针对旋挖钻机能自动定位，垂直度自动检测，自动化程度高，钻头可快速穿过各种复杂地层的特征，提出了在杂填土、回填土较深的地质条件下用旋挖桩来代替人工挖孔桩的桩基施工技术，通过实际桩基工程施工案例显示旋挖桩比人工挖孔桩在成本、工期等方面有着很大的优势。
針對鏇挖鑽機能自動定位，垂直度自動檢測，自動化程度高，鑽頭可快速穿過各種複雜地層的特徵，提齣瞭在雜填土、迴填土較深的地質條件下用鏇挖樁來代替人工挖孔樁的樁基施工技術，通過實際樁基工程施工案例顯示鏇挖樁比人工挖孔樁在成本、工期等方麵有著很大的優勢。

According to the characteristics of rotary drilling rig could automatic positioning,perpendicularity automatic detection,high automation degree,the drill bit could quickly through various stratums,this paper proposed the pile foundation construction technology using rotary drilling pile instead of manual hole digging pile under miscellaneous fill,backfill deep geological condition,through the pile foundation engineering construction cases showed the rotary drilling pile had very big superiority than manual hole digging pile in cost,construction period and other aspects.
