Abstract

The present invention provides a soil accelerated corrosion test device and test method, the test device comprises a gas supply system, an test system and a spray liquid replenishment system, the test system comprises a test box, a ventilation device and a sealing cover plate, the ventilation device consists of a plurality of The hollow partitions with through holes on the side walls are connected. The adjacent hollow partitions are used to store experimental soil and test pieces. The bottom of the ventilation device is provided with an air inlet. The gas supply system includes oxygen cylinders, nitrogen cylinders and Gas flow control device, the gas flow control device is used to control the ratio of oxygen delivered by the oxygen cylinder and nitrogen delivered by the nitrogen cylinder to adjust the concentration of oxygen. The oxygen after the concentration adjustment enters the experimental box through the air inlet, and the spray replenishment system It is used to replenish the experimental soil to adjust the moisture content of the experimental soil. The invention can solve the problems that the soil corrosion research in the prior art is limited, and the corrosion products of different samples will cause soil pollution and affect the experimental environment.

Description

technical field

[0001] The invention relates to the technical field of soil corrosion testing, in particular to a soil accelerated corrosion test device and test method. Background technique

[0002] The corrosion of metals in soil is one of the serious corrosion problems of metals. Various metal components buried underground, such as underground communication equipment, substation grounding grid equipment, various underground water pipes, gas pipes, oil and gas pipelines, etc. are constantly suffering from soil corrosion, causing oil, gas, and water to leak out. , and even cause floods, environmental pollution and other problems, bringing huge economic losses to the society. Therefore, it is of great practical significance to study the soil corrosion process of materials and its control.

[0003] At present, the conventional soil corrosion methods mainly include the outdoor field embedded slice test method and the laboratory simulation accelerated method. For conventiona...
