  • Publication number: 20250095177
    Abstract: A method and a system for automatically collecting multiple information of a tunnel during construction period are provided. A detection point and a detection line are formed by projecting a light source on the inner wall of the tunnel, and then the pixel position changes of the areas where the detection point and the detection line are located in different time periods are recorded by a measuring camera, and the detection point and the detection line are integrated and corrected with tunnel point cloud data as a reference standard to form an accurate four-dimensional model of the tunnel.

  • Patent number: 12169523
    Abstract: The present disclosure provides method and apparatus for query conversion. A first query for a first graph database may be obtained. A syntax tree may be generated through parsing the first query. A query graph may be created based on the syntax tree. The query graph may be converted into a second query for a second graph database.

  • Patent number: 11808152
    Abstract: A method for real-time strength estimation, grading, and early warning of rock mass in tunnel boring machine (TBM) tunneling, and belongs to the technical field of TBM tunnel construction. The method includes the following steps: establishing a general relation model of equivalent strength Rec of the TBM boring rock mass and a field penetration index (FPI); and applying the model to TBM boring construction, estimating an integrity coefficient Kv of the TBM boring rock mass in real time according to boring parameters acquired by a TBM in real time, and performing grading and early warning on the TBM boring rock mass according to a given grading standard and early warning values.
