Description

Technical Field

[0001] The invention belongs to the technical field of exploration equipment, and in particular relates to a soil sample storage device used for geotechnical engineering survey. Background Art

[0002] Geotechnical engineering is a new technical framework established in the 1960s within civil engineering practice in Europe and the United States. Geotechnical engineering focuses on solving rock and soil engineering problems, including foundations, slopes, and underground engineering.

[0003] Geotechnical engineering studies rock and soil. Throughout their geological history, rock has undergone a variety of complex geological processes, resulting in a complex structure and geostress environment. Different types of rock in different regions often have significantly different engineering properties due to the different geological processes they have experienced. After emerging from the surface, rocks weather and form soils. These rocks may remain in place or be eroded and transported by wind, water, and glaciers and deposited elsewhere to form soil layers. The weathering environment, transportation, and deposition dynamics vary across different geological periods and regions. Consequently, soils not only have complex engineering properties but also exhibit strong regional and individual characteristics.

[0004] Before exploration or engineering construction, rock and soil need to be sampled and tested. There should be enough sampling points to facilitate the testing of various indicators and performance of rock and soil. The sampled rock and soil are placed in corresponding containers for easy carrying and testing. However, the current rock and soil storage tubes need to be taken out one by one when in use and the corresponding rock and soil samples are poured in, which has low work efficiency. The small opening of the rock and soil storage tube is not conducive to the pouring of rock and soil, and has poor practicality. Summary of the Invention
