Abstract:
The geological conditions of Railway Station station of No. 1 Line of Nanning Metro are complex, the cobble/gravel strata is waterrich and highlypermeable, and the underground water level is about 6 m below the ground surface. The strata is consolidated by means of Soletanche grouting, so as to guarantee the safety of the buildings around the diaphragm wall. In the paper, comparison and contrast is made among the effect of singlecomponent grout, that of twocomponent grout and that of composite grout. Composite grout is adopted for the Soletanche grouting and good grouting effect has been achieved. The maximum accumulated settlement of the buildings is less than 3 mm during the construction of the diaphragm wall, and the safety of the buildings is guaranteed.
Key words: rich water with high pressure, cobble/gravel strata, building protection, Soletanche grouting, settlement control
