SYSTEM AND METHOD FOR PIPELINE RENOVATION
The present invention relates to a pipe repair apparatus and a pipe repair method using the same, which can pull a repair tube in a pipe very rapidly and stably, and also can assure sealing performance as to an open end of the repair tube. The pipe repair apparatus according to the present invention includes: the repair tube which is longitudinally installed in a predetermined length in an underground pipe; a sealing unit which has at least a pair of pressurizing objects sealing the end of the repair tube by pressurizing the end upward and downward; and an injection tube which injects an expansion fluid into the repair tube by being inserted into one end of the repair tube. The pair of pressurizing objects are combined with each other vertically under the state that the end part of the repair tube is intervened between the pair of pressurizing objects, thereby sealing the end part of the repair tube. An end part of a pulling wire is connected to the sealing unit and thus the sealing unit and the repair tube are pulled from the underground pipe by pulling of the pulling wire.
