An Improved Model to Calculate Pullback Force of Trenchless Horizontal Directional Drilling Pipeline
Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022 In the pullback operation of horizontal directional drilling pipeline crossing, the existing calculation and prediction models of pullback force are relatively simple. Each pullback force maze greatly simplifies the wellbore trajectory and fails to make a detailed analysis of the pipeline stress and external resistance when the pipeline is pulled back ...
