Abstract:  During tunnel shaft construction, the multiple layers of strata and thick aquifer in shaft would cause water inrush. As a result, study is conducted on components, characteristics, processing technology, grouting equipment, diffusion radius, grouting volume, and concentration of clay cement slurry. Finally, the slurry is applied to ground deep hole grouting of shaft No. 2 of Gaoligongshan tunnel, and good effect has been achieved.

Key words: Gaoligongshan tunnel, deep shaft, ground deep hole grouting, clay cement slurry, grouting parameters
