摘要
To provide an acidic water drainage structure in a sloped face which can properly drain acidic water in a sloped face and is easily applied.SOLUTION: A quadrangular frame-shaped slope frame 1 is disposed in a grid-shape on a sloped face 101. A drain hole 11a is formed in a lateral frame portion 11 extending in a lateral direction of the slope frame 1. The vertically adjacent drain holes 11a of the lateral frame portion 11 are connected with each other by a water collecting and draining material 4 arranged in an inside 1a of the slope frame, being long and having water collecting and draining property. A belt-shaped water permeable mat 32 having water permeability is arranged downwardly from an acidic water deposition position in the inside 1a of the slope frame toward the water collecting and draining material 4. The acidic water W deposited from the acidic water deposition position is collected into the water collecting and draining material 4 via the water permeable mat 32, and flows downward through the drain holes 11a.SELECTED DRAWING: Figure 1
