New Wall Protection and Drag Reduction Technologies for Long Distance Large Diameter Pipe Jacking in Complex Strata
Long-distance (single segment greater than 1000 m) large-diameter (inner diameter greater than 3.5 m, outer diameter greater than 4 m) pipe jacking in complex strata presents numerous challenges, including poor stability, susceptibility to collapse, wall protection difficulties and high jacking resistance. This paper focuses on addressing these issues by conducting systematic research on wall protection and drag reduction technology. Firstly, we thoroughly investigate into the mechanism of wall protection for large diameter pipes and drag reduction for long distance pipe jacking. We identify optimal configuration processes and grouting technologies for wall protection and drag reduction slurry. Secondly, we introduce two new slurry systems specifically for wall protection and drag reduction, highlighting their unique characteristics. Lastly, we develop an evaluation method to assess the effectiveness of wall protection and drag reduction. The results of this research have been validated by several large-scale pipe jacking projects in Yunnan, Inner Mongolia, Jiangsu and Hubei, China. These projects have demonstrated significant improvements with the implementation of our research findings. |
