The results of the engineering practice showed that, in the geological conditions suitable for boring with traditional percussion drills, boring with percussion drills in conjunction with post grouting technique can effectively solve the problem of the large amount of dreg deposited at the bottom of the bore, thus reducing the settlement and improving the bearing capacity of the foundation piles
工程結果表明，在適宜選用傳統沖擊鉆機成孔的地質條件下，採用后壓漿技術與沖擊鉆機成孔相結合的施工方法能有效地解決孔底沉渣量過大的難題，減少沉降量，提高基樁承載力。
