WEED-PROOF COLLAR AROUND STRUT INSTALLED ON WEEDED GROUND
To address the problem in which various struts such as road signs, power poles, advertisement or beast guard fences are installed on a road shoulder, a surface of slope of various roads or a weeded ground of outer peripheral surface of a firm land, and weeds grow in contact with the outer front face of such struts and are removed by cutting by hand or a bush cutter; among others, the cutting by hand requires large amount of human fatigue or working time, whereas the bush cutter requires caution due to cutting near the strut front face, resulting in loss due to the recovery and repair of, such as, mental fatigue, breakage of the strut, deficit of cutting blade, etc.SOLUTION: A weed-proof collar of various strut installed in weeded ground is provided. The weed-proof collar has a dish-shaped depression concave downward, a dish-shaped outer peripheral circle with a diameter ranging from 4 cm for a small-diameter strut to 20 cm for a large diameter strut in the radial direction of the front face of each strut. The depth of the dish-shaped depression is 0.5 to 3 cm in the vicinity of the outer front face of each strut. Furthermore, the gradient from the dish-shaped convex surface outer periphery to the center is, in a range in the order of 1 to 3 cm from the outer edge or horizontal, parallel or low such as at about 15°. Furthermore, a half-width dividing type or dual-partitioning type of weed-proof collar is also proposed.SELECTED DRAWING: Figure 1
【課題】本発明は、各種道路の路肩、法面或は農耕地の外周面の雑草地に、道路標識、電柱、広告或は野獣防護柵等の各種支柱が設置されているが、それら支柱の外表面に接して成長しこれらを手刈り或は刈払機で除去等行っている。この際手刈りは人的疲労が大きく又作業時間を要している。他方刈払機の場合では支柱表面の近くを刈払う為注意が必要で精神的疲労と、支柱の折損、刈刃の欠損等復旧、修復に損失を生じている。【解決手段】皿状の窪みを下向きに凹として、皿状外周円の直径は、各種支柱の表面より半径方向に小径の支柱にて4cm、大径にて20cm程度の巾を持たせた直径として、皿状の窪みの深さは各種支柱の外表面近辺にて0.5〜3cmとし、更に皿状凸面外周から中心へ向う勾配は外縁から1〜3cm程度の間は水平ないしは15°程度の低勾配により構成される、雑草地に設置される各種支柱の防草鍔更に、防草鍔の片巾分割型と二分割型を提案する。【選択図】図１
