[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing, and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and compiling investigation documents according to the requirements of the construction project. Its purpose is to use testing means and methods to investigate, study, analyze and judge the construction site, ensure the strength and stability of the foundation and take measures to prevent it from unacceptable deformation; propose the bearing capacity of the foundation, provide the project address and geotechnical engineering data required for basic design and construction, and strengthen the foundation when necessary. During the geotechnical engineering investigation process, it is usually necessary to use drilling equipment to drill holes in the ground, and then carry out subsequent work after drilling.

[0003] However, since the area that needs to be drilled during the geotechnical engineering investigation is not always suitable for longitudinal vertical drilling operations, the angle of the existing drilling device cannot be adjusted, and thus it cannot be used to drill rocks at different angles, which reduces the scope of use of the device. Therefore, we propose a drilling device for geotechnical engineering investigation to solve the above-mentioned problems. Utility Model Content
