<P>PROBLEM TO BE SOLVED: To provide a novel method of regenerating an existing pipe capable of uniformly impregnating a resin impregnation layer with a base material resin, and capable of expecting the smoothness of the inverting work of a lining material. <P>SOLUTION: The inner wall of the existing pipe is coated with the lining material 1 by impregnating the resin impregnation layer 12 in the tubular lining material 1, inserting the lining material 1 impregnated with the curing resin into the existing pipe and expanding and solidifying. As the base material resin, an epoxy based mixture having viscosity which is lowered to develop fluidity to have in a viscosity range of 200-5,000 mPa s at condition of a temperature ≤10°C in an uncured state is used and the resin impregnation layer 12 is impregnated with the base material resin having viscosity adjusted to 200-5,000 mPa s by cooling the base material resin in the uncured state to ≤10°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
