Rotary jet grouting pile and using method thereof
The invention relates to the technical field of jet grouting piles, in particular to a jet grouting pile and a using method thereof.The jet grouting pile sequentially comprises a drill rod, an expansion arm and a drill bit from top to bottom; the drill rod comprises an outer rod and an inner rod, and the outer rod and the inner rod are detachably connected; a telescopic column is arranged at the bottom of the inner rod, the telescopic column is a circular-ring-shaped column body with a cavity formed in the middle, and the telescopic column is slidably connected with the outer rod. The upper end of the connecting rod is fixed with the bottom of the inner rod, and the lower end of the connecting rod is fixed with the drill bit; a plurality of expansion arms are uniformly arranged around the periphery of the connecting rod; the upper end of the expansion arm is hinged to the bottom of the telescopic column, and the lower end is hinged to the periphery of the lower portion of the connecting rod. The telescopic rod is arranged in the cavity, located on the periphery of the connecting rod, of the telescopic column, and the expansion arm is arranged, so that a formed pile can be thickened at the junction of soil layers when the jet grouting pile is punched and grouted, and the advantage of improving the firmness of the formed pile is achieved.
本发明涉及旋喷桩的技术领域，具体是指一种旋喷桩及其使用方法，一种旋喷桩，从上至下依次包括钻杆、扩张臂和钻头；所述钻杆包括外杆和内杆，所述外杆和内杆可拆卸连接；所述内杆底部设置有伸缩柱，所述伸缩柱为中部开设有空腔的圆环型柱体，伸缩柱与外杆滑动连接；一连接杆贯穿伸缩柱设置，其上端与内杆底部相固定，下端与钻头相固定；连接杆外围均匀环绕设置有多个扩张臂；所述扩张臂上端与所述伸缩柱底部铰接，下端与所述连接杆下部外周铰接；所述伸缩柱位于连接杆外周的空腔内设置有伸缩杆，其通过设置扩张臂，使旋喷桩在打孔和灌浆的时候可以在土层交界处对成桩进行加粗，已达到提升成桩牢固性的优点。
