The invention provides clearing and conveying equipment for filling materials in large-scale tower equipment. The clearing and conveying equipment comprises a filling material slideway plate, a funnel, a passage and a collecting disc, wherein the filling material slideway plate is in inclined arrangement; a feeding opening of the funnel is positioned right under the lower end of the filling material slideway plate; the passage is in inclined arrangement and comprises an outer tube and an inner tube made of an elastic mesh plate; the inner tube is positioned in the outer tube; the outer wall bottom surface of the inner tube and the inner wall bottom surface of the outer tube form an attachment article passage; the collecting disc is positioned under an attachment passage outlet; the feedingopening of the inner tube is positioned right under the discharging opening of the funnel. The equipment has the advantages that the environment pollution can be avoided; the filling material replacing efficiency can be improved; the quality of the reused filling materials can be ensured. The invention also provides a replacing construction method for filling materials in the large-scale tower equipment. The method has the advantages that the pouring of filling materials at each layer in a tower on the ground can be avoided; the environment pollution is reduced; the construction cost can be reduced; the labor work intensity is high; the construction efficiency is improved.
