Displacement detection structure of slope failure detection device

摘要

(57) Abstract Objective The slope failure which uses the post, the column, and the optical fiberImprovement of displacement detection structure of detection device. Constitution Paralleling the multiple posts and, to this, the column which is laid andMaking use with of the optical fiber, displacement is raw relatively between the post and the columnThe ji optical fiber receiving deformation, output light being attenuated inspectionKnowledge doing, regarding to the device which detects the generation of slope failure, displacement inspectionOut the U shape of character metallic parts which the cut were opened in the both sides arm as a structure,In order for the said cut to be piled up to the both of the post and the column, to lock, thisSlope failure happening to the cut through the optical fiber, beforeWhen relative displacement of predicate occurs, it is due to bend in the optical fiberIn order deformation the raw ze to close, the configuration which is configurated. Advantages With the simple optical fiber containment structure of configuration varyingIt is possible to detect rank securely.
