METHOD FOR ELECTROOSMOTIC STABILIZATION OF GROUND AROUND FOUNDATION SUPPORTS OF TECHNOLOGICAL EQUIPMENT Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to strengthening of foundations. For realization of method, selected is group of foundations and supports relating wherever possible to single component of technological equipment. Installed between foundations of selected group of supports are anode electrodes. Cathode electrodes are located beyond preliminarily given zone of ground stabilization. This zone is preset proceeding from condition that it embraces selected group of foundations. Taken into consideration in determining extension of ground stabilization zone are such factors as distances between anode electrodes, cathode electrodes, foundations of supports, as well as sinking depths of electrodes. Anode electrodes are located with account of presence in ground of earlier sunken metal articles. In this case, metal articles positioned beyond ground stabilization zone are preliminarily connected with cathode electrodes. After installing electrodes and their connection to corresponding poles of source of electric current, undertaken is delivery of stabilizing solution into ground through electrodes simultaneously with passing current between electrodes. After preset period of time, delivery of stabilizing solution is discontinued. Application of aforesaid method allows for enhancing reliability in operation of key equipment and makes unnecessary disengagement of equipment during repair period. EFFECT: higher efficiency. 3 cl, 1 dwg
