Title:
APPARATUS AND METHOD FOR MEASURING SUBSIDENCE USING PRESSURE GAUGES
Document Type and Number:
WIPO Patent Application WO/2022/220341
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and method for measuring subsidence using pressure gauges, the apparatus comprising: a plurality of pressure gauges which are installed along the ground surface at a subsidence reference point and a plurality of measurement points to be measured and measure the pressure displacement at each of the measurement points; a pressure delivery pipe which is filled on the inside with a liquid supplied from a tank installed at the subsidence reference point and delivers pressure to each of the pressure gauges; and a measurement terminal which is connected to each of the pressure gauges via an optical cable and measures the subsidence of the ground by converting the pressure displacement measured at each of the pressure gauges into a height displacement. The plurality of pressure gauges and the pressure delivery pipe are installed in the ground that is to be measured, and the subsidence of the ground can be measured by measuring the displacement of the pressure delivered to each of the pressure gauges from the liquid filling the pressure delivery pipe.
