ABSTRACT:
An end cap particularly adapted for capping an arch conduit is provided. The end cap is comprised of an arch body including opposed arcuate side walls integrally joined together at an apex area. Opposed arcuate end walls are integrally joined at the terminal ends of the side walls and the apex area. A plurality of protruding ribs are disposed circumferentially of the end cap and are interrupted at the apex area to provide a relatively smooth, non-ribbed area. The ribs taper towards the apex area and towards rounded base areas of the side walls.
A method is disclosed for capping a continuous arch conduit line comprising halting the subterranean installation of the conduit line at a place generally designated for capping; providing an opening in a wall portion of the line for insertion of the end cap; inserting the end cap in the line through the opening in mating cross-sectional alignment with the line; continuing installation of the line at least until the end cap is installed below ground; and, severing the line to form a terminal end.
