摘要： PROBLEM TO BE SOLVED: To store rainwater even when an infiltration pipe is set in the ground of a geological feature having a slow infiltration speed of rainwater or the quantity of the rainwater flowing into the infiltration pipe is small, and enhance the infiltration efficiency by providing a weir for regulating the level of the water passing in an U-shaped open channel. SOLUTION: In an U-shaped open channel 1 forming an infiltration open channel to be set in the ground, an infiltration port 1b having a filter 2 for filtering rainwater is formed in a prescribed position of its side wall 1a, so that rainwater is infiltrated into the ground. A weir 3 lower by a prescribed dimension from a top board 1d is provided in the space by both side walls 1a and bottom board 1c of the U-shaped open channel 1 on the upstream or downstream end part inside of the U-shaped open channel 1. By providing the weir 3, the water passing in the box culvert 1 can be stopped and stored with the level being regulated to delay the outflow time of rainwater. Accordingly, even when the open channel is set in the ground of a geological feature having a slow infiltration speed, or the inflow quantity of rainwater is small, the rainwater can be stored to improve the infiltration efficiency.
