Analysis of Grouting Impact on Soil Displacement in Pipe Jacking Construction
The slurry balance jacking process often generates surface uplift or cavity around thr tube because of an irrational exchanging slurry rate. Grout reinforcement can prevent and control the cavity effectively and prevent building subsidence above the pipeline during the construction process. Combined with the Xi'an sewage pipe jacking project, for instance, the numerical simulation method and engineering analogy method have been used to analyze the soil layers' displacement during grouting reinforcing cavities. Results suggest that while using 0.28~0.3MPa grouting pressure to reinforce cavities around tubes, uplift values of ground surface and displacement values of tubes can meet requirements.
