<p><P>PROBLEM TO BE SOLVED: To provide a method for regenerating a vertical drain pipe which can cure the thermosetting resin of a liner material uniformly even when the drain pipe is long and an apparatus for the method. <P>SOLUTION: In the apparatus for regenerating the degraded vertical drain pipe (Pv) in which a laminated tube with a tube 1 of a flexible synthetic resin film laminated on a tube 1 of a fibrous material impregnated with the thermosetting resin is used as the liner material 3 for lining the drain pipe (Pv), the connection metal piece 5 of the upper part of the drain pipe (Pv) into which the reversed liner material 3 is inserted is installed, a means 43 which allows the passage of liquid but does not allow the passage of gas is installed in the lower part of the drain pipe (Pv), and while the liner material 3 is contacted with the inner surface of the drain pipe (Pv) by the air pressure of the inside, a warm water boiler 6 heating warm water which passed through the means 43 by dropping the warm water from the connection metal piece 5 and a pump 8 sending the warm water heated by the boiler 6 to the connection metal piece 5 are provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
