DITCH COVER APPROPRIATE FOR WATERWAY CROSSING SLOPE FACE
PROBLEM TO BE SOLVED: To provide a ditch cover appropriate for a waterway crossing a slope face.SOLUTION: A ditch cover made of a metal plate for covering an area from an upper end of one side wall of an open channel-type waterway to upper end of the other side wall is formed so that its center can become higher in a longitudinal direction. On the one slope, a large number of small scales in a state, in which three sides, that is, right, lower, and left sides are cut open in a U-shape in a front view of the slope and in which the upper side is raised by being bent in a front-side direction, are arranged at intervals in a longitudinal direction of the slope. Many small through-holes are arranged at intervals on at least the other slope.SELECTED DRAWING: Figure 1
【課題】 斜面を横断する水路に適した溝蓋の提供。【解決手段】 開渠型水路の一方の側壁上端から他方の側壁上端までを覆う金属板製の溝蓋は、その中央が長手方向に渡って高くなるよう形成されており、その一方の斜面には、斜面を正面視して右辺下辺左辺の３方がＵ字状に切開され上辺が表方向に折曲げ起こされた状態の小鱗片が、斜面長手方向に間隔を離間して多数配されており、多数の貫通小孔が少なくとも他方の斜面に間隔を空けて配されていること、を特徴とする溝蓋である。【選択図】 図１
