Method for observing water level of multilayer underground water

Abstract

The invention discloses a method for observing the water level of multilayer underground water. The method comprises the following steps: S1, punching; S2, preparing a pipe; S3, observing a water level; S4, transmitting signals; S5, receiving the signals; S6, arranging data. A visual observation method is adopted, the water pump is used for pumping underground water at different heights for observation, and the height of the underground water level is visually observed. Equipment used in the method is ingenious, the equipment is not easy to damage, manufacturing cost is low, the underground water level observation device is durable in use, a large amount of equipment funds can be saved, popularization and installation of the water level observation device are facilitated, and scientific research funds are saved. The method can observe the underground water level in a circulating mode, cannot damage the underground water level, protects ecology, can observe the underground water level for a long time, collects data, and lays a data foundation for other hydrological scientific researches.

Description

technical field [0001] The invention relates to hydrogeological observation technology, in particular to a method for observing multi-layer groundwater levels. Background technique [0002] The groundwater level is the elevation of the groundwater surface relative to the datum. Usually calculated in absolute elevation. The elevation of the diving surface is called "diving level"; the elevation of the confined water surface is called "confined water level". According to the drilling observation time, it can be divided into initial water level, stable water level, water level in wet season, water level in dry season, and water level before freezing. [0003] The reasons for the decline of the groundwater level are mainly: 1. Human factors, such as overexploitation and utilization by humans. 2. Natural factors, such as the elevation of the terrain caused by earthquakes, the sinking of underground rivers, etc.; the diversion of rivers; changes in climate, etc. [0004] There...

AI Technical Summary

Problems solved by technology

What is unreasonable is agricultural flood irrigation, excessive irrigation water and untimely drainage, which will lead to the rise of groundwater level and even cause secondary salinization disasters

[0005] Based on the above reasons, the change of the groundwater level requires a scientific method for observing the groundwater level. The observation results of the existing technology are not intuitive when observing the groundwater level. A large number of sensing devices are used, which is not only inconvenient for observation, but also the observation result is not good Intuitive, especially for the observation of multi-layer groundwater level, therefore, a new method of observing multi-layer groundwater level is needed
