CHAMFERED MEMBER
To provide a chamfered member that can reduce the load at the start of pulling because the buoyancy acts strongly on the chamfered member itself, and can be floated easily by crushing sediment even when sediment is accumulated on an upstream side.SOLUTION: A three-dimensional float 2 in which one surface 2a faces an upstream side of a flow channel and the other surface 2b faces a downstream side of the flow channel, and a space S is formed inside, first passage portions 3, 3 which are perforated on one surface 2a and through which water passes, second passage portions 4, 4 which are perforated on the other surface 2b and through which water passes, and third passage portions 5, 5 which are perforated on a ceiling-side surface 2c of the float 2 and through which air and water pass, are provided. First to third opening and closing members 6 to 8 are attached to the first to third passage portions 3 to 5, respectively.SELECTED DRAWING: Figure 1
【課題】角落し材自体に浮力が強く作用することで、引き上げ開始時に負荷を軽減できるとともに、上流側に土砂が堆積している場合にも、土砂を崩すことで容易に浮上させることが可能な角落し材を提供する。【解決手段】一方の面２ａが流路の上流側に対向し、かつ他方の面２ｂが流路の下流側に対向するとともに、内部に空間Ｓが形成される立体形状のフロート２と、一方の面２ａに穿設され水が通過する第１の通過部３，３と、他方の面２ｂに穿設され水が通過する第２の通過部４，４と、フロート２の天井側の面２ｃに穿設され、空気及び水が通過する第３の通過部５，５を備え、第１乃至第３の通過部３〜５は、それぞれ第１乃至第３の開閉部材６〜８が取り付けられる。【選択図】図１
