Multifunctional electroosmosis experimental instrument and using method thereof

Abstract

The invention discloses a multifunctional electroosmosis experimental instrument and a using method thereof. The instrument comprises a box body, an electronic scale and a hanging frame, the box bodyis arranged on the electronic scale, the hanging frame is arranged at the top of the box body, a material cavity is formed in the box body, the hanging frame is used for installing voltage, temperature and displacement measuring equipment, a sampling hole is formed in the front face of the material cavity, water-permeable isolation plates are arranged on the left and right sides, seepage water iscollected by a measuring cup, and electrode plates are inserted into the water-permeable isolation plates. The method comprises the following steps: 1, a gravity drainage experiment: preparing materials, assembling instruments, loading the materials, measuring the displacement, measuring the moisture content and cleaning the instruments; and 2, an electroosmosis drainage experiment; preparing materials, performing instrument assembly and material loading, performing displacement measurement, performing material horizontal and vertical displacement measurement, performing electrode plate electrification and material mass loss recording until electroosmosis drainage is finished, stopping the electrode plate electrification, recording the total electroosmosis drainage experiment duration, performing moisture content measurement, performing instrument cleaning, and repeating electroosmosis drainage experiments, wherein the difference is that the experiment end time point is randomly takenwithin the total electroosmosis drainage experiment duration range.

Description

technical field [0001] The invention belongs to the technical field of electroosmosis experiments, and in particular relates to a multifunctional electroosmosis experiment instrument and a using method thereof. Background technique [0002] my country has a large population and a great demand for land resources. With the gradual acceleration of the development of coastal cities, the urban economy has steadily improved, the urban population density is increasing, and there is a serious shortage of land resources. In order to cope with the population surge and land resources In order to solve the shortage problem, it is an inevitable result of urban development that coastal cities take advantage of the advantages of adjacent sea areas to carry out reclamation projects from the sea. Most of the land reclamation technologies currently used in my country are dredging reclamation methods, which require a large amount of soil, sand, stone and other materials during the land reclamat...

Problems solved by technology

[0009] From the previous discussion, it can be seen that the measurement of the change of electrode corrosion over time and the temporal and spatial evolution of water content should be an important function in the electroosmotic experimental equipment, but the existing related electroosmotic experimental equipment can only complete the displacement. The measurement of basic content such as voltage, current, etc., cannot measure the change of electrode corrosion over time and the temporal and spatial evolution of water content.

In addition, the reasons for the change of the water content of the test soil are that one is that the water in the electroosmosis seeps out from the negative electrode, and the other is that the evaporation loses water. However, the existing electroosmosis experimental equipment can only measure the water seepage of the electrode, and does not measure the evaporation. amount to measure
