GROUND LAYER SINKING VOLUME MEASUREMENT SYSTEM USING

摘要

PURPOSE: A measuring system for a differential settlement is provided to easily repair and replace a sensor when the sensor is out of order by locating the sensor on the ground. CONSTITUTION: A measuring system for a differential settlement comprises multiple rods(110), a sensor(120), and a casing(140). The rods are inserted into an excavated hole(10). The sensor is installed on the top of an opening of the excavated hole to measure a relative displacement of the rods and a ground surface. The casing is movably installed on the top end of the excavated hole. The sensor is moved with the casing.
