Hydraulic pressure test device for PCCP (prestressed concrete cylinder pipe)

The invention provides a PCCP (prestressed concrete cylinder pipe) hydraulic pressure test device which comprises a rubber O-shaped ring and a hydraulic pressure test water injection hole, the rubber O-shaped ring is mounted at an O-shaped ring mounting groove in the outer wall of a spigot steel ring, the hydraulic pressure test water injection hole is reserved in the inner wall of the spigot steel ring and is of an internal thread type, and when inner-layer concrete of a steel cylinder is machined and formed, the hydraulic pressure test water injection hole is communicated with the O-shaped ring mounting groove in the outer wall of the spigot steel ring. Due to the fact that the water pressure test water injection hole is adopted, the leakproofness of the rubber O-shaped ring can be checked during primary installation and before water passes through a pipeline, leakage points can be found and solved in time, and hidden dangers are prevented from being buried in later operation of equipment. Moreover, during
