A belt for repairing a pipe is provided to precluded an additional support during construction and allow watertight attachment by applying small pressure on belts. At least one supportive trim(120) is formed along longitudinal direction which a spiral advances. A space is formed between a pipe inner circumference and a body, and a filler such as mortar is filled inside the space. The supportive trim forms an insertion part(121) in the upper end in order to be assembled to the existing pipe inner circumference. When the insertion hole is cut on the inner circumference of the pipe, the insertion part is inserted into the insertion hole.
