Abstract

Provided is a method for repairing a coke oven by replacing, in a hot condition, bricks of one combustion chamber that compose the coke oven or bricks of a plurality of continuous combustion chambers that compose the coke oven with two or more oven wall bricks and binder bricks along an oven longitudinal direction from an oven mouth. This method includes: a confirmation step in which a three-dimensional measurement device is used to observe, from the oven mouth, concavity and convexity of an oven wall of a neighboring non-replacement target combustion chamber that is adjacent to one side surface of one replacement target combustion chamber or a plurality of continuous replacement target combustion chambers, and concavity and convexity of an oven wall of a neighboring non-replacement target combustion chamber that is adjacent to the other side surface of the one replacement target combustion chamber or plurality of continuous replacement target combustion chambers, thereby confirming that bulging amounts of the oven walls of the neighboring non-replacement target combustion chambers are each smaller than a given value; and a replacement step in which when the bulging amounts of the oven walls of the neighboring non-replacement target combustion chambers have each been confirmed to be smaller than the given value in the confirmation step, a portion of an oven wall of the one replacement target combustion chamber or plurality of continuous replacement target combustion chambers, which requires repair, is dismantled, followed by newly stacking oven wall bricks and binder bricks in the dismantled area.
