Description

Technical Field

[0001] The utility model relates to the technical field of groundwater level monitoring, in particular to a groundwater level monitoring device for geological survey. Background Art

[0002] The groundwater level refers to the elevation of the water surface in an underground aquifer. Based on the time of drilling observation, it can be categorized as initial water level, stable water level, high-water level, low-water level, and pre-freeze level. During engineering geological surveys, monitoring of the groundwater level in nearby areas is often necessary to ensure smooth project progress.

[0003] At present, when monitoring groundwater levels during geological surveys, the conventional practice is to drill a hole in the area to the groundwater layer. The surveyor holds a connecting wire in his hand and continuously lowers a probe from the hole. When the probe touches the water, an audible alarm sounds. The surveyor then observes the scale of the connecting wire in his hand and records the depth of the groundwater level. In this measurement method, the probe may collide with the inner wall of the hole, which may easily damage the probe, and there is no guarantee that the probe will move vertically downward, which in turn affects the accuracy of the water level measurement.
