ABSTRACT:
A pipe joint is disclosed, along with a pipe for use with such a joint. The pipe has a double wall construction with support ribs connecting the two walls of the pipe. The pipe also includes at least one end wall having a routed groove formed therein, wherein the groove is dimensioned to receive a coupling member. A locking entrance lip is formed within the groove. The pipe joint includes two pipe sections and a coupling member that is received into the respective grooves of each pipe section and is locked into place by the locking entrance lips. The joint is fluid tight, locks the pipe sections in place, and is smooth on both the interior and exterior surfaces of the two connected pipes. In addition, the disclosed pipe joint construction is very easy to assemble, and is particularly suited for use in sewer relining operations.
