description The invention discloses a method for laying bottom bricks in blast furnace maintenance, and belongs to the technical field of blast furnace equipment maintenance. The method comprises the following steps: firstly, erecting a protection shed in the middle of a blast furnace, arranging an electric hoist below the protection shed, then arranging a brick inlet gate on a cooling wall below the protection shed, erecting a horizontal steel platform outside the brick inlet gate in the mode of extending into the furnace, then transferring various bottom bricks into the furnace through a transport channel and the electric hoist below the protection shed, transferring the bottom bricks layer by layer and laying the bottom bricks layer by layer until all the bottom bricks are built, finally, dismantling the protection shed and the transport channel, and plugging the brick inlet gate and other holes in the cooling wall. The protection shed is erected in the middle of the blast furnace, bottom bricklaying and upper furnace
