Description

A pipe lining point repair device Technical Field

[0001] The present application relates to the technical field of pipeline repair, and in particular to a pipeline lining point repair device. Background Art

[0002] With urbanization, the scale of underground drainage pipeline construction has grown exponentially. Older pipes, after long-term use, can also develop defects such as localized damage, misaligned joints, and localized corrosion. In larger cities, the drawbacks of excavation repairs are gradually becoming unacceptable to the public and government authorities; therefore, trenchless technology is gaining popularity.

[0003] Point repair technology can be used to repair local defects in pipelines. This method uses a pulling method to place an airbag with a repair material impregnated on the outer surface into the original pipeline. By inflating the airbag, the airbag expands until the repair material on the outer wall of the airbag is squeezed to fit tightly to the position to be repaired. The ultraviolet lamp installed inside the airbag is then used to cure the material, thus completing the local point repair of the pipeline lining.

[0004] However, since the airbag is generally long, the airbag generally passes through the bottom of the vertical inspection well into the horizontal pipeline to be repaired. Since the connection between the inspection well and the pipeline to be repaired is a right angle, the airbag is easily stuck at the right-angle connection when entering the pipeline to be repaired, as shown in Figure 1, resulting in the airbag being unable to enter the pipeline to be repaired.
