Description

Technical Field

[0001] The utility model belongs to the technical field of hydrological dynamic monitoring and relates to a borehole water level and water temperature monitoring circuit. Background Art

[0002] The observation of water level in the borehole requires that the borehole water level be observed once after the drill is lifted and before the drill is lowered, in order to ensure accurate recording of the changes in water level inside the borehole. The observation of water temperature requires that the water temperature be measured at least once for each exposed layer, because the change in water temperature can reflect the temperature conditions underground, which is of great significance for the study of geothermal resources and groundwater flow paths. Through regular water temperature observation, the changing trend of underground temperature can be recorded, providing an important reference for geological exploration and groundwater management. At present, the method for measuring water level and water temperature in the borehole during field drilling construction in China mainly adopts the traditional rope measurement (electric depth sounding) method, which involves manual laying out of lines and reading measurements.
