Description

Technical Field

[0001] The utility model relates to the technical field of underground pipe network repair, in particular to a rotary cutting pipe repair device. Background Art

[0002] At present, the construction techniques used in the renewal and repair of underground pipelines include trenchless expansion (expansion), ramming pipe method, interlaced pipe method, and lining pipe method. When using the trenchless interlaced repair process, the length of the pipeline to be repaired is first detected by a detection device, but the instrument is not absolutely accurate. If omissions occur, construction may be required again.

However, the instrument detection may be inaccurate or have omissions, which makes it inconvenient to observe small damages and hidden dangers. The device of the utility model can have its own observation capabilities, which is convenient for personnel to further observe and prevent omissions. It is easy to observe some difficult-to-detect damages or hidden dangers and can ensure a clear monitoring angle to ensure the quality of detection. Utility Model Content
