With the acceleration of China’s urbanization and the growing demand for underground space
development, TBM, as a core equipment for tunnel construction, has seen its technological innovation and intellectual
property protection become focal points of industry competition. Based on case studies involving patent information
analysis, natural language processing, and knowledge graph construction, this paper systematically explores the
integration mechanisms of information construction, intellectual property layout, and knowledge management in
the TBM field. The research indicates that: (1) patent intelligence serves as a core basis for assessing technological
competition trends and planning research and development directions; (2) knowledge graph technology enables the
digital reconstruction of unstructured maintenance knowledge, supporting intelligent decision-making; and (3) the
patent layout of intelligent sensing technology highlights technological hotspots and gaps. Finally, a comprehensive
framework for intellectual property and knowledge management in TBMs, centered on the theme of “data-driven,
knowledge-integrated, intelligent application,” is proposed to provide theoretical references for technological
innovation and strategic planning in the industry.
