Using method for U-shaped-pile pile forming device
The invention discloses a using method for a U-shaped-pile pile forming device. Synchronous and opposite left-and-right movement is formed by a left half U-shaped frame and a right half U-shaped frame, and first tooth tips and second tooth tips on the left half U-shaped frame cut a soil layer outside a drill bit at the lower end of a first drill rod, a drill bit at the lower end of a second drill rod and a drill bit at the lower end of a fifth drill rod and inside the left half U-shaped frame in the motion of the left half U-shaped frame so that the soil layer and water can be stirred to form slurry, and first tooth tips and second tooth tips on the right half U-shaped frame cut a soil layer outside a drill bit at the lower end of a third drill rod, a drill bit at the lower end of a fourth drill rod and a drill bit at the lower end of a sixth drill rod and inside the right half U-shaped frame in the motion of the right half U-shaped frame so that the soil layer and water can be stirred to form slurry; the slurry flows out of a hole; and in the downward pushing process, a first main drilling rod and a second main drilling rod form a U-shaped hole body.
