There are two main types of construction for urban drainage networks, which are open laying construction and trenchless construction. The trenchless construction mainly includes the horizontal directional drilling technology, pipe jacking technology and pulling pipe-jacking technology. The calculation of jacking resistance in existing specifications does not take into account the frictional resistance generated by the self-weight of the pipeline, and the calculation of oncoming earth pressure mostly relies on experience. Combined with the practice of Chaozhou City FEngjiang Deep Pit Guokao Section Up-to-standard Project (Chaozhou Section) Phase I Project, the construction steps and characteristics of the pulling pipe-jacking technology are introduced, the calculation formula of jacking resistance given in the specification is optimized so as to obtain the minimum jacking force and head pulling force required for the equipment, which provides the basis for the reasonable selection of pulling pipe-jacking equipment. The different pipe laying methods are compared to provide the reference for the construction of similar projects.
