Electroosmosis electrode and mounting mode

Abstract

The invention discloses an electroosmosis electrode and a mounting mode. The electroosmosis electrode on the same metal pipe is divided into a connecting exhausting section, an insulating section and an open pore processing section from up down in sequence; wire connecting pores and water and air discharging pores are distributed on the connecting exhausting section; the outside of the insulating section is coated with insulating varnish; water discharging pores are distributed on the open pore processing section densely; the top of the connecting exhausting section is provided with a plastic cap and the bottom thereof is provided with metal shoes. When mounting, the top end of the insulating section is required to be higher than the ground, the bottom end thereof is required to be deeper than the bottom of soil layer good in water permeability; adjacent four electroosmosis electrodes are mounted in rectangle shape, and the distance between electrodes with similar polarities is shorter than that between electrodes with opposite polarities; intermediate water discharging electroosmosis electrodes are inserted between the adjacent four electroosmosis electrodes; anode electroosmosis electrodes and cathode electroosmosis electrodes are respectively connected with the anode and cathode of DC power source. The invention can cause electroosmosis processing efficiency to be enhanced and the effect to be uniform, and is economic and efficient under condition of complicated stratum.

Description

technical field [0001] The invention relates to a foundation treatment device and its method, more specifically, the invention relates to an electroosmosis electrode and its installation method for improving the effect of electroosmosis treatment of soft soil under complex formation conditions. Background technique [0002] Unlike traditional drainage methods (such as well point method and preloading method), electroosmotic drainage has nothing to do with the pore properties of the soil, so it has been widely used in coastal reclamation and port construction in recent years. At present, the commonly used electrode materials and forms in engineering are steel bars as anodes and perforated steel pipes as cathodes, and the anodes and cathodes are installed in pairs and rows. [0003] This type of electrode has low cost and is easy to install, but it also has many shortcomings. When the soft soil layer to be treated is covered with a sand layer or silt layer with good water per...

[0003] This form of electrode is low in cost and easy to install, but it also has many shortcomings

When the soft soil layer to be treated is covered with a sand layer or silt layer with good water permeability, the pore water makes the electroosmotic circuit easy to short circuit, which may cause damage to the equipment or casualties; the electrode conversion technology can make the electroosmotic treatment effect in The plane is more uniform, but the different structures of the anode and the cathode hinder the application of this technology; the electrode reaction will generate gas around the electrode, and the airtightness of the anode prevents the gas from being discharged in time, and the contact resistance between the electrode and the soil It is very large, and the electroosmosis efficiency is low; the soil in coastal areas generally contains salt, and the electrode spacing is often increased to eliminate the impact of excessive current, but this reduces the electroosmosis drainage capacity, which in turn leads to a gap between the two electrodes after the electroosmosis ends. The moisture content of the soil is the highest; the initial bearing capacity of the electroosmotic treatment object is very low, and the installation of the electrodes is mostly done manually. If there is a hard soil layer, it is difficult for the electrodes to penetrate
