摘要
A prestressed concrete pipe unit with a steel socket and a steel spigot includes a concrete core; a prestressed steel wire is wound around the outer wall of the concrete core; a protective layer is provided outside of the prestressed steel wire; the front end of the concrete core is provided with a spigot and the back end of the concrete core is provided with a socket so as to connect more than one pipe units end to end; a cylindrical cage of reinforcing steel bars is provided coaxially in the concrete core, and the two ends of the cylindrical cage of reinforcing steel bars connect with the spigot and the socket, respectively. More than one pipe units connect by joining the spigots with the sockets end to end, thus forming a concrete pipe.
