Description

technical field [0001] The invention relates to the technical field of ground fissure engineering measuring devices, in particular to a ground fissure geological disaster measuring device. Background technique [0002] Ground fissures are mainly fissures or faults that occur in the soil layer. Ground fissures are often combined in multi-level echelon on the surface, and some can be connected into huge cracks. With a large number of engineering construction activities (such as underground ore body excavation, slope excavation, foundation pit excavation, groundwater exploitation, etc.), ground fissures are more and more common. Undoubtedly, the construction of these projects will inevitably lead to a certain scale of cracking on the surface around the excavation, and even cause geological disasters such as surface subsidence and landslides, which will bring serious damage to project construction activities and the safety of people's lives and properties. threatened to cause h...

Problems solved by technology

[0003] However, due to the complex environment in the ground fissures, obstacles such as fillers or steel bars are often blocked in the ground fissures, causing the existing monitoring probe components to be disturbed. When detecting the depth, the existing monitoring probe components often detect obstacles. The depth of the current ground fissure will be judged and obtained at the time, and the error caused will have a serious impact on the subsequent engineering construction. Not only that, because the ground fissure is affected by the environment, its width dimension also has a deformation amount, and the measurement of ground fissures in general The width is all done manually, resulting in inaccurate measured values ​​when there is deformation in the ground fissures. Based on this, the existing ground fissure measurement technology is still not perfect, and there is a lot of room for improvement. Therefore, a new type of ground fissure is urgently needed.
