ROADSIDE INSTALLATION TYPE SNOW PREVENTION FENCE
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.
【課題】道路に対して直角方向及び左右いずれの斜め方向からの吹雪も下方に誘導して地表近くを流れる吹雪と合流させて高い風圧に合成することで高い吹払い機能を発揮することができ、また支柱が除雪作業時の障害にならないので効率的に作業を行うことができる路側設置型防雪柵を提供する。【解決手段】路側に沿って地盤Ｇに一対の支柱２、２を立設する。各支柱２に上から下にかけて次第に長さの長い支持材３、５、４が道路側に突設してある。各一対の支持材３、３（５、５、４、４）間に上部、下部、中間の各横連結材６、７、８が架設してある。裏面９Ｂが凹湾曲状の防雪板９は、各横連結材６、７、８に縦長の状態で締着して支柱２、２間に横方向に列設してある。各防雪板９は鉛直線に対して約２０度以内の傾斜角で裏面９Ｂを斜め下向きの状態にしてあり、かつ防雪板９は地盤Ｇとの間に吹抜け空間Ｓとなる間隙が形成してある。【選択図】図４
