Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pipe for a sheathed pipe construction method such as a lift-in construction method, wherein the outer diameter of the whole pipe is held down while securing sufficient strength and avoiding a collar from interrupting it. SOLUTION: The pipe 1 for the sheathed pipe construction method such as the lift-in construction method using a cage-shaped pipe transporting truck 2 for regenerating a pipe line in a non-driving manner comprises a pipe body 10, and the collar 20 mounted at one end of the pipe body 10. The pipe body 10 is formed of reinforced plastic, at one end of which a socket side small diameter portion 12 is provided having a smaller outer diameter than an intermediate portion 11. The collar 20 is formed of metal harder than the pipe body 10, whose inner peripheral face is adhered to the socket side small diameter portion 12 and whose front end extends beyond the socket side small diameter portion 12 in the axial direction.
