Cement soil stirring drill rod and pile machine with same
The invention discloses a cement soil stirring drill rod. The cement soil stirring drill rod comprises a hollow pile pipe, wherein a drill bit is hinged inside the hollow pile pipe through a bolt, thedrill bit is sealed with an inner cavity of the hollow pile pipe, the drill bit is a conical step, a cross groove or a cross rib is formed at the bottom of the drill bit, an exhaust pipe communicating with the inner cavity of the hollow pile pipe is welded on the side surface of the hollow pile pipe, the communication position of the exhaust pipe and the hollow pile pipe is located at the bottomof the hollow pile pipe, and the side surface of the hollow pile pipe is provided with a hopper communicating with the inner cavity of the hollow pile pipe. The invention also discloses a cement soilstirring pile machine which comprises the cement soil stirring drill rod. The cement soil stirring drill rod and the pile machine have the beneficial effect that when the cement soil stirring pile machine with the cement soil stirring drill rod is used for piling, a cement soil stirring pile which is good in quality and high in strength and can meet design requirements can be obtained.
本发明公开一种水泥土搅拌钻杆，包括空心桩管，所述空心桩管内部通过插销铰接有钻头，所述钻头与所述空心桩管内腔密封，所述钻头成圆锥形台阶，所述钻头底部形成有十字槽或者十字筋条，所述空心桩管侧面焊接有连通至空心桩管内腔的排气管，排气管与空心桩管的连通位置位于空心桩管的底部，所述空心桩管侧面设有连通至空心桩管内腔的料斗。本发明还公开一种水泥土搅拌桩机，包括所述的水泥土搅拌钻杆。本发明的有益效果在于：利用带有该水泥土搅拌钻杆的水泥土搅拌桩机进行打桩时，能够得到质量好，强度高，能够达到设计要求的水泥土搅拌桩。
