STRUCTURAL ELEMENT, PARTICULARLY TENSILE STRENGTH UNIT OF SOIL OR ROCK ANCHOR, PRESSUREPROOF UNIT OF PILE, PRESTRESSED CONCRETE STRUCTURE AND MONITOR FOR CLAMPING UNIT FOR DIAGONAL CABLE BRIDGE ROPE

摘要

PURPOSE: To make it possible to directly get to know about deterioration or damage of a tensile strength unit even when an important part of a structural member is incapable of being approached from the outside in a monitor device for a structural element, in particular for tensile strength unit of soil or rock anchor, bearing unit of pile, prestressed concrete structure and compression unit of a cable stayed bridge rope. CONSTITUTION: A sensor conduit 15 provided in the inside or the outside of at least a structural element 1 for receiving at least one sensor 16 is included, the sensor 16 is provided in the sensor conduit 15 in a movable and/or a detachable manner. An evaluation device 18 detects the presence of corrosion, cracks, overloads, overextensions and tension relaxation from at least one sensor signal.
