PROBLEM TO BE SOLVED: To provide a roadside installation type snow prevention fence capable of exhibiting a high blowing-off function by downwardly guiding even a snowstorm from the right-angled direction and the oblique direction of any of the left and right to a road, making the snowstorm merge with a snowstorm flowing near the ground surface, and compounding them into high wind pressure, and capable of also efficiently executing work, since a column does not become a hindrance in snowplow.SOLUTION: A pair of columns 2 and 2 are erected on the ground G along the roadside. Support materials 3, 5 and 4 whose length gradually increase from the upper side to the lower side are provided to the respective columns 2, projecting to the road side. Upper, lower and intermediate respective horizontal connection materials 6, 7 and 8 are installed between the respective pairs of support materials 3, 3 (5, 5, 4 and 4). A snow prevention plate 9 of a concave curved shape on a reverse surface 9B is fastened to the respective horizontal connection materials 6, 7 and 8 in a longitudinally long state, and is provided in a row in the horizontal direction between the columns 2 and 2. The respective snow prevention plates 9 are put in an oblique downward state on the reverse surface 9B at an inclination angle within about 20 degrees to a vertical line, and the snow prevention plates 9 are formed with a clearance to be a blow-by space S between the ground G and itself. |
