| Abstract: | High pressure jet grouting technology is an important method for stratum strengthening.In the left lane exit of Guanyinling tunnel in Yongzhou to Lanshan highway, flowing mud and sand stratum appeared at the tunnel heading due to surface subsidence. High pressure jet grouting technology effectively strengthened mud and sand stratum, and ensured stability of the tunnel stratum and smooth construction of the project. The design method and construction technology of high pressure jet grouting pile are described based on the actual situation of the project. |
