary to focus on the transformation of achievements and demonstration applications, and, in conjunction with the **requirements and arrangements of the state on scientific and technological work, play a more important role in industry innovation work, enhance the industry's status, and form core competitiveness.
