A multi-functional small manhole is provided to use various-sized connecting pipes connected to height-regulating pipes to one small manhole variously, to filter out impurities and to cut off an offensive odor regardless of the quantity of flow and the speed of a current using an offensive odor prevention member and to connect pipes connected to an inlet and an outlet easily. The multi-functional small manhole comprises a connection member(300) installed between a manhole main body(100) and a height-regulating pipe(200) and provided with a connecting groove(310) fitted to the manhole main body and a support pipe(320) coupled to the height-regulating pipe, an odor prevention member(400) composed of a holder member(410) provided with a coupling groove(412) formed on a body(411) inserted to an opening of the small manhole and a projection(414) formed on the upper part of a connecting fitting unit(413) fitted with a pipe where waste water flows in and out to be fitted to a coupling hole(110) formed on the manhole main body, a conversion connection member(420) integrated with a connection unit(421) provided with a projection(423) fitted to the connecting fitting unit of the holder member and inserted to the coupling groove on a conversion unit(422) changing the flow direction of waste water and a basket member(430) provided with a coupling groove(431) fitted with the projection of the conversion unit, a space(432) storing dropped waste water and an end projection(433) preventing the separation of the conversion connection member from the connecting fitting unit of the holder member, and an eccentric bushing(500) provided with a projection(512) formed on the outside of a body(510), a connecting hole(513) fitted with the pipe and an incline formed on the end of the connecting hole. |
