The Development of the Pipe Jacking Guidance Technology

Pipe jacking is one of the most important construction methods in trenchless technology. Pipe jacking guidance technology acquires the jacking route by collecting the attitude and position information of the pipe jacking machine. It ensures that the deviation between the jacking route and the route designed in the engineering drawings during the construction is kept within the error range and prevents the damage to other facilities caused by the deviation of the construction route. It improves the construction efficiency and ensures the precision and safety of pipeline laying. In this paper, the basic principle and working mode of the pipe jacking guidance system are sorted out, and the current technical means are classified and organized. A systematic overview of the research on pipe jacking guidance methods is given, the development trend of pipe jacking guidance systems towards automation, intelligence and multi-source data fusion are discussed, and the challenges faced by pipe jacking guidance systems in complex scenarios are elaborated. This is to provide guidance and reference for the research and practice in related fields and to promote the further innovation and application of pipe jacking guidance technology.
