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

[0037] The vertical drainage assembly includes multiple sets of vertical cathodes and multiple sets of vertical anodes arranged in the foundation, a first DC power supply electrically connected to the vertical cathodes and vertical anodes, and one end extending to the vertical cathodes 1. The drain pipe connected to the vacuum jet pump at the other end; a horizontal electric field is formed between the vertical anode and the vertical cathode, and the water is concentrated toward the vertical cathode in the working state;

[0038] Horizontal drainage assembly, more than two groups of horizontal electrodes arranged along th...

Abstract

The invention discloses an enhanced electroosmosis system and method for strengthening soft clay foundations, comprising the following steps: driving electrodes vertically and horizontally into soft clay foundations, forming a horizontal electric field between the vertical electrodes, and forming a horizontal electric field between the horizontal electrodes. A vertical electric field is formed between them, and the water in the soil is moved to the shallow soil in the cathode area, and the water is discharged by vacuuming, and the spray humidification treatment is carried out during the vertical anode electrification process. The invention can effectively discharge the water gathered at the cathode from the soil, prolong the service life of the electrode, solve the problems of uneven soil reinforcement and serious corrosion of the anode by the conventional electroosmosis method, and is easy to operate, high in efficiency and low in cost.

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 foundation. 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 on the negative pole of the power supply migrate to the cathode through the wire, and at the same time, the electrons on the anode migrate to the positive pole of the power supply through the wire. For the flow of electrons at the anode, the cathode must constantly lose electrons, while the anode must constantly gain electrons. Since electrons cannot directly enter the aqueous solution in the soil from the cathode to reach the anode, a reduction reaction that consumes electrons occurs at the interface between the cathode and the aqueous solution, and an oxidation reaction tha...
