<P>PROBLEM TO BE SOLVED: To provide a man-hole regenerative method for a regenerative pipe capable of preventing the development of a crack with elapse of time after the construction work by simple regeneration work at a low cost. <P>SOLUTION: A cylindrical lining pipe section Ra is previously formed in a cylindrical dummy pipe so that a profile consisting of a stripe-shaped member is spirally wound to become a cylindrical-shape slightly smaller than the inside diameter of a man-hole M, and after a sectional shape of the cylindrical lining pipe section is contracted in the shape of a pleat by a deformation device, the cylindrical lining pipe section is inserted into the man-hole, and then, after the cylindrical lining pipe section is heated to expansively advance it by supplying vapor between the cylindrical lining pipe section and an approximately cylindrical part Mb, compressed air is injected into a packer to recover the shape of the cylindrical lining pipe section after the packer is inserted into the cylindrical lining pipe section in a state to contract the packer, and after that, mortar MT is injected between the cylindrical lining pipe section and the approximately cylindrical part, and the cylindrical lining pipe section is adhered to the approximately cylindrical part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
