PROBLEM TO BE SOLVED: To provide a permeable-type check dam which is structurally simple, which makes a construction cost low, and which exerts durability even when a large-scale debris flow occurs.SOLUTION: A permeable-type check dam includes: a plurality of front steel pipes 3 that are driven at predetermined intervals on an upstream side between sleeve parts 2 and 2; a plurality of rear steel pipes 5 that are driven at predetermined intervals on a downstream side between the sleeve parts; and a connection member 7 for connecting the plurality of front steel pipes and the plurality of rear steel pipes together. The connection member constitutes a truss structure.SELECTED DRAWING: Figure 1 |
