WEED-PROOF STRUCTURE, CEMENT CONCRETE CURB STONE AND WEED-PROOF PLATE

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive weed-proof structure capable of efficiently preventing grassing between a cement concrete curb stone and a pavement material.SOLUTION: In a weed-proof structure 1, a weed-proof plate 4 is installed between a cement concrete curb stone 2 and a pavement material 3. The weed-proof plate 4 is made of a metal plate containing zinc or aluminium as a main component or a metal plate on which a coating layer containing zinc or aluminium as a main component is formed. The pavement material 3 is cement concrete or asphalt concrete. The surface of the curb stone 2 and the weed-proof plate 4 are disposed in parallel. The weed-proof plate 4 is installed below the pavement material 5 in the weed-proof structure 1.SELECTED DRAWING: Figure 1
