High-durability prestressed concrete pipe and preparation method thereof

The invention provides a high-durability prestressed concrete pipe and a preparation method thereof, and relates to the technical field of prestressed concrete cylinder pipes. The high-durability prestressed concrete pipe comprises a pipe core. The pipe core comprises a steel cylinder body, and the inner surface and the outer surface of the steel cylinder body are each provided with a first concrete layer. The first concrete layer is formed by pouring C60 high-performance concrete; a prestressed steel wire is wound on the outer side of the pipe core; the prestressed steel wire is a spiral rib high-strength steel wire; a second concrete layer is arranged on the outer side of the prestressed steel wire; and the second concrete layer is formed by pouring C70 high-performance concrete. The bonding strength with the outermost protective layer concrete can be greatly improved through the spiral rib steel wires, and the hollowing problem of the pipe core and the protective layer is solved; the second concrete layer
