Abstract The present invention relates to a connection device for a corrugated steel pipe. Stoppers each comprise: a stopper body fixed while surrounding an end of a corrugated steel pipe; and a stopper protrusion protruding from an outer periphery of the stopper body along a circumferential direction. Watertight sleeves are disposed close to the end of the corrugated steel pipe, and the watertight sleeves each are formed to surround and fit the end of the corresponding corrugated steel pipe together with the outer periphery of the corresponding stopper body. Rotating flanges each comprise: a flange body disposed close to the center of the corresponding corrugated steel pipe and formed to surround the outer periphery of the corresponding stopper body with both ends spaced apart from each other; fixing pieces extending to face each other at opposite ends of the flange body and tightened by a fixing piece fastener; and angles protruding from the outside of the flange body. An angle fastener is fastened to an angle of one rotating flange and an angle of the other rotating flange, and thus, as the rotating flanges are tightened, the watertight sleeves are fixed in close contact with each other. According to the present invention, corrugated steel pipes can be easily and conveniently connected to each other. 본 발명은 파형강관 연결장치에 관한 것이다. 스토퍼들은 해당 파형강관의 단부를 감싼 상태로 고정된 스토퍼 몸체와, 스토퍼 몸체의 외주 부위로부터 둘레 방향을 따라 돌출된 스토퍼 돌기를 각각 구비한다. 수밀 슬리브들은 해당 파형강관의 단부 쪽에 가깝게 배치되어 해당 스토퍼 몸체의 외주 부위와 함께 해당 파형강관의 단부를 감싸서 끼우도록 각각 형성된다. 회전형 플랜지들은 해당 파형강관의 중앙 쪽에 가깝게 배치되어 양단이 이격된 상태로 해당 스토퍼 몸체의 외주 부위를 감싸도록 형성된 플랜지 몸체와, 플랜지 몸체의 양단에 각각 서로 마주하도록 연장되어 고정편 체결기구에 의해 조여지는 고정편들, 및 플랜지 몸체의 외측으로부터 돌출된 앵글들을 각각 구비한다. 앵글 체결기구는 한쪽 회전형 플랜지의 앵글과 다른 쪽 회전형 플랜지의 앵글에 체결되어 회전형 플랜지들을 조임에 따라 수밀 슬리브들을 서로 밀착시켜 고정한다.
