Description

A groundwater level monitoring device and a groundwater level monitoring method

Technical Field

The invention relates to the technical field of geological exploration, and specifically discloses a groundwater level monitoring device and a monitoring method.

Background technique

Hydrogeological exploration aims to understand the causes, distribution and movement of groundwater and surface water, including underground and surface hydrological surveys. Groundwater level monitoring is an important part of hydrogeological exploration. Groundwater level monitoring mainly investigates and studies the changes in water levels of upper underground stagnant water, phreatic water layers and confined water layers at different times of the year, and can provide factual basis for groundwater resource management, thereby facilitating the management of groundwater resources.

When monitoring the groundwater level, the user usually releases the water level gauge downward along the edge of the observation well. When the water level gauge contacts the groundwater, the device issues an alarm, and the user determines the distance between the groundwater level and the ground by observing the length of the scale used to release the water level gauge. If there is an obstacle on the well wall, the water level gauge may contact the obstacle, causing the measurement result of this measurement method to deviate, and the manual operation error is large. In addition, it only measures the distance from the ground to the water surface, without measuring the well depth and the actual water depth. The measurement effect is relatively simple and the measurement efficiency is low.
