Abstract
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.
Claims19
A corrugated pipe connection joint structure for joining two sections of corrugated pipe comprising:
- opposing bell-formed ends,
- a connector insert defining opposing ends and a push-ring;
- at least one gasket positioned on at least one of said opposing ends of said connector insert;
- wherein said opposing ends of said connector insert are positioned in said bell-formed ends, with said corresponding at least one gasket forming a seal therebetween.
A corrugated pipe connector insert comprising:
- a pair of opposing ends;
- at least one gasket positioned on at least one of said opposing ends having an outer diameter greater than said outer diameter of said opposing ends;
- and
- a push-ring disposed between said opposing ends having an outer diameter substantially equal to an outer diameter of said bell formed ends.
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.
