INSTALLATION METHOD AND INSTALLATION STRUCTURE FOR DRIFTWOOD TRAP CONSTRUCTION
To provide an installation method and an installation structure for a driftwood trap construction that is extremely flexible to freely install driftwood that flows down a river according to the topography and properties of a sediment area and can be installed in an optimal location where countermeasures are required by configuring the driftwood trap construction installed in the sediment area with driftwood trap body of a self-supporting structure with each having an independent foundation.SOLUTION: A driftwood trap construction comprises multiple driftwood trap body 1 (11, 21). Each driftwood trap body 1 comprises a foundation 2 provided in a sediment area 10, and one or a plurality of driftwood trap pillar members 3 standing on the foundation 2. Each driftwood trap body 1 is installed so as to be independent and self-supported. According to the topography of the sediment area 10, the number of the driftwood trap bodies 1 and an installation place where the driftwood trap bodies 1 are suitable for trapping the driftwood flowing down the river are determined. The sizes of the foundation 2 and the driftwood trap pillar member 3 of the driftwood trap body 1 are appropriately adjusted and installed according to properties such as strength and height of the sediment area 10 at the installation place.SELECTED DRAWING: Figure 1
【課題】堆砂域に設置される流木捕捉工を、各々が独立した基礎を有して自立する構造の流木捕捉体で構成することにより、前記堆砂域の地形や性状に応じて河川を流下する流木を効果的に捕捉できる部位に自在に設置できる等、対策の必要な箇所に最適な配置で設置できる自在性に非常に優れた流木捕捉工の設置方法および設置構造を提供する。【解決手段】前記流木捕捉工は複数の流木捕捉体１（１１、２１）からなり、各流木捕捉体１は前記堆砂域１０に設ける基礎２と前記基礎２に立設される１本又は複数本の流木捕捉柱部材３とからなり、各々の流木捕捉体１を独立して自立する構成で設置する。前記堆砂域１０の地形に応じて河川を流下する流木を捕捉するのに適正な前記流木捕捉体１の個数と配置箇所を定めると共に、前記配置箇所の堆砂域１０の強度や高さ等の性状に応じて前記流木捕捉体１の前記基礎２および前記流木捕捉柱部材３の大きさを適宜調整して設置する。【選択図】図１
