STRUT WITH WEED LUXURIANT-GROWTH PREVENTIVE BOARD

摘要

PROBLEM TO BE SOLVED: To prevent the growth of weeds in the periphery of a strut by installing a weed luxuriant-growth preventive board, to which an inserting hole is formed, to a headband-shaped string-drawing-worked projecting lower section formed on a boundary between the underground buried section of the strut for a guard rail, etc., and a ground surface. SOLUTION: A string-drawing worked section 2 is prepared to a fixed outer circumferential surface section as a boundary between the underground buried section of a strut 1 and a ground surface section. The string-drawing worked section 2 is projected and formed from the fixed outer circumferential surface section of the strut 1 in an approximately elliptical shape, and mounted so that the inner circumferential section of the inside of the surface of the weed luxuriant-growth preventive board 5 is fast stuck approximately around the string-drawing worked section 2. A gentle downward inclination conducting throating work is formed from the inner circumferential section of the inside of the surface to the outer circumferential section of the outside in the weed luxuriant-growth preventive board 5. A protruded section, to which headband-shaped ring welding or screwing, etc., are executed, is formed to the strut 1, and the weed luxuriant-growth preventive board 5 may also be housed around a lower section. Accordingly, the growth of weeds in the periphery of the strut 1 is prevented, the usage of a mowing machine is obviated, and a road can be maintained and managed safely with excellent operating efficiency.
