Wu, C.; Wen, G.; Wu, X.; Han, L.; Xu, J.; Wang, W.; Xie, H., and Li, R., 2015. Calculation method of the pull-back force for cable laying of the trenchless completed power pipeline.Typically, trenchless drilling rig is used in cable laying in power system. Then through the windlass; the cable is pulled into the pipeline. Although the size of the pull-back force is very important to calculate the pull-back force in cable laying, the existing calculation equation for pull-back force is targeted at pull-back force in pipeline laying. This article analyzes the frequently-used calculation equations and its service condition in pipeline laying. And a pull-back force test instrument in cable laying is designed, by which a large number of pull-back force of cable laying in practical engineering project is collected. Through the comparison of the measured values and calculation values by the equation for pull-back force, it is founded that the equation for pull-back force in pipeline laying is suitable for the calculation of pull-back force in cable laying in case that it multiplied by a certain coefficient.
