摘要： PROBLEM TO BE SOLVED: To enable connection of profiles in each of which a metallic reinforcing material is buried, in a state wherein the respective reinforcing materials of the profiles are joined together firmly. SOLUTION: Profiles 10 of which side edge parts on one side are put in a state of engagement on the occasion when the profiles are so wound helically as to be along the inner peripheral surfaces of existing pipes have strip-plate-like base main body parts 11 made of synthetic resin and having flexibility, respectively. The base main body part 11 is provided with a reinforcing part 18 so that a hollow part 10a having a triangular section and being continuous in the longitudinal direction is formed, and a metallic reinforcing material 19 is buried in the reinforcing part 18 continuously in the longitudinal direction. In the case when the profiles 10 in a pair are connected, the end faces of the base main body parts 11 are fused to each other in a state wherein side parts of a metal joint 20 are inserted into the respective hollow parts 10a of the profiles. The reinforcing part 18 is shaven off thereafter so that the reinforcing material 19 be exposed, and the side parts of the reinforcing materials 19 and the metal joints 20 are spot-welded to each other respectively.

CONSTITUTION: An invert is removed from the bottom of a manhole 10, a spiral pipe fixing device 30 is set on a flat bottom surface 13, and a pipe producing machine 40 is set on the opening of the manhole 10. Also a spiral pipe 15 is produced by the pipe producing machine 40, and the produced spiral pipe 15 is inserted directly into the manhole 10. Then the bottom part of the spiral. pipe 15 is set movably in radial direction without moving in circumferential direction by the fixing member 33 of the spiral pipe fixing device 30, and a profile 20 is fed by the pipe producing machine 40. Thus the bottom part of the spiral pipe 15 is increased in diameter so that it is adhered closely to the internal surfaces of the bottom part of the manhole 10. Thereafter the spiral pipe 15 is increased in diameter from the bottom side upward in order, and fitted closely to the entire inner surfaces of the manhole 10.

摘要： PURPOSE:To provide a mounting pipe to provide a reliable cutoff state through simple execution of a work and a method for joining a mounting pipe with a buried main pipe by using the mounting pipe. CONSTITUTION:In a method for joining a mounting pipe 1 with a buried main pipe 2, the mounting pipe 1 is intended to be joined with the outer peripheral surface of the buried main pipe 2. The opposite arcuate part 11 of the tip of the mounting pipe 1 is protruded approximately in the shape of a bow in the axial direction of a pipe and a groove part 12 in the shape of a chevron as seen from a side crossing the axial direction of the pipe at right angles is formed. In a state that the outer perpheral surface of the buried main pipe 2 is brought into contact with a space between the groove parts 12 and the mounting pipe 1 effects allowable maximum displacement from the buried main pipe 2, the arcuate part 11 is brought into contact along with the outer peripheral surface of the buried main pipe 2. Further, in a state that the tip part of the mounting pipe 1 is brought into contact with the outer peripheral surface of the buried main pipe 2, the tip part of the mounting pipe 1 is joined with a joining hole 21 drilled in the buried main pipe 2 by mounting a resin mat 4 from the inner side of the buried main pipe 2.
