Description

Technical Field

[0001] The invention relates to a drilling sampling device, in particular to a hydraulic and environmental geological drilling sampling device. Background Art

[0002] Water conservancy and environment refers to hydrogeology, engineering geology and environmental geology. Hydrogeology mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational use, the adverse effects of groundwater on engineering construction and mining and their prevention and control, etc. The main research contents of engineering geology involve geological disasters, rocks and Quaternary sediments, rock mass stability, earthquakes, etc. In order to find out the geological conditions of various engineering sites, a comprehensive evaluation of the sites and various geological problems related to them is carried out, and the possible changes and effects of geological conditions under the action of engineering construction are analyzed and predicted. The optimal site is selected, and engineering measures to solve adverse geological problems are proposed to provide a reliable scientific basis for ensuring the reasonable design, smooth construction and normal use of the project. Environmental geology mainly studies the interaction and influence between human activities and geological environment. Especially since the 1950s, global environmental geological problems have become increasingly acute, including water shortage, water quality deterioration, ground subsidence, karst collapse, seawater infiltration, landslides, desertification and multiple endemic diseases, which show the huge impact of geological environment on humans. Human understanding and research on geological environment has reached a new height.
