Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and in particular to a rock and soil depth measuring device used in geological exploration. Background Art

[0002] Geological surveys are focused investigations and studies of a specific area's geological conditions, including rocks, stratigraphic structures, minerals, groundwater, and landforms. During geological surveys, it's often necessary to measure the depth and geological conditions of rock and soil, providing the engineering details and geotechnical data needed for foundation design and construction, as well as foundation reinforcement when necessary.

[0003] When conducting geological surveys, it is necessary to drill holes and then use corresponding measuring devices to detect the depth of rock and soil. When using measuring cables for measurement, it is easy for the measuring cables to adhere to impurities on the inner wall of the exploration hole, which in turn causes a lot of impurities to accumulate on the surface of the measuring cables. In the geological exploration process, it is usually necessary to perform depth detection work on multiple boreholes, and it is necessary to move, unfold, and store them at multiple boreholes. In the outdoor geological exploration process, it is necessary to ensure that the work is fast, stable, and efficient. For this reason, a rock and soil depth measuring device for geological exploration is proposed. The device is easy to move at each borehole and can quickly locate and perform depth measurement when it moves to the borehole position. After the rock and soil depth measurement, the measuring cable can be cleaned during the rope collection process, thereby preventing the measuring cable from being attached to silt and affecting subsequent geological exploration work, so that after one rock and soil depth measurement, it can be quickly used for rock and soil depth measurement work at the next location, which is more suitable for outdoor geological exploration work.
