Abstract
A prestressed concrete pressure pipe, characterized by a molded concrete pipe core with a dowel having an annular surface for coupling joint sealing means, a tensioned wire wrap subjecting the core to circumferential compression, said wrap-having one end anchored near said joint sealing surface, said core containing a plurality of prestressed wires spaced circumferentially from said core and extending substantially along the length of the core, a prestressed loop contained in the concrete of said core, said loop substantially concentric to the axis of said core and located axially inward from the end face of the core at the spike end of the core, said prestressed wires engaging the interior of said loop and having portions offset radially outwardly from their points of engagement with said loop and toward said face from end to end d e spike of the nucleus.
