PIPE CONSTITUENT MEMBER FOR LINING EXISTING PIPE, AND EXISTING PIPE LINING METHOD USING THE MEMBER

PROBLEM TO BE SOLVED: To curtail a construction period and to improve quality by simplifying the shape of a pipe constituent member, obviating a joiner, facilitating the joining between spirally wound pipe constituent members, securing strength and water tightness sufficiently by simple structure, obviating a spacer for packing grout, support for preventing the bend of a pipe, water change, and others, reducing members, and preventing a grout packing process from being complex. SOLUTION: Ribs 6b are erected on both sides in the length direction of a main body part, a belt-shaped body 6 in which a recessed part is formed between the ribs 6b and a cylindrical body 7 which is housed in the recessed part and installed in the clearance between it and an existing pipe are combined, the belt-shaped bodies 6 form a joining strip 8a for forming a spiral pipe body by joining the bodies 6 to each other on the outsides of ribs of the right and left side fringes and a groove strip 8b. The cylindrical body 7 is formed from a material which allows the water of a filler packed in the inside to pass but does not allow solids to pass and is swelled by internal pressurization.
