Real-time monitoring device and method for groundwater level and soil moisture in gully head landfill area

Abstract

The invention discloses a real-time monitoring device and a real-time monitoring method for groundwater level and soil moisture in a gully head landfill area. The monitoring device comprises a groundwater observation well arranged in a region to be monitored, wherein a throw-in type liquid level transmitter is placed in the groundwater observation well, and the throw-in type liquid level transmitter senses water level variation of groundwater and transmits data to an environment monitoring cloud platform by means of a data acquisition module; a plurality of soil moisture transmitters are arranged on the well wall of the groundwater observation well layer by layer, each soil moisture transmitter transmits acquired signals to a signal bus, the signal bus is connected to an environment monitoring host, the environment monitoring host is in wireless connection with the environment monitoring cloud platform, and a user can view real-time data through logging in the environment monitoring cloud platform and the environment monitoring cloud platform remotely; and the data acquisition module and the environment monitoring host are connected with a power supply module, and the power supplymodule comprises a storage battery and two power supply branch circuits. The monitoring method of the invention can be used for simultaneously monitoring real-time data of the groundwater level and soil moisture, reduces the workload and improves the data precision.

Description

technical field [0001] The invention belongs to the field of environmental monitoring and protection, and specifically relates to a device and method for real-time monitoring of groundwater level and soil moisture in a ditch head landfill area, which provides a data basis for exploring the damage causes of engineering measures in the ditch head landfill area on the Loess Plateau. Background technique [0002] The Loess Plateau is one of the birthplaces of ancient civilizations of the Chinese nation. The loess is fine-grained, soft and rich in mineral nutrients. Its favorable cultivation has bred generations of residents in the Loess Land. However, due to the special landform features, climate types and soil characteristics , it has also become one of the areas with the most serious soil erosion and the most fragile ecological environment in the world. In recent years, many ground subsidence and ground fissures have occurred during the construction of the gully protection pro...

AI Technical Summary

Problems solved by technology

Due to the special soil properties of the geological structure of the Loess Plateau, many engineering measures for gully protection are affected by the rise and fall of the groundwater level and the change of soil water content, which may easily lead to a large number of geological disasters. Due to the uneven settlement of the foundation, the concrete breaks and cracks occur
