It is the backbone of urban water pollution prevention and control, urban drainage and flood control, and an important indicator of the level of modern cities. At present, the repair of underground pipelines in most cities in my country adopts the method of re-burying pipes after excavation. With the progress of urbanization, urban underground pipelines are complicated and the load of urban roads is becoming more and more serious, which makes underground pipelines have a lot of technical problems in the repair process. With the continuous improvement of urban construction, trenchless pipe laying, pipe repair and pipe replacement technology has been increasingly favored by underground pipeline industry management departments for its advantages such as no impact on subsequent traffic, fast pipe laying speed, high efficiency, no environmental damage, and no impact on people's normal work and life.

[0003] Trenchless pipeline repair technology first emerged in the oil and gas industry, mainly used for the renewal and repair of oil and gas pipelines, and then gradually applied to the renovation and reconstruction of water supply and drainage pipelines.
