In such a conventional wastewater or manhole structure, since the odor prevention trap adopts only a structure that prevents the backflow of the odor temporarily stored in the body portion, there is a problem that the odor prevention trap is clogged when a large foreign matter is caught in the bending portion . The clogging of the odor prevention trap obstructs the smooth flow of the sewage and causes the reverse flow phenomenon.

In order to solve such a problem, the manager takes the trouble of separating and cleaning the odor prevention trap from the body part into the inside of the sewer or manhole every time the odor prevention trap is blocked.

Particularly, in summer, there is a problem that a safety accident such as asphyxiation occurs due to a bad odor generated from wastewater when working in a sewer or a manhole.

Therefore, when a foreign object is trapped in a trap installed inside a sewer or a manhole, foreign matter trapped in the trap can be quickly removed from the outside without entering the inside of the sewer or manhole. It is required to research and develop a drain trap for preventing bad smell which can prevent a safety accident.
