PROBLEM TO BE SOLVED: To provide a branch pipe lining material capable of certainly bonding and integrating the flange part of the brach pipe lining material and a main pipe lining material and a pipe lining method. SOLUTION: In a branch pipe lining material 1 constituted by impregnating a tubular resin absorbing material 4 having a cured flange part 5 formed to one end thereof with an uncured curable resin, a plurality of circular holes 6, 7, 8 are bored in the flange part 5 of the tubular resin absorbing material 4 and a string like resin absorbing material 9 is passed through at least a part of the circular holes 6, 8 to connect the circular holes 6, 8 mutually. Since the uncured curable resin bled from the main pipe lining material is infiltrated into the string like resin absorbing material 9 to be cured, the flange part of the branch pipe lining material 1 and the main pipe lining material are more strongly bonded and integrated. |
