Apparatus and method for real-time monitoring of groundwater level and soil moisture of gully head landfill area

An apparatus for real-time monitoring of groundwater level and soil moisture of a gully head landfill area for Gully Consolidation and Highland Protection (GCHP), comprising:

• a groundwater observation well, set up in a monitoring area in a middle of the gully head landfill area for GCHP;
• a drop-in liquid level transmitter, placed in the groundwater observation well and configured to sense a water level change of groundwater;
• a plurality of soil moisture transmitters, arranged on a wall of the underground water observation well in layers and configured to sense soil moisture;
• a data collection module, configured to receive data from the drop-in liquid level transmitter and transmit the data to an environmental supervision cloud platform;
• and
• an environmental monitoring host, configured to receive data from the soil moisture transmitters and transmit the data to an environmental monitoring cloud platform;
• wherein
• a bottom of the groundwater observation well is sleeved with an outer tube, bottom end of the groundwater observation well is closed, a screw cover is provided in an upper part of the outer tube, a hole for inserting the groundwater observation well is reserved in a center of the cover, water inlet holes are evenly provided in entire wall of the outer tube, and outside the wall is provided with a fine sand layer, a medium sand layer, and a coarse sand layer from inside out;
• the groundwater observation well extends to the ground, water inlet holes are provided in a portion of the groundwater observation well wrapped by the outer tube, and the water inlet holes and a portion below the water inlet holes are wrapped with a layer of geotextile;
• wherein the soil moisture transmitter is fastened on the wall of the groundwater observation well through a buckle, the buckle comprises a first semicircular position fixing structure and a second semicircular position fixing structure, the first and second position fixing structures each are provided with a bolt hole on the top, and are fastened to the groundwater observation well by using a bolt, a cylindrical protrusion is provided in the middle of an outer side of the second semicircular position fixing structure, three strapping grooves are reserved on the cylindrical protrusion, a probe of the soil moisture transmitter is tied to the strapping groove, and a combing hole is provided next to the cylindrical protrusion and configured to fasten and comb wires of the soil moisture transmitter.
