Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, in particular to a geotechnical engineering drilling tool with an auxiliary positioning mechanism. Background Art

[0002] Geotechnical engineering treatment mainly controls the strength, settlement and deformation of rock and soil to ensure stability, mainly including slope stability, foundation treatment and other aspects related to rock and soil stability. Drilling tools are required during geotechnical engineering construction. The main function of drilling tools is to obtain physical and chemical properties data of underground rock and soil for geological survey.

[0003] However, when drilling in rock and soil, traditional geotechnical engineering drill tools generally first designate a place and then directly drill it with the drill tool. However, during the drilling process, due to some factors such as some stratum unevenness in the rock and soil, this direct drilling operation cannot ensure that the drill tool always moves in a straight line, which will cause deviations in the results of geological surveys and affect the efficiency of the survey. Therefore, there is an urgent need for a geotechnical engineering drill tool with an auxiliary positioning mechanism to solve this type of problem. Utility Model Content
