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.
