Claims

[Claims for Utility Model Registration] (1) An annular collar member whose inner circumference is approximately equal to the inner circumference of the socket is inserted into the inner circumferential surface of a portion of a cylindrical concrete pipe that forms a socket. What is claimed is: 1. A concrete pipe joint section, characterized in that the concrete pipe joint section is formed integrally with the above-mentioned collar section, and further includes an annular water-stopping member fitted into the collar section. (2) An annular collar member whose outer circumference is approximately equal to the outer circumference of the spout is inserted into the outer circumferential surface of the part forming the spout of the cylindrical concrete pipe, and is integrally molded; A concrete pipe characterized by having an annular water-stopping member fitted into the collar.
