Abstract

The invention provides a landslide deep part large deformation monitoring flexible sensing strip packaging structure and a monitoring method, all electronic components are welded on a front surface of a PCB circuit board, and a plurality of measurement unit modules are arranged at intervals in the extension direction of a windowing flat cable. The windowing flat cable is sequentially and electrically connected with reverse sides of the PCBs of multiple measurement unit modules to form measurement unit clusters, the measurement unit clusters and the reinforced steel wire ropes are arranged in parallel and are packaged and formed through a silica gel extrusion processing technology to form a silica gel packaging layer, and the measurement unit clusters and the reinforced steel wire ropes are packaged in the silica gel packaging layer to form a flexible sensing strip. The flexible sensing strip may be wound into a sensing strip reel. The structure is advantaged in that integrity of connection between the measurement unit modules is enhanced, and the connection strength is improved, so reliability of the flexible inclinometry device is improved. The flexible sensing strip can be wound into a sensing strip reel, is convenient to carry and transport, can generate coupling deformation along with the landslide mass, and can meet the large deformation monitoring requirement.

Description

technical field [0001] The invention relates to the technical field of geological disaster monitoring and prevention, in particular to a flexible sensing strip packaging structure and monitoring method for large deformation monitoring in deep landslides. Background technique [0002] Landslide geological hazards have a wide distribution, serious hazards, and long duration, and seriously affect regional urbanization construction, railway traffic lines, and water resource utilization on a global scale. With the development of monitoring technology, professional geological disaster risk investigation, hidden danger investigation, and early identification combined with multiple technical categories have become an important way to scientifically and proactively prevent landslide geological disaster losses. Among them, deformation monitoring is the most direct and effective way in landslide geological disaster identification, early warning, decision-making and management. [0003...
