The invention discloses an online repairing method for the side part of an aluminum electrolysis cell. The online repairing method comprises the following steps: determining the repairing position of the side part, sinking an anode group into the bottom of the cell in a power-off manner, isolating liquid, determining a treatment mode, repairing a damaged part, roasting at low temperature, returning anodes and cleaning materials. According to the method, the damaged side part of the aluminum electrolysis cell can be quickly repaired under the conditions of no interruption of the cell and no power failure, and side part cell leakage and other safety risks are reduced; the local damaged side part is repaired, so that the horizontal current is reduced, the operation stability of the electrolytic cell is improved, and the service life of the cell is prolonged; and after repairing, the daily inspection and data measurement frequency of workers is reduced, emergency treatment when the temperature of the side wall is
