To provide an installation method for a weed-proof sheet having a structure in which a gap (H1) of an air reservoir is eliminated and a filler such as an adhesive is not injected, and to provide its structure, thus, at the time of backfill, a repairing material can be filled surely, and in addition, in rolling work, the inverted V-shaped weed-proof sheet is embedded in an inverted V-shaped cut groove for weed-proofing without gaps.SOLUTION: In an installation method for a weed-proof sheet, cut grooves for weed-proofing of a joint of a road, a concrete of a road, a block, etc., are formed in a single row in a traveling direction and in a double row in a direction orthogonal to the traveling direction; and cut grooves are in an inverted V-shape, and the weed-proof sheet in an inverted V-shape which is bent from a flat to form an inverted V-shape along the inverted V-shaped groove is covered or spread. At the time of backfill, a repairing material can be reliably filled. In a rolling work, the inverted V-shaped cut grooves for weed-proofing sheet can be embedded with the inverted V-shaped weed-proof sheet without gaps.SELECTED DRAWING: Figure 3-2 【課題】本発明は、従来の課題である。空気溜りの隙間（Ｈ１）を無くし、接着剤等の充填剤を注入しない構造の防草シートの設置方法と、その構造を提供する。これにより、埋め戻し時において、補修材を確実に充填できる。また、転圧作業で、防草用の倒Ｖ字形の切込み溝に、倒Ｖ字形の防草シートを、隙間なく埋設する。【解決手段】道路の目地、道路のコンクリート、ブロック等の防草用の切込み溝であって、切込み溝は、走行方向に単列・走行方向の直交方向に複列かに形成し、そして、切込み溝は、倒Ｖを呈しており、倒Ｖに添うようにして、フラットから折り曲げて倒Ｖ字形とした、倒Ｖ字形の防草シートを包被、又は展着する防草シートの設置方法。埋め戻し時において、補修材を確実に充填できる。転圧作業で、防草用の倒Ｖ字形の切込み溝に、倒Ｖ字形の防草シートを、隙間なく埋設できる。【選択図】 図３−２
