Abstract

The invention provides a flexible sensing strip packaging structure and monitoring method for large deformation monitoring in the deep part of a landslide. All electronic components are welded on the front side of a PCB circuit board, and a plurality of measuring unit modules are arranged at intervals in the extending direction of the window opening and wiring , the window-opening cable is electrically connected to the reverse side of the PCB circuit board of multiple measuring unit modules in turn to form a measuring unit cluster, the measuring unit cluster is arranged in parallel with the reinforced steel wire rope, and is packaged and formed by a silicone extrusion process to form a silicone encapsulation layer. The measuring unit cluster, The reinforced steel wire rope is encapsulated in the silicone encapsulation layer to form a flexible sensing strip, and the flexible sensing strip can be wound into a sensing strip reel. The beneficial effects of the technical solution proposed by the invention are: strengthening the integrity of the connection between the measurement unit modules, improving the connection strength, and thus improving the reliability of the flexible inclinometer. The flexible sensing strip can be wound into a sensing strip reel, which is easy to carry and transport, and can produce coupling deformation with the landslide body, which can meet the larger deformation monitoring requirements.

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...
