Description

Technical Field

[0001] The utility model relates to the technical field of experimental devices, in particular to a novel soil corrosion experimental device. Background Art

[0002] Studies have found that most buried pipelines are in service in soil environments, and soil corrosion poses a severe challenge to the safe service of pipelines. In addition to a large number of corrosive ions and soil microorganisms in the soil, stray current in the soil is also one of the main reasons affecting the corrosion of buried pipelines. The traction current of the urban rail transit system escapes from the track and leaks into the earth and the surrounding environment, which is called stray current. After the stray current escapes into the soil, it will greatly accelerate the corrosion of buried metal equipment. Soil conditions such as soil moisture content, air permeability, temperature, pH value, dissolved ion types and concentrations, redox potential, resistivity, organic matter content, and microorganisms, as well as various complex external environments will affect the stray current on buried metal equipment, especially the corrosion of metal pipelines in the soil;

[0003] The experimental methods for the soil corrosion resistance of buried pipelines are mainly divided into outdoor field burial and indoor accelerated corrosion experiments. Outdoor field burial is to bury a large number of specimens in typical soil, and then dig them according to a certain burial cycle to measure the weight loss rate and corrosion rate of the specimens. This method is simple and easy to implement. The observed surface morphology of the specimens and the measured data can more intuitively and truly reflect the quality of the corrosion resistance of the material. Therefore, it has been widely used in the early research on soil corrosion at home and abroad. However, due to its long experimental cycle, it is impossible to accurately and timely obtain the corrosion details of the material in the soil and the information on the corrosion dynamics, so it cannot meet the needs of in-depth research on the soil corrosion of materials. Indoor accelerated corrosion experiment is an experimental method that artificially controls the experimental conditions by simulating accelerated corrosion, and strives to judge the tendency of the material to undergo a certain corrosion in various soils in a shorter time. However, for the special service environment of charged soil, the current experimental equipment cannot meet the research requirements. Utility Model Content
