DEVICE AND A METHOD FOR MEASURING THE UNDERGROUND SUBSIDENCE OF EACH LAYER, CAPABLE OF RE-USING LOAD CELLS BY DISASSEMBLING WHEN A SUBSIDENCE MEASUREMENT IS NOT NECESSARY
PURPOSE: A device and a method for measuring the underground subsidence of each layer are provided to minimize artificial errors and measurement errors by automatically measuring or monitoring and to measure an occurrence pattern and the accumulation of the subsidence by continuously monitoring.;CONSTITUTION: A device for measuring the underground subsidence of each layer comprises anchors(10-1,10-2,10-3), a non-flexible connection materials, behavior guide pipes(12-1,12-2,12-3), load cells(20-1,20-2,20-3), and a data logger(30). The anchors are inserted into a subsidence measuring hole(1) at different depths based on a ground surface and fixed on the ambient ground of the subsidence measuring hole with a fixing member at different heights. The non-flexible connection material is connected to the each anchor. The behavior guide pipes protect the non-flexible connection material so that the non-flexible connection material is moved by the anchor. The load cell is installed on the ground and connected to the non-flexible connection material, thereby detecting tensile force respectively applied to the non-flexible connection material from the anchors. The data logger converts data measured by the load cells into display displacement or subsidence displacement. The subsidence of each layer is measured base on the tensile force applied to the load cell through the non-flexible connection material in the subsidence of the anchors.;COPYRIGHT KIPO 2013
