A repairing apparatus being adaptable to pipes of various inner diameter and length

摘要

The present invention relates to a repair apparatus capable of repairing pipes having various diameters and lengths capable of performing partial repairs by using and applying one repair apparatus to the pipes having various diameters. The repair apparatus of the present invention comprises: a pair of metal bodies having a punching hole formed therein, arranged to be spaced apart from each other at regular intervals, and having a cylindrical shape; an air tube disposed between the metal bodies, coupled by a fastening means, having an air insertion space unit formed therein, having a folding unit formed on both sides thereof, and having an air supply hole formed on a surface which comes in contact with the metal bodies to be expanded by the diameter of pipes when air is filled in the air insertion space unit; an air supply line connected to the air supply hole; and a retraction line coupled to the metal bodies. According to the present invention, the diameter of the repair apparatus increases to be applied to pipes having various diameters; thereby improving workers convenience and work efficiency. In addition, a middle portion and both ends of an air tube are expanded to a same diameter to each other to improve a performance of attachment of a repair material. Moreover, the length of the repair apparatus is able to be reduced, and the air tube is able to easily be replaced when the air tube is damaged as the air tube formed in the repair apparatus is easily attached and detached.
