Horizontal directional drilling and pipe pulling technology is playing an increasingly important role in power engineering applications because of its low social and environmental impact and high construction speed. However, due to the more complex urban underground pipeline environment and the uncertainty in the process of cable pulling and laying, in order to ensure the safe laying of cables and later operation, so the cable traction force verification in the process of pulling is particularly important. Relying on specific engineering examples and relevant regulations and specifications, the cable traction force formula in the process of pulling the tube is studied, modified and given its arc-making section equivalent model, the selection principle of the discriminative cable traction method, and the influencing factors affecting the safety coefficient of cable traction force are studied.
