INSTALLATION STRUCTURE FOR DRIFTING WOOD CATCHING BODY
To provide an installation structure for drifting wood catching body that not only needs no large-scale work such as notching or raising a check dam 10, but also has higher flexibility in an installation form of a drifting wood catching body 1 and a degree of freedom of design (plenty of variations), as well as capability of effectively catching flowing objects such as drifting wood.SOLUTION: The drifting wood catching body 1 comprises: two or more steel column members 2 provided in a balanced manner in a front direction upstream from a water passage 11 of a check dam 10; two or more steel column members 3 (3a, 3b) each provided in a front direction upstream from lateral parts 12, 12 of the check dam 10; and a foundation member 4 supporting the steel column members 2, 3. Each of the steel column members 2, 3 comprises: at least one prop 7,17, and the two or more steel column members 3 (3a, 3b) each provided on the lateral part 12, 12 sides have sizes and arrangement suitable for catching drifting wood that flows down on the widthwise ends of a river.SELECTED DRAWING: Figure 1
【課題】砂防堰堤１０を切欠き又は嵩上げする等の大掛かりな作業の必要性がないことはもとより、流木捕捉工１の設置形態について、より自在性、柔軟性が高く、設計の自由度（バリエーション）に富み、流木等の流下物を効果的に捕捉できる流木捕捉工の設置構造を提供する。【解決手段】前記流木捕捉工１は、前記砂防堰堤１０の水通し部１１の上流側正面方向にバランスよく設けられる２以上の鋼製柱部材２と、前記砂防堰堤１０の両袖部１２、１２の上流側正面方向にそれぞれ設けられる２以上の鋼製柱部材３（３ａ、３ｂ）と、前記鋼製柱部材２、３を支持する基礎部材４とから成る。前記鋼製柱部材２、３は、少なくとも１本の流木捕捉支柱７、１７からなる構成で、前記両袖部１２、１２側にそれぞれ設けられる前記２以上の鋼製柱部材３（３ａ、３ｂ）は、河川の幅方向端部を流下する流木を捕捉するのに適正な大きさ及び配置とされている。【選択図】図１
