The Pingding section of G22 Qinglan Expressway,the Baotian(Tianshui Transit)section of G30 Lianhuo Expressway,and the Fengchang section of G70 Fuyin Expressway have been in operation for many years,and some sections have experienced serious roadbed settlement diseases.After investigation and re-search,high-pressure rotary jet grouting piles were finally used to reinforce severely settled road sections.Af-ter completing the reinforcement treatment for a period of time,the settlement of the roadbed was tested a-gain,and the settlement value met the requirements,proving that high-pressure rotary jet grouting piles have a significant effect on roadbed settlement treatment.
