Embodiment Construction
[0026] When designing the layout scheme of the fixed borehole inclinometer, due to the limitation of the bearing structure of the traditionally designed fixed borehole inclinometer, its maximum inclinometer dimension is 2, which can only measure the deep displacement and deformation in the horizontal direction, which is difficult Obtain displacement data in the vertical direction. In addition, because the traditional two-dimensional fixed borehole inclinometer needs to be used with pre-buried inclinometer pipes, it is very inconvenient during construction and installation; affect the measurement accuracy of the inclinometer.
[0027] In view of this, the designer of the present invention has designed a three-dimensional deformation measurement device and system through long-term exploration and trial, as well as multiple experiments and efforts, and continuous reform and innovation, which can better improve the above problems.
[0028] In order to make the purpose, technical ...

The embodiment of the invention provides a three-dimensional deformation measurement device and system, and belongs to the technical field of monitoring equipment. The three-dimensional deformation measurement device comprises at least two cylinder units and a hydraulic device, wherein the at least two cylinder units are arranged below the ground surface and used for measuring horizontal displacement data, and the hydraulic device is connected with a free end, which is away from the ground surface, of each cylinder unit and used for measuring vertical displacement data. Two adjacent cylinder units are provided with a two-dimensional flexible joint therebetween used for hinging the cylinder units. The outer wall of each cylinder unit is provided with a rubber inflatable sleeve in a sleeved manner. Each cylinder unit comprises a cross-shaped bearing and two fixed cylinder connecting pieces connected through the cross-shaped bearing. Each two-dimensional flexible joint has two degrees of freedom in the horizontal direction. The three-dimensional deformation measurement device can effectively improve the dimension and accuracy of measurement for deformation data.
Description
technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to a three-dimensional deformation measuring device and system. Background technique [0002] In the process of monitoring the deep horizontal displacement of rock and soil layers, borehole inclinometers are usually used. When building a real-time monitoring system, a fixed inclinometer can be selected for long-term monitoring. Before the installation of the monitoring system, it is necessary to drill a certain depth of the inclinometer hole at the monitoring position and install the inclinometer tube. There are two sets of guide grooves along the sliding direction of the slope body and vertical to the slope body sliding direction in the inclinometer tube. It moves to the monitoring position under the guidance of its guide wheel and the guide groove of the inclinometer tube. Each fixed inclinometer measures the inclination angle change at the installation position of ...
