PROBLEM TO BE SOLVED: To avoid danger into which a person might fall, even when the person should by any chance tumble over an area near a line of concrete blocks which are used as a slide wall for repelling centipedes, while the slide wall is structured based on an earlier idea of repelling the centipede by attacking a weak point of a multiped organism, so as to completely surround a house with single-stage concrete blocks having a unique shape in such a manner as if the Great Wall of China does and to adhere polymer tubes as a slide material to the blocks. SOLUTION: This slide wall 1 is so structured that its material is changed into a plastic from concrete earlier used, so as to avoid the danger, and the material itself constitutes the slide wall 1. Although the material is made to be lightweight, the slide wall is prevented from being blown away by a strong wind, by forming an upper space of an inner hollow 2 of a wall body of the slide wall 1 into a hole 3 and inserting an iron bar into the hole 3. On the other hand, the whole slide wall is disassembled, removed, and stored in a shed, or the like, in seasons other than summer, in which the slide wall is not required, as a result of being made to be lightweight. Further, the material which is made of the plastic is not corroded, and the iron bar which is used as a weight and kept in the hollow 2 is not wetted by rain water and therefore is prevented from rusting, so that the slide wall is repeatedly used year by year.
