SUBSIDENCE MEASUREMENT SYSTEM USING ANCHOR AND SUBSIDENCE MEASUREMENT METHOD USING SAME

摘要

A subsidence measurement system using an anchor and a subsidence measurement method using same provided in the present invention include a steel rod that is disposed to be inserted into a subsidence measuring hole and extend to a fixed point; an elastic wing that is provided at a lower end of the steel rod, is formed of an elastic material, and fixes the lower end of the steel rod to the fixed point to be elastically supported; an anchor that is disposed to be capable of a vertical movement in the steel rod, and is inserted into and fixed to an inner wall of the subsidence measuring hole when put into operation; and a subsidence rod that is connected to the anchor to extend upward, and is disposed to be capable of a vertical movement with the anchor. Accordingly, in the present invention, the steel rod that is disposed in the subsidence measuring hole is fixed to be elastically supported at the fixed point by the wing having elasticity, and thus a buffering operation against an external force can be performed. Also, a movement of the fixed point is suppressed so that the accuracy of a subsidence displacement value is increased. In addition, the subsidence rod that is connected to the anchor is primarily protected by a protection pipe, and thus a horizontal displacement of the subsidence rod, which is attributable to the collapse of the inner wall of the subsidence measuring hole, can be prevented. Therefore, the error of the subsidence displacement value can be decreased by accurately reflecting the vertical movement of the subsidence rod, and the protection pipe is supported by an elastic member so that a relaxation area, in which the displacement secondarily generated in the subsidence rod can be converged, can be ensured and the reliability of the subsidence displacement value can be increased.;COPYRIGHT KIPO 2014
