Description

Technical Field

[0001] The utility model relates to the technical field of trenchless pipeline replacement, in particular to a modular traction device for trenchless pipeline replacement. Background Art

[0002] With the development of urbanization, the construction of drainage pipes increases every year, and the number of urban underground pipe networks continues to increase. However, after years of operation, the underground pipes have been corroded, leaked seriously, damaged and deformed, and unevenly settled due to insufficient investment in maintenance and repair. Once such pipes are disturbed by external factors, they are more likely to cause accidents such as road collapse and drainage pipe bursts, resulting in serious economic losses and safety hazards. However, replacing new pipes along the entire line not only requires a huge amount of work, but also requires a large amount of money and a long project period. Therefore, in order to save costs, pipe repair technology is often used to extend the service life of the pipes. Pipe repair technology can be divided into excavation repair technology and trenchless repair technology according to construction conditions. Trenchless repair technology is widely used because of its small impact on infrastructure, low maintenance cost, high construction and repair efficiency, and good repair effect. During the pipe repair process, the fiberglass hose needs to be pulled into the pipe to be repaired.
