Soil improvement using jet grouting enhances mechanical properties in preparation for metro line tunneling.
At the BW Plot 11C site, the improvement of soil mechanical properties was carried out using the jet grouting method. The specificity of the project lies in the fact that beneath a portion of the structure a planned route of the future metro line is located, whose construction technology imposes strict requirements regarding the foundation design. For this reason, after analyzing possible alternatives, the jet grouting method was selected for soil improvement. This solution ensured the required bearing capacity and deformability parameters of the soil, while simultaneously preserving the conditions necessary for the unobstructed execution of future tunneling works.
