INSTALLATION STRUCTURE FOR DRIFTING WOOD CATCHING BODY
To provide an installation structure for drifting wood catching body in which there is of course no need of large-scale work such as notching or rising a check dam 10, and that does not require a concrete foundation by realizing a structure that can support a drifting wood catching body 1 in a cantilevered state only by using the check dam 10, and that is superior in workability, economic efficiency and stability.SOLUTION: The present invention is an installation structure for a drifting wood catching body 1 with respect to a check dam 10, the installation structure being provided with a plurality of steel column members 2 each provided so as to project in a cantilevered state via a base member 3 that protrudes from an upstream lateral surface part of the check dam to the upstream side. As an example, the steel column member 2 is formed of the heads of a drifting wood catching prop (upstream vertical member) 2a and a downstream support prop (diagonal member) 2b that slopes forward on the upstream side being integrated by means of welding, the steel column member 2 being formed in an inverted U shape that opens toward the flowing direction of a river.SELECTED DRAWING: Figure 1
【課題】前記砂防堰堤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を砂防堰堤１０だけで片持ち状態で支持可能な構造を実現することにより、コンクリート基礎を無用化し、施工性、経済性、及び安定性に優れた流木捕捉工の設置構造を提供する。【解決手段】砂防堰堤１０に対する流木捕捉工１の設置構造であって、複数の鋼製柱部材２がそれぞれ、前記砂防堰堤の上流側側面部から上流側へ突き出した土台部材３を介して片持ち状態で張り出して設けられて構成されている。前記鋼製柱部材２は、一例として、流木捕捉支柱（上流側鉛直材）２ａと、上流側へ前傾させた下流側支え支柱（斜材）２ｂとが頭部同士を溶接により一体化されて河川の流れ方向に開脚する倒立レの字状に形成されている。【選択図】図１
