Problems solved by technology
[0003] Similar to the current geotechnical survey and drilling, there are still the following deficiencies: when drilling into the rock and soil, the equipment is prone to deviation due to the influence of environmental factors when drilling into the underground rock formation, which affects the normal survey and detection results. On the one hand, when the equipment is drilling downward, the equipment drilling structure and the equipment moving downward structure rotate at the same time, which requires too much energy medium to pull the equipment drilling structure and the equipment moving downward structure to rotate, which consumes more energy

The invention provides a geotechnical investigation drilling deviation prevention device, and relates to the technical field of geotechnical investigation equipment. A U-shaped supporting frame is fixedly connected to the upper portion of the front end of the supporting base, sliding grooves are formed in the left side and the right side of the interior of the supporting frame respectively, a telescopic piece is fixedly connected to the middle of the upper portion of the interior of the supporting frame, and a limiting frame is fixedly connected to the front end of the interior of the supporting base and located under the supporting frame. Two limiting plates are slidably connected to the middle position in the limiting frame. A driving motor at the front end of a connecting frame is started, a universal joint is driven to rotate when the driving motor rotates, a drill bit below the universal joint is driven to rotate through cooperation of the driving motor and the universal joint, and the drill bit is limited through two limiting plates in a limiting frame. The problems that when rock and soil are drilled, deviation is prone to occurring due to the influence of environmental factors when equipment drills into an underground rock stratum, and the normal exploration and detection effect is affected are solved.
Description
technical field [0001] The invention belongs to the technical field of geotechnical investigation equipment, and more particularly, particularly relates to a deviation prevention device for geotechnical investigation and drilling. Background technique [0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing and evaluating the geological, environmental characteristics and geotechnical engineering conditions of the construction site and compiling investigation documents according to the requirements of the construction project. The purpose of geotechnical engineering investigation is to use testing methods and methods Investigate, analyze and judge the construction site, study the geological conditions of construction of various engineering buildings and the impact of construction on the natural geological environment; when the foundation, foundation and superstructure work together, ensure the strength and stability of the foundation a...
