DRIFT WOOD CAPTURING STRUCTURE
To provide a drift wood capturing structure capable of highly improving drift wood capturing effect without changing a height of the drift wood capturing structure body (steel column member) through additionally arranging a drift wood overflow suppressing member as an auxiliary member to the steel column member (drift wood capturing column).SOLUTION: A drift wood capturing structure is provided with a plurality of steel column members 1 arranged apart to each other in a direction across a river, wherein the steel column member 1 comprises at least one drift wood capturing column 2 and a drift wood overflow suppressing member 8 is arranged on an upper part of the drift wood capturing column 2 in a way that a height thereof is higher than that of a top end of the drift wood capturing column 2 by extruding to an upper stream side U. The height of the drift wood overflow suppressing member 8 is arranged equal to or twice higher than an estimated maximum drift wood diameter and lower than 50 cm from the top end of the drift wood capturing column 2.SELECTED DRAWING: Figure 3
【課題】鋼製柱部材（流木捕捉支柱）に流木越流抑制部材を補助部材として付設することにより、流木捕捉工の本体（鋼製柱部材）の高さをそのまま変えることなく、流木の捕捉効果を飛躍的に高めることができる流木捕捉工を提供する。【解決手段】鋼製柱部材１を河川横断方向に間隔をあけて複数設置してなる流木捕捉工であって、鋼製柱部材１は、少なくとも１本の流木捕捉支柱２からなり、流木捕捉支柱２の上部に、流木越流抑制部材８が、流木捕捉支柱２の天端よりも高くなるように上流側Ｕへ突き出して設けられて成る。流木越流抑制部材８が、流木捕捉支柱２の天端よりも、想定される最大流木径の２倍以上、５０ｃｍ未満の範囲内で高く設けられている。【選択図】図３
