Drilling tool for pressure irrigation cement soil static pressure pipe pile and construction method
The invention discloses a drilling tool for a pressure irrigation cement soil static pressure pipe pile and a construction method, and belongs to the technical field of capital construction foundationconstruction mechanical equipment and construction methods. According to the technical scheme, a drill bit is arranged at the front end of a drill bit sleeve; flange plates are welded to the rear endof the drill bit sleeve; a spiral blade is welded to the lower portion of the outer wall of the drill bit sleeve; a stirring blade is welded to the upper portion of the outer wall of the drill bit sleeve; flange plates are welded to the two ends of a stirring sleeve correspondingly; a stirring blade is welded to the outer wall of the stirring sleeve; flange plates are welded to the two ends of aspiral sleeve correspondingly; a spiral blade is welded to the outer wall of the spiral sleeve; the drill bit sleeve, the stirring sleeve and the spiral sleeve are connected through the flange platesby bolts; and the flange plate at the upper end of the spiral sleeve is connected with a drilling machine. According to the drilling tool, hole forming and stirring integration can be achieved, hole collapse and drilling hole blockage are effectively prevented, the stirring time is saved, construction is facilitated, the construction period is shortened, and the cost is reduced. The construction efficiency and quality are improved, and a new development way is opened up for pressure irrigation cement soil static pressure pipe pile construction.
一种用于压灌水泥土静压管桩的钻具及施工方法，属于基建地基施工机械设备及施工方法技术领域。其技术方案是：钻头套筒的前端为钻头，钻头套筒的后端焊接法兰盘，钻头套筒外壁的下部焊接有螺旋叶片，钻头套筒外壁的上部焊接有搅拌叶片，搅拌套筒的两端分别焊接法兰盘，搅拌套筒外壁上焊接搅拌叶片，螺旋套筒的两端分别焊接法兰盘，螺旋套筒外壁上焊接螺旋叶片，钻头套筒、搅拌套筒和螺旋套筒分别通过法兰盘由螺栓相连接，螺旋套筒上端的法兰盘与钻机相连接。本发明能够实现成孔搅拌一体化，有效防止塌孔和堵塞钻孔，节省了搅拌时间，还方便了施工、节约了工期、降低了成本。提高了施工效率和质量，为圧灌水泥土静压管桩施工开辟新的发展途径。
