Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering investigation, in particular to a portable investigation device which is easy to adjust. Background Art

[0002] Geotechnical engineering investigation is an activity to identify, analyze and evaluate the geological, environmental characteristics and geotechnical conditions of the construction site according to the requirements of the construction project; its main purpose is to study the geological conditions for the construction of various engineering buildings and the impact of construction on the natural geological environment, propose the bearing capacity of the foundation, provide a basis for design and construction, and serve the entire process of engineering construction; when conducting geotechnical engineering investigation, it is necessary to use investigation equipment. When the existing equipment is in use, it needs to be placed on the ground to investigate and detect the investigation direction. In actual use, when the portable investigation equipment is used, due to the different investigation terrains, the height of the investigation equipment will be adjusted to adapt to the investigation terrain. Most investigation equipment requires their own stability, so the bottom bracket of the investigation equipment needs to be adjusted one by one, which makes the subsequent height adjustment of the investigation equipment too troublesome.

[0003] A Chinese patent discloses an easily adjustable portable survey device (authorization announcement number CN218626162U). The patented technology can facilitate the height adjustment of the device by arranging a first groove inside a fixed plate, arranging a disc on the outer wall of a rotating rod, arranging a second groove inside the disc, arranging a baffle inside the second groove, arranging a spring and a clamping rod on the outer wall of the baffle, arranging a first extrusion plate on the outer wall of the disc, arranging a second extrusion plate at one end of the first extrusion plate, and arranging a third extrusion plate on the outer wall of the second extrusion plate, so that the third extrusion plate can squeeze the bracket. In the utility model, when the portable survey device is used, the height of the survey device can be adjusted to the survey terrain due to different survey terrains. The device does not need to adjust the bottom brackets of the survey device one by one, so that the subsequent height adjustment of the survey device is simple and convenient.

[0004] However, it has certain disadvantages: when the ground on which the survey device is placed is uneven, the equipment cannot remain level or stable, which can cause the equipment to shake or tip over during operation, thereby increasing the risk of equipment damage. In addition, the uneven ground prevents the survey device from being at the angle required for the survey, which has a certain impact on the survey results. Utility Model Content
