CORRUGATED PIPE CONNECTION STRUCTURE, CAPABLE OF PREVENTING FOREIGN MATTERS FROM BEING ACCUMULATED ON THE INNER SIDE OF A COUPLER BY FORMING A STOPPING SILL ON THE OUTER SURFACE OF A CORRUGATED TUBE

摘要

PURPOSE: A corrugated pipe connection structure is provided to guarantee waterproof performance as a fastener is installed in first and second annular rim parts to additionally form a second watertight section.;CONSTITUTION: A corrugated pipe connection structure comprises first and second combining ports(120,220) and annular watertight members. The first and second combing ports are respectively formed on each end of first and second corrugated pipes. The first and second combining ports respectively comprise first and second stopping sills. The first and second stopping sills formed into annular rim shapes with diameters larger than first and second insertion portions are installed in the first and second insertion portions. The first and second stopping sills restrict the length that the first and second insertion portions are inserted into a coupler(30). The watertight members seal a gap between the inner surface of the coupler and the second insertion portion.;COPYRIGHT KIPO 2013
