Claim 6:
7. The method of claim 6, wherein the pipe is a prestressed concrete cylinder pipe (PCCP) having a concrete outer layer, an interior metal cylinder, and wire 1 wound around the metal cylinder, further comprising the steps of: placing a left side restraining clamp onto a left side of the pipe and a right side restraining clamp onto a right side of the pipe, thereby restraining pre-stressed tension wire on a right side and a left side of the pipe;
placing a center restraining clamp on the pipe between the left side restraining clamp and the right side restraining clamp, thereby restraining pre-stressed tension wire in a center portion of the PCCP pipe, wherein the center restraining clamp comprises an upper mounting flange on an upper portion of the clamp;
removing the concrete layer and the tension wire in the left medial portion of the pipe and in the right medial portion of the pipe, thereby exposing the interior metal cylinder in the left medial portion and the right medial portion;
placing the housing around the center restraining clamp so that a left side opening of the housing surrounds the interior metal cylinder in a left medial portion of the pipe to the left of the center restraining clamp and a right side opening that surrounds the interior metal cylinder in a right medial portion of the pipe to the right of the center restraining clamp, wherein the housing is placed in fluid-tight engagement with the pipe.
