Background Geotechnical engineering investigation refers to the steps of finding out, analyzing and evaluating the geology, environmental characteristics and geotechnical engineering conditions of a construction site according to the requirements of the construction engineering, compiling investigation files, researching, analyzing and judging the construction site by using test means and methods, researching and constructing the geology conditions of various engineering buildings and the influence of construction on natural geological environment, researching the foundation, the foundation and the upper structure to work together, ensuring the strength and the stability of the foundation and preventing the foundation from intolerable deformation, providing the bearing capacity of the foundation, providing engineering addresses and geotechnical engineering data required by foundation design and construction and foundation reinforcement when necessary, and drilling by using a drilling device when the geotechnical engineering is investigated. However, existing treatment devices suffer from the following disadvantages: When the drilling device is used in the existing equipment, such as CN218150730U, the drilling device relates to the technical field of geotechnical drilling, and discloses a drilling device for geotechnical engineering investigation, the drilling device comprises a fixing frame, a sliding groove is formed in the outer side of the fixing frame, a sliding seat is connected to the outer side of the sliding groove in a sliding mode, a driving motor is fixedly arranged on one side of the sliding seat, and a drilling rod and a drill bit are fixedly connected to an output shaft of the driving motor. The utility model realizes the movement of twice distance under the same length compared with the traditional hydraulic driving downward movement, the screw transmission downward movement and the cylinder driving downward phase movement, thereby amplifying the movement path of the driving motor of the drilling device by twice, solving the problems that the driving motor of the current drilling device is generally in the way of adopting hydraulic telescopic movement, screw transmission movement, cylinder telescopic movement and the like, the three driving modes can only ensure that the driving motor of the drilling device can move a certain position to be limited, such as hydraulic driving, cylinder driving and screw transmission are completely dependent on the length of the self, and the driving motor of the drilling device can not move downward to drill and take rock and soil when the length is limited, thereby reducing the sampling exploration efficiency.
