PURPOSE: A multi-purpose connector of an airtight manhole is provided to maintain smooth flow of waste water by allowing a waste water pipe to be coupled to the pipe insertion hole of small diameter. CONSTITUTION: A multi-purpose connector of an airtight manhole includes a connector body(110) in which an inlet/outlet port insertion hole(111) and a pipe insertion hole(112) are formed opposite to each other. A waste water inlet(210) or a waste water outlet(220) is coupled to the inlet/outlet insertion hole. A waste water pipe(300) is inserted into the pipe insertion hole having a smaller diameter than the inlet/outlet insertion hole. The bottom of the insertion holes are flat surface. |
