Zusammenfassung:The present invention relates to an odor blocking device for a manhole. The odor blocking device comprises: a drainage guide pipe which is tightly coupled to an upper part of a through hole penetrated on the bottom surface of a manhole to protrude upward by a predetermined length; and a lifting and blocking unit which is installed to surround the circumference of the upper end of the drainage guide pipe and to selectively ascend, so as to allow a lower end to be selectively attached to the bottom surface of the manhole. Drainage is conveniently performed toward a drain pipe communicated with and connected to a through hole penetrated through a bottom surface. At the same time, an ascending blocking unit blocks a backflow of odors of a drainage pipe by a water level when the water level in a manhole is equal to or greater than the height of the upper end of a drainage guide pipe. When the water level in the manhole becomes the same as a bottom surface, the ascending blocking unit descends, and the lower end is attached to the bottom surface of the manhole. Thus, it is possible to block a backflow of odors to the ground from the upper end of the drainage pipe. 본 발명은 맨홀용 악취차단장치에 관한 것으로, 본 발명은 맨홀의 바닥면 상에 관통된 통공 상부에 상향 일정길이 돌출되게 긴밀하게 결합되는 배수 안내관 및 상기 배수 안내관의 상단부 둘레를 감싸되 선택적으로 승강토록 설치되어 하단이 선택적으로 맨홀의 바닥면 상에 밀착되는 승강 차단유닛이 적용됨으로써 바닥면 상에 관통된 통공에 연통연결되는 하수관 측으로 배수가 간편하게 이루어짐과 동시에, 승강 차단유닛이 맨홀 내부의 수위가 배수 안내관 상단 높이 이상인 경우 수위에 의해 하수관의 악취 역류가 차단되며 맨홀 내부의 수위가 바닥면과 동일하게 되면 승강 차단유닛이 하강하여 하단이 맨홀 바닥면에 밀착되면서 하수관 상단으로부터 지상으로 악취가 역류하는 현상을 차단할 수 있는 것이다.
