The utility model discloses an identification PCCP (prestressed concrete cylinder pipe), which relates to the technical field of concrete prefabricated parts and comprises a PCCP frame and an integrally formed concrete chip arranged on the PCCP frame. The PCCP frame comprises a peripheral steel cylinder, a pipe core outer wall concrete layer wrapping the peripheral steel cylinder, a prestressed steel wire wound around the periphery of the pipe core outer wall concrete layer, a mortar protection layer wrapping the prestressed steel wire and a pipe core inner wall concrete layer arranged on the inner side of the peripheral steel cylinder. The integrally-formed concrete chip is arranged on a peripheral steel cylinder at the socket end of the PCCP pipe frame and / or a concrete layer on the inner wall of the pipe core; the integrally-formed concrete chip is arranged in the identification PCCP pipe, so that identification and traceability management are facilitated. The PCCP information recording device is simple in principle and obvious in effect, can be effectively suitable for PCCPs with different information recording requirements, marks and traces the PCCPs at the same time, and remarkably improves the quality management level of concrete products or structures.
