What is Grouting Hole Optimization in Pipe Jacking about?

This article presents experimental research on optimizing grouting holes in circular and rectangular pipe sections for trenchless pipe jacking, focusing on reducing pipe-soil frictional resistance. Key findings indicate that the layout and spacing of grouting holes significantly influence the effectiveness of slurry jackets, with optimal parameters identified as triple grouting holes, 417 mm spacing, and a 40° deflection angle. The study aims to provide valuable insights for improving construction efficienc
