Description

Technical Field

[0001] The utility model relates to the technical field of geological monitoring, in particular to a device for measuring geological fractures in hydrogeology, engineering geology and environmental geology. Background Technique

[0002] Hydrogeology, engineering geology and environmental geology mainly conduct investigation and survey on groundwater resources, engineering construction and geological conditions of the natural environment. Geological survey work is an important means of collecting all geological data in the working area and dynamic supervision and management of reserves, and can systematically study geological characteristics such as strata, structures, rocks, and minerals. Due to crustal movement, cracks often appear on the ground. For further research, it is often necessary to measure the length of the cracks.

[0003] In human activities such as water conservancy project construction, excavation, blasting, and mining, it often causes the damage and instability of rock and soil masses, resulting in the occurrence of surface cracks. The occurrence sites of the cracks are exactly the areas where the stress of the rock and soil masses is concentrated or the strength is relatively low. This may also be a precursor to geological disasters such as ground subsidence and collapse. Its development and change will naturally affect the safety of normal engineering construction, production, transportation roads, and surface buildings. Therefore, it is necessary to measure geological fractures.

[0004] When the existing device for measuring geological fractures in hydrogeology, engineering geology and environmental geology is used to survey areas with different geological conditions, due to the variable differences in the on-site terrain, when the ground is uneven, it is easy to cause the entire geological fracture measuring device to be difficult to ensure a horizontal state, and it is easy to cause measurement errors during measurement, thus affecting the accuracy of measurement data. In addition, the device is not easy to measure the depth of the crack, and its use has great limitations. Therefore, a device for measuring geological fractures in hydrogeology, engineering geology and environmental geology is proposed. By rotating the handle to adjust the upper and lower positions of the support plate, the depth of the crack can be measured, and by adjusting the angle of the support plate through the handle, the measurement of the support plate can be kept horizontal.
