PIPE REPAIRING TOOL AND PIPE REPAIRING METHOD
Document Type and Number:
Japanese Patent JP2019148297
Kind Code:
A
Abstract:
To provide a pipe repairing tool and a pipe repairing method in which a damaged part at a pipe conduit is repaired easily in a relative short time.SOLUTION: One surface 3a side of a pair of surfaces 3a and 3b having band shape and faced in opposite sides to each other is formed with both end parts 4a and 4b in a longitudinal direction in such a way that both end parts 4a and 4b of longitudinal direction are elastically displaced. A pair of side parts 5a and 5b extending in a longitudinal direction comprise a main body part 1 for maintaining a basic form F1 in which both end parts 4a and 4b are expanded against an elastic force by a warp shape toward the other surface 3b side and a repairing part 2 arranged at one surface 3a side of the main body part 1 and formed to cover a damaged portion at a pipe passage. The main body part 1 shows that the warp shape of the basic form F1 is eliminated under a state where one surface 3a is oppositely faced against the pipe passage to make a repaired form F2 where both end parts 4a and 4b are elastically displaced to cause the repairing part 2 to be pushed against the pipe passage.SELECTED DRAWING: Figure 1
