[0002] Engineering survey refers to the activities of mapping, exploring and testing the terrain, geology, hydrology and other conditions, and providing corresponding results and data to meet the needs of planning, design, construction, operation and comprehensive management of engineering construction. The survey, design, processing and monitoring activities in geotechnical engineering also fall within the scope of engineering survey.

[0003] In the process of conducting electromagnetic and direct current geophysical exploration, it is necessary to excavate the surface to dig up the dry surface soil layer to expose the clay layer below, and then insert a conductive copper rod or iron rod into the ground to input current into the ground. Usually, the excavation depth does not exceed 1m, and the soil layer at this depth is still relatively dry. At this time, it is necessary to add a conductive medium (such as salt water) to enhance the coupling strength between the conductive copper rod and the soil layer and increase conductivity.

[0004] The existing technology for this work usually adopts manual excavation and exploration, and the brine is transported to the excavation location and poured into the excavated pit by manpower, which will lead to high labor intensity of workers and increase investment costs.
