PURPOSE: A collecting well structure with connection units of various diameters for a sewage pipe is provided to improve convenience by freely drilling sewage pipes depending on the diameter of the sewage pipe. CONSTITUTION: A collecting well structure with connection units of various diameters for a sewage pipe comprises a collecting well body(11), multiple pipe control units(13), multiple height adjustment frames(16), and a rubber ring(18). The pipe control units are formed on the surface of walls(12) so that sewer pipes of various diameters can be connected and fixed to the collecting well body. End projections are displayed on the pipe control units depending on the diameters of sewage pipes. The height adjustment frames are placed on the top of the collecting well body and adjusts the height. The rubber ring is inserted into a fixing groove(17) formed between the collecting well body and the height adjustment frames and prevents a water leak. |
