Description

technical field [0001] The invention relates to the technical field of rock and soil monitoring instruments, in particular to a cable depth suspension device and system for a sliding inclinometer. Background technique [0002] The sliding inclinometer is an instrument specially used for monitoring the deep displacement and deformation of rock and soil foundations. Measurement of deep displacement of pit excavation, railway, road traffic slope or horizontal settlement of road surface. The inclinometer is generally composed of a measuring head, a calibration cable, a reading instrument, accessories, etc. One end of the calibration cable is connected to the measuring head, and the other end is connected to the reading instrument. [0003] At present, the inclinometer adopts the traditional forward and reverse measurement method: the inclinometer tube is embedded in advance. When measuring, first lower the measuring head from the upper end of the inclinometer tube, and then li...
