Corrugated pipe connection joint
View Patent ↗A corrugated pipe connection joint structure and method for connecting two sections of corrugated pipe. The joint structure includes opposing bell-formed ends with reduced corrugations, a connector insert including a gasket on either end and a push-ring. The gasket(s) form a seal sufficient to keep fluid inside the pipe, and to help keep the joint structure from separating under normal use.
1. A method for joining two corrugated pipe sections comprising the steps of:
bell-forming at least one end of a first corrugated pipe section and at least one end of a second corrugated pipe section;
reducing an amount of corrugations at said bell-formed ends of said first and second corrugated pipe sections;
inserting a connector insert having a first end and a second end adapted to fit within said first and second bell-formed ends of said corrugated pipe sections into said first bell-formed end of said corrugated pipe section; and
inserting said second bell-formed corrugated pipe section over said second end of said connector insert.
2. The method for joining two corrugated pipe sections of claim 1 , wherein said reducing step further comprises reducing said corrugations in height.
3. The method for joining two corrugated pipe sections of claim 1 , wherein said bell-forming step further comprises heating said at least one end of said first and said second ends of corrugated pipe section and molding said first and second ends of corrugated pipe section.
