DRIFTWOOD-TRAPPING BODY AND DRIFTWOOD-TRAPPING BODY CONSTRUCTION METHOD, AND DRIFTWOOD-TRAPPING FACILITY INSTALLATION STRUCTURE
To provide a driftwood-trapping body and its construction method, and a driftwood-trapping facility installation structure, which are applied upstream of a weir having a structure separated from the aforesaid weir and also from adjacent other driftwood-trapping bodies (with spaces between their bases), enabling reduction of the amount of concrete used and installation in optimum arrangements at spots where countermeasures are required, so that are superior in workability, economical efficiency and flexibility.SOLUTION: A driftwood-trapping body 1 is installed upstream of a sand-arrestation weir 10, and consists of: a member 2 forming a closed cross section; a filler member 3 filling the space of the aforesaid closed cross section; a pile foundation 4 which protrudes downwards from the aforesaid closed cross section space being fixed in the aforesaid filler member 3; and a driftwood-trapping column member 5 which stands being fixed in the aforesaid filler member 3. The aforesaid driftwood-trapping column member 5 stands being removably inserted into a sheath pipe 6 fixed in the aforesaid filler member 3.SELECTED DRAWING: Figure 2
【課題】堰堤の上流側に、前記堰堤とは切り離した構造で、かつ、隣接した流木捕捉体（の基礎同士）も切り離した構造で実施することにより、使用するコンクリート量を抑制でき、対策の必要な箇所に最適な配置で設置できる、施工性、経済性、及び自在性に優れた流木捕捉体および流木捕捉体の構築工法ならびに流木捕捉工の設置構造を提供する。【解決手段】砂防堰堤１０の上流側に設置される流木捕捉体１であって、前記流木捕捉体は１、閉断面空間を形成する閉断面形成部材２と、前記閉断面空間内に充填される中詰材３と、前記閉断面空間から下方に突出して前記中詰材３に固定される杭基礎４と、前記閉断面空間から立ち上がり前記中詰材３に固定される流木捕捉柱部材５とからなる。前記流木捕捉柱部材５は、前記閉断面空間内に設けられ前記中詰材３に固定される鞘管６内に脱着可能に挿入して立ち上がる構成である。【選択図】図２
