Technical field

The utility model relates to the technical field of geotechnical engineering survey, and is specifically a measuring device.

Background technique

Geotechnical engineering survey refers to the activity of identifying, analyzing, and evaluating the geological, environmental characteristics and geotechnical engineering conditions of the construction site and preparing survey documents based on the requirements of the construction project. If the survey work is not in place, poor engineering texture problems will be exposed. Even if the design and construction of the superstructure reach high quality, it will inevitably be damaged. Different types and different scales of engineering activities will have different impacts on the geological environment, and vice versa. Different geological conditions will bring different effects to project construction.

After searching, for example, Chinese patent documents disclose a measuring device for geotechnical engineering survey [Application No.: CN202020873649.5; Publication No.: CN212206672U]. This measuring device for geotechnical engineering survey includes a base. A through hole is provided in the middle of the base. Support columns are fixedly connected to the upper end of the base and located outside the through hole at the four corners. The upper ends of the four groups of support columns are fixedly connected to each other. Top plate, the upper left and right sides of the top plate are fixedly connected with hydraulic cylinders.

The device disclosed in this patent can directly sample the core through the core drill bit, making it more convenient during the sampling process. However, during use, the core drill bit cannot be blocked, resulting in the core being located above when taking the core. It will first enter the inside of the core drill bit, and when sampling cores at other depths, the core cannot enter the inside of the core drill bit again. As a result, the core inside the core drill bit is not the core at the required sampling depth, resulting in insufficient core sampling. Accurate, affecting the sampling effect of the core, and the core cannot be fixed during the removal process, causing the core to easily fall when the staff takes it out. At the same time, the drill pipe and core drill bit of the device are inconvenient to disassemble, resulting in The staff need to squat down when taking out the core, which makes it inconvenient for the staff to take out the core. Not only is the removal more cumbersome, but it also increases the difficulty for the staff to take out the core, thus reducing the efficiency of geotechnical survey.
