Title:
捕捉体の設置方法及び堰堤構造物
Document Type and Number:
Japanese Patent JP6785056
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an installation method of a capturing body capable of effectively installing a capturing body without modifying an existing weir while saving the cost and time required for construction.SOLUTION: In the installation method of a capturing body, which has a water passing part (21) through which water runs, a capturing body (3) is installed in a sweep area where sediment has accumulated at the upstream side of a river near a weir (2) for capturing drift woods flown down from the upstream of the river. Defining the distance from the water passing part to the capturing body in a flowing direction of the river as L1, the length of drift woods as L and the movement limit particle size as D, the capturing body is installed at a position facing the full length of the opening of the water passing part in the accumulated sediment (S) at the upstream side of the weir so as to satisfy the relationship in a formula (1) below: 2×D≤L1≤1/2×L (1).SELECTED DRAWING: Figure 1
