Problems solved by technology

[0004] (1) The transmission efficiency of the potential decreases. As the water in the soil near the anode migrates toward the cathode, the moisture content of the soil near the anode gradually decreases, the resistance gradually increases, and the anode is affected by corrosion, resulting in a significant potential drop. Only valid below 75% of rated voltage

Embodiment Construction

[0036] like figure 1 As shown, the enhanced electroosmosis system for strengthening soft clay foundation mainly includes vertical drainage components and horizontal drainage components. They are used to form a transverse electric field and a longitudinal electric field, respectively, so that the water is concentrated and discharged in a fixed direction.

[0037] The vertical drainage assembly includes a plurality of sets of vertical cathodes and vertical anodes arranged in the foundation, a first DC power supply electrically connected to the vertical cathodes and the vertical anodes, and one end extending to the vertical cathode and the other A drain pipe connected to the vacuum jet pump at one end; a horizontal electric field is formed between the vertical anode and the vertical cathode, and in the working state, the water is concentrated towards the vertical cathode;

[0038] A horizontal drainage assembly, more than two sets of horizontal electrodes arranged along the leng...

Abstract

The invention discloses a strengthening electro-osmosis method and system used for reinforcing a soft clay foundation. The method comprises the following steps that electrodes are vertically and horizontally driven into the soft clay foundation, by forming a horizontal electric field between the vertical electrodes and a vertical electric field between the horizontal electrodes, water in a soil body is transferred into a shallow soil body in a cathode area, and discharged in a vacuum-pumping way, and in the process that the vertical anodes are electrified, spraying humidification is conducted.By means of the method, the water converged at the cathodes can be effectively discharged out of the soil body, the service life of the electrodes is prolonged, the problems are solved that in a conventional electro-osmosis method, the soil body is not uniformly reinforced, and the anodes are corroded seriously, the operation is simple, the efficiency is high, and the cost is low.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and in particular relates to a strengthening electroosmosis method for strengthening soft clay foundations. Background technique [0002] When the cathode and anode electrodes are inserted into the soil and the DC power supply is connected, under the action of the electric field force of the power supply, the electrons from the negative pole of the power supply migrate to the cathode through the wire, and the electrons on the anode migrate to the positive pole of the power supply through the wire. The flow of electrons at the anode, the cathode must keep losing electrons, and the anode must keep gaining electrons. Since electrons cannot directly enter the aqueous solution in the soil from the cathode to the anode, a reduction reaction that consumes electrons occurs at the interface between the cathode and the aqueous solution, and an oxidation reaction that generates electrons occurs at th...
