流木捕捉工の設置方法および設置構造
Document Type and Number:
Japanese Patent JP7251974
Kind Code:
B2
Abstract:
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
