Description

Technical Field

[0002] Geotechnical engineering exploration refers to the activities of identifying, analyzing, evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and compiling exploration documents according to the requirements of the construction project. If the exploration work is not in place, adverse engineering geological problems will be exposed. Even if the design and construction of the upper structure have reached high quality, it will inevitably be damaged. Most of the equipment used in the exploration process requires the use of support frames for auxiliary support.

[0003] In the prior art, the Chinese utility model patent with authorization announcement number CN 212105768 U discloses an exploration support frame structure for geotechnical exploration, including a support and multiple arms, the multiple arms are distributed around the support, and the top of the arm is hinged to the support, a positioning assembly for controlling the opening angle of the multiple arms is arranged below the support, and a guide cylinder is arranged vertically at the center of the bottom of the support, and a drilling assembly is arranged on the top of the support. The beneficial effect is that the utility model arranges a detachable folding support frame on the outside of the drilling equipment, folds up three groups of arms and separates the drilling assembly from the support, so as to reduce the equipment structure for easy carrying and transportation, and at the same time, the opening angle of the arm can be adjusted according to the ground conditions of the exploration area, so that the support is more stable and practical.

[0004] Compared with the prior art, the above solution has poor grip during use. When using a drill rod for drilling, the drill rod will shake and there will be a reaction force, which may cause the device to separate from the ground, resulting in poor accuracy of geotechnical exploration.
