末充頭管。At one end of the uniform outer diameter tube, there are female threaded holes penetrating in the radial direction at multiple positions in the circumferential direction, and at the other end of the uniform outer diameter tube than the female threaded holes, the outer diameter of the uniform outer diameter tube is an annular member having an outer circumferential surface formed with a large diameter; A flange-like member having an outer diameter larger than the outer circumferential surface is installed, and an annular sealing material backed up by the flange-like member is interposed between the outer circumferential surface and the inner circumferential surface of the existing pipe. 1. A pressing member for pressing the sealing material by a bolt screwed into the other end surface of the annular member is provided so as to be separated in the circumferential direction avoiding the female threaded hole. A tube-filled head tube for a pipe-in-pipe method, characterized in that a centering fixing bolt is provided whose tip end screws out from the female threaded hole and comes into contact with the inner circumferential surface of the existing tube.
