Long spiral pressure irrigation pedestal pile drilling tool with bottom slag removing function
The invention discloses a long spiral pressure irrigation pedestal pile drilling tool with a bottom slag cleaning function, which comprises a hole digging device, a soil cleaning device and a pedestal expanding device, the soil cleaning device is located at the upper part of the hole digging device and runs through external transmission equipment, and the pedestal expanding device is located at the bottom of the hole digging device. Spiral hole forming is achieved through the hole digging screw-in rod and the spiral blade, the grouting pile forming function is achieved through concrete pressure pouring, and under cooperation of a first gear and a second gear, the stirring sleeve and the screw-in rod can synchronously and reversely rotate, so that the pile forming effect is improved. And under the cooperation of the spiral blade and the stirring rod, rotary-cut soil and injected cement paste are mixed and stirred, so that the pile foundation is stably connected with a surrounding soil layer.
本发明公开了一种具有清底渣功能的长螺旋压灌扩底桩钻具，包括挖孔装置、清土装置和扩底装置，所述清土装置处于挖孔装置上部，通过外部传动设备运行，所述扩底装置处于挖孔装置底部。本发明通过挖孔旋进杆、螺旋叶片，实现螺旋成孔，并通过压灌混凝土，以便达到注浆成桩的功能，而在第一齿轮和第二齿轮的配合下，可以使得搅拌套以及旋进杆进行同步反向旋转，在螺旋叶片和搅拌杆的配合下将旋切下来的泥土与注入的水泥浆进行混合搅拌，从而使桩基与周围土层稳定连接。
