Circular gravel layer triaxial mixer drill bit and construction method
The invention relates to a circular gravel layer triaxial mixer drill bit and a construction method. The drill bit comprises a drill rod; a grouting steel pipe is arranged in the drill rod; an interpolating joint is arranged at the tail part of the drill rod; a forward head is arranged at the head part of the drill rod; a drill bit row is arranged at the position, behind the forward head, of the drill rod; a drill bit neck protecting wing plate is arranged at the position, behind the drill bit row, of the drill rod; and alloy drill teeth are arranged on the drill bit row. The method comprisesthe steps: (1) measuring and lofting; (2) excavating a groove; (3) correctly positioning a triaxial mixer at a pile position after the triaxial mixer is assembled; (4) mixing cement slurry, starting an air compressor, and sending the cement slurry to a pile machine; (5) spraying the slurry from the triaxial mixer drill bit, performing stirring, positioning and sinking of A, and performing stirringand sinking of B to a designed pile bottom elevation while spraying the slurry; (6) spraying the slurry from the triaxial mixer drill bit, and performing stirring and lifting of C to the designed pile top elevation; (7) after the construction is finished, starting construction D of a next group of piles; and (8) after the construction is finished completely, performing residual soil treatment andwithdrawing the mixer.
本发明涉及一种圆砾层三轴搅拌机钻头及施工方法，该钻头包括内置有注浆钢管的钻杆，所述钻杆的尾部设有内插式接头，所所述钻杆的头部设有前进头，前进头后方的钻杆上设有钻头排，钻头排后方的钻杆上设有钻头护颈翼板，钻头排上布设有合金钻牙。该方法的步骤为：1)测量放样，2)开挖沟槽，3)三轴搅拌机组装后在桩位正确就位，4)拌制水泥浆液，开启空压机，送水泥浆液至桩机，5)三轴搅拌机钻头喷浆、搅拌定位下沉A并边喷桨边搅拌下沉B至设计桩底标高，6)三轴搅拌机钻头喷浆、搅拌提升C至设计桩顶标高，7)施工完毕后，进入下组桩施工D，8)施工全部完毕后进行残土处理和搅拌机械撤出。
