Description

Technical Field

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

[0002] Geotechnical engineering investigation is a very important link in engineering construction. The main purpose is to understand the geological conditions of the construction site and provide a scientific basis for engineering design and construction. This process includes the investigation and research on the physical and mechanical properties of surface and underground rock and soil masses, groundwater conditions, crustal stability, etc. When investigating rock and soil, a soil sampler is needed to take samples. The soil sampler is used to extract undisturbed soil from the lower layer of test soil as a specimen to understand its properties. To better understand the properties of the base layer, sometimes undisturbed soil needs to be taken from a deeper depth. For this reason, a connecting rod is added in the middle of the soil sampler, which is called the soil sampler. When the existing sampler takes samples, the handle and the sampling rod are generally fixedly connected. And in order to make the force more uniform, the handle and the sampling rod are in a vertical structure. In this way, during the process of moving and transporting, the vertical handle and sampling rod will occupy a large space, which is not convenient for moving and transporting. Moreover, due to different geotechnical sampling environments, the required lengths of the sampling rods are also different. It is rather troublesome to carry multiple sampling rods of different lengths at the same time. If a longer sampling rod is directly used, it is also inconvenient to carry.
