A ground subsidence monitor

Abstract

The utility model belongs to the field of settlement monitoring technology, specifically a ground settlement monitor, including a horizontal plate, the inner wall of which is provided with a monitoring hole. The height of the adjustment plate is adjusted by turning the adjustment bolt, so that the adjustment plate and the initial position of the first scale line are kept at the same horizontal line, and the support rod is inserted into the fixed plate. At this time, the bottom surface of the elastic sleeve and the initial position of the second scale line are at the same horizontal line. When the ground settles, the horizontal plate will follow the ground settlement, and the degree of ground settlement can be observed by the distance between the settlement ring and the first scale line. At the same time, the horizontal plate descends to drive the adjustment plate, and the support rod is lowered by gravity, and the tension bolt is screwed into the tension sleeve so that the tension bolt is against the surface of the insertion rod, and the insertion rod is pulled out of the fixed plate by holding the tension sleeve. The degree of ground settlement can be understood by observing the distance between the bottom surface of the elastic sleeve and the second scale line, without lowering the head or squinting, which is convenient for observation and not easy to cause reading errors.
