Claims

[Scope of utility model registration request]

A backing insertion ring, which has an inner diameter slightly larger than the outer diameter of the main pipe and whose outer surface is coated with mortar and outer pipe, is provided on the outer peripheral surface of the main pipe of one of the steel pipes to be connected. Mortar on the outer circumferential surface and the outer pipe are removed, and an outer joint ring has a socket, a reduced part having an outer diameter slightly smaller than the inner diameter of the outer pipe, and an enlarged part slightly larger than the outer diameter of the outer pipe. A steel pipe joint for propulsion, characterized in that the gap between the outer joint ring and the outer surface of the main pipe is filled with a fast-hardening material.
