Description

technical field [0001] The invention relates to a self-propelled linear path rock and soil deformation monitoring device, which belongs to the fields of geotechnical engineering, geological engineering, and disaster prevention and reduction. Background technique [0002] The deformation monitoring of rock and soil mass is the main work content in the fields of geotechnical engineering, geological engineering and disaster prevention and mitigation. The rock and soil in nature may be deformed to varying degrees after artificial transformation or affected by natural factors such as rainfall, earthquakes, and water level changes, such as slopes, foundation pits, roadways, and foundations, or collapses, landslides, debris flows, etc. Ground subsidence, ground fissures and other geological disasters. The deformation of these rock-soil bodies will threaten the safety of human life and property to a certain extent. Therefore, it is necessary to carry out deformation monitoring of r...

Problems solved by technology

[0003] The disadvantage of point monitoring is that it can only monitor a limited number of points at the same time, and the obtained monitoring data can only represent the local deformation of the measuring point

If it is necessary to monitor the deformation of rock and soil in a large range, it is necessary to install a large number of sensors and supporting power supply, data acquisition, storage and transmission equipment, which is expensive

Disadvantages of linear monitoring technologies such as distributed optical fiber technology and cable time-domain reflection are that only deformation data on the monitoring path can be obtained, but deformation direction data cannot be obtained, and the deformation allowed by optical fiber is small. A large amount of deformation will break the optical fiber and cause the monitoring system to fail

The disadvantage of planar monitoring is that it requires a certain operating space. Equipment such as total stations, 3D laser scanners or radars need to be at a certain distance from the surface of the rock and soil to be monitored before they can work, and cannot be used in a narrow space.

In addition, monitoring equipment such as high-precision distributed optical fiber, time-domain reflection, 3D laser scanning, and radar mainly rely on imports from developed countries, which are expensive. scope of use
