Abstract： In the development of urban deep underground space，ultra-deep underground continuous walls have become the core supporting structure of major projects.However，complex geological environments constitute a construction botleneck，and existing technologies lack sufficient adaptability.Combined with the practice of an underground transportation hub supporting project，this paper constructs acollaborative technical system for trenching construction in complex geological conditions，focusing on three dimensions： equipment selection and adaptation， mud system regulation，and precisionand stabilitycontrol.Practice has shown thatthis technologycaneffectively prevent and control riskssuchas trench collapse and diameter reduction，ensure groove formation precisionand efficiency，and provide a reliable technical reference for similar projects.
