ABSTRACT:
An apparatus for forming underground pipelines of the type which includes a plurality of component sections at least partially enclosed by a formable outer component, such apparatus comprising a receptacle, including a bulkhead at one end of the receptacle. The receptacle has an inlet opening sized to receive the inner component sections and the bulkhead has an outlet opening of sufficient size to permit an inner component section to pass rearwardly from the receptacle through the outlet opening. The apparatus and the inner component section are relatively axially advanceable so that the inner component section can be moved rearwardly relative to the apparatus and through the outlet opening. The formable outer component is delivered from a source of the outer component to a location rearwardly of the bulkhead. The bulkhead inhibits the flow of formable outer component forwardly through the outlet opening. The source of the formable outer component may be remote from the apparatus.
