Static and dynamic fluid resistivity testing device and method

Abstract

The invention discloses a static and dynamic fluid resistivity testing device, which comprises drainage end parts, a resistivity system and a negative pressure device, and is characterized in that the drainage end parts are arranged at the two ends of the resistivity system, and the negative pressure device is arranged on the resistivity system; the resistivity system comprises a fluid channel, an insulating layer, a metal reinforcing layer and a shell are sequentially wrapped outside the fluid channel, a metal heat conduction layer is arranged on the side edge of the fluid channel, the fluid channel is connected with a temperature compensation piece through the metal heat conduction layer, and an electrode set is arranged on the fluid channel. The hollow pipe body is used for measuring the resistance of the conductive fluid, various influences on the shape of a conductive circuit in the wire laying process are reduced, the conductive fluid measured in the mode is easy to recycle, material loss in the research process is reduced, and the device is simple in structure, easy and convenient to operate and easy to carry.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a static and dynamic fluid resistivity testing device and method. Background technique [0002] With the vigorous development of industry, the number of factories has gradually increased. The production of the factory will inevitably produce a large amount of sewage, and the sewage contains many harmful components. Once these components are discharged into the water body or soil, it will not only destroy the ecological environment, but also endanger the health of organisms and human beings. Therefore, strengthen the treatment of factory sewage. Handling work is an important matter related to the harmonious development of society. In recent years, the state has increased investment in sewage treatment, and sewage treatment has achieved initial results. However, after the sewage from many factories is treated, it still contains a relatively high amount of total ni...
