用自在開閉扉。The main door hangs in close contact with the board without any gaps in front of the main opening of the drain in the embankment, so that it is pushed diagonally forward and open only when the main door is pushed strongly by the water force of the drainage channel. The main door is pivoted to the main door, a sub-opening is provided in a part of the main door, and a bracket is installed above the sub-opening to protrude forward higher than the center of gravity of the sub-door. The above-mentioned bracket is a sub-door that has a bracket protruding forward at the same height at the upper end of the body, a connecting rod between both brackets, and a sub-opening closed at the lower end of the bracket. A sub-door is a sub-door whose body is suspended and fixed in a swingable manner, and the sub-gate body of the sub-door is connected to the pivot point at the upper and lower ends of the connecting rod and the sliding contact point on the back surface of the upper end of the sub-door body, and the lower end of the sub-door body is A freely opening/closing door for an in-bank drainage outlet characterized by being supported at three points so as to open forward at a predetermined angle of inclination.
