Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for geotechnical engineering investigation. Background Art

[0002] Geotechnical engineering investigation is the use of testing means and methods to investigate, study, analyze and judge the construction site, study the geological conditions for the construction of various engineering buildings and the impact of construction on the natural geological environment; study the measures to ensure the strength and stability of the foundation and prevent it from unacceptable deformation when the foundation, base and superstructure work together; propose the bearing capacity of the base, provide the project address and geotechnical engineering data required for foundation design and construction, and carry out foundation reinforcement when necessary.

[0003] The China Patent Network discloses a drilling device for geotechnical engineering survey, with the publication number CN221032406U. The adjustment handle is rotated to drive the sleeve to rotate, and the distance between the second screw and the first screw can be adjusted, thereby adjusting the angle of the support column. The lifting motor is started to drive the threaded rod to rotate, thereby driving the lifting plate on the slider to move up and down. The drilling motor is started to drive the drill bit to rotate and drill the ground. The vibration generated during drilling will cause the fixed box to vibrate. The baffle on the shock-absorbing rod compresses the buffer spring, and the pressure generated by the buffer spring and the vibration offset each other to achieve shock absorption. Since the drill bit is prone to wear during long-term use, it needs to be replaced and maintained regularly. However, the drill bit in this patent is not easy to disassemble, and thus it is not easy to replace and maintain the drill bit, and its practicality is not high.

[0004] Therefore, a drilling device for geotechnical engineering investigation is proposed. Utility Model Content
