[0028] Working principle: In use, first, insert the connecting ring 4 into the connecting groove 3 at one end of one of the pipe bodies 1, and then insert the connecting ring 4 into the connecting groove 3 at one end of the other pipe body 1, so that the connecting ring 4 is installed between the two connecting grooves 3. At this time, the two connecting pipes 2 will be connected. Then, use two arc-shaped sealing plates 7 to fix and seal the connection between the two connecting pipes 2, so that the arc-shaped sealing plates 7 and the sealing gaskets 11 are staggered for better sealing effect. Use fixing bolts 10 to pass through the two corresponding connecting holes 9 on the two connecting ears 8 to connect and fix the two arc-shaped sealing plates 7, thus completing the connection and installation of the pipe bodies 1 and completing the splicing of the drainage pipe. When it is necessary to maintain and clean the inside of the pipe body 1, the fixing bolts 10 can be rotated to release the fixation between the two arc-shaped sealing plates 7, and then the arc-shaped sealing plates 7 can be removed. The exposed cleaning holes 5 can be used to maintain and clean the pipe body 1.
