Abstract：
Guquan Conference Center Project is located on an irregular mountainside and the whole architectural structure rises along the uneven terrain, so many permanent anchor bars are set to ensure the mountain stability. The stratum belongs to intensely weathered rock and can not withstand the external water rush which may affect the stratum stability. High-power air compressor "air-driven" dry-working drilling hole-forming by wet-working casing anchor rod drill is adopted to successfully solve the difficulties in anchor rod construction in mountainous rock stratum and to ensure the construction quality.
