Groundwater-based depth measurement method

Abstract

The invention discloses a groundwater-based depth measurement method, and belongs to the field of groundwater measurement. The groundwater-based depth measurement method uses a water level measuring device and cooperates with steps of the groundwater depth measurement method for operation. When the water level on the ground is between two safety lines, the water level measuring device can measureand record the distance between the ground surface and the ground. When the water level on the ground is at the lower end of the first safety line, the actual depth of the ground and the depth from the diving layer can be obtained in real time under the cooperation of the water level measuring device and an unmanned submersible, so that the depth data of the ground can be measured and recorded. Atthe same time, the abnormal water level detected can be subjected to real-time data feedback and corresponding emergency measures can be taken by the connection between related system to reduce the impact on the society and economy caused by abnormal changes in water levels on the ground and inaccurate measurement of water levels.

Description

technical field [0001] The invention relates to the field of groundwater measurement, in particular to a groundwater-based depth measurement method. Background technique [0002] The relationship between groundwater and human beings is very close. Well water and spring water are the most groundwater used by human beings every day, occupying an irreplaceable position. However, groundwater can also cause some hazards, such as too much groundwater, which can cause railways and roads to collapse, submerge mining roadways, and form swamps. With the gradual expansion and deepening of the breadth and depth of human activities on the earth, both shallow and deep groundwater resources are affected to varying degrees. The results of the large-scale land and resources survey project "Investigation and Evaluation of Groundwater Pollution in the North China Plain" carried out by the Institute of Hydrology and Environmental Geology of the Chinese Academy of Geological Sciences show that ...

Problems solved by technology

[0006] The above-mentioned invention needs to lower the wires during the measurement process. This process is manually operated accurately, so that the measurement of the water level is not time-sensitive, and the groundwater is running water with fluidity. The measurement device is lowered through the wires. In the water, it will flow with the water. At this time, if the length of the discharge line is used as the depth of the water level change, the measurement result will be inaccurate.
