Abstract

The present invention relates to a method for inducing ground consolidation. The method comprises providing a first chamber (7) in a first hole (3) in the ground (5), and a second chamber (7) in a second hole (3) in the ground (5), the first and second chambers (7) being liquid-impermeable and electrically conductive; providing a first electrolytic fluid in the first chamber (7) and a second electrolytic fluid in the second chamber (7); placing at least a first electrode (9) in the first chamber (7), and at least a second electrode (9) in the second chamber (7), the first and second electrodes (9) being operatively connected to a power supply (25); feeding consolidation fluids into the ground for feeding reactants of a consolidation process, and catalysers for the reactants into the ground; and applying to the first and second electrodes (9) an electric current. The current causes the first electrode to operate as an anode and the second electrode to operate as a cathode thereby inducing electric polarisation in the ground to cause the reactants and catalysers to cross paths to thereby cause consolidation of the ground (5).

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell.

Reference electrode

A reference electrode is an electrode that has a stable and well-known electrode potential. The overall chemical reaction taking place in a cell is made up of two independent half-reactions, which describe chemical changes at the two electrodes. To focus on the reaction at the working electrode, the reference electrode is standardized with constant (buffered or saturated) concentrations of each participant of the redox reaction. There are many ways reference electrodes are used.

Electric current

An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. In electric circuits the charge carriers are often electrons moving through a wire. In semiconductors they can be electrons or holes.
