<p>AN APPARATUS AND METHOD OF ASSISTING PILE DRIVING BY ELECTRO-OSMOSIS An apparatus and method of assisting the driving of a pile into soil containing water by electro-osmosis in which electrical direct current is directed through the soil for reducing friction between the pile and the soil allowing the pile to be more easily driven through the soil. An electrically conductive base is connected to the bottom of the pile and an insulated electrical conductor is connected between the d-c power source and the conductive base. A second electrical conductor is connected to the power source and terminates at a position spaced from but in electrical communication through the soil with the base whereby passage of electrical current between the base and the second electrical conductor reduces friction between the pile and the soil. If the pile is electrically conductive, the conductive base is electrically insulated from the pile in order to direct current through the soil adjacent the base. The second electrical conductor may be connected to the pile if the pile is conductive or in the soil or in water covering the soil. After the pile has been driven, the electrical current may be directed through the soil adjacent the pile to dry the soil thereby increasing the load bearing strength of the soil.</p> |
