Technical Field

[0001] The utility model relates to a pipeline inner wall repairing device, belonging to the technical field of municipal engineering maintenance. Background Art

[0002] Currently, pipeline inner wall repair technology is widely used in many types of underground pipelines to repair aging or damaged pipelines. This type of repair material does not adhere well to the inner wall of the pipeline, which can easily lead to peeling or loose adhesion of the repair material, thus affecting the quality and durability of the repair. In addition, when many devices are operated in complex pipeline environments, due to the large size and complex structure of the equipment, it is difficult to achieve stable positioning and uniform application of repair materials, which increases the construction difficulty and time cost.

[0003] Due to the length of the pipeline itself and the current working conditions, some equipment is difficult to accurately control and adjust, which can easily lead to waste of repair materials or uneven coverage, further affecting the repair effect and the adaptability of the equipment.
