Abstract

Provided is a drill jig. A third motor drives a stirring drill bit at the lower end of the third motor to rotate when working, a first motor drives a first front half concave-waist cylinder and a first rear half concave-waist cylinder to rotate forwards when working, and a second motor drives a second front half concave-waist cylinder and a second rear half concave-waist cylinder to rotate backwards when working; the stirring drill bit cuts a soil body at the lower end of the stirring drill bit and stirs the cut soil body with cement slurry when rotating, and the first front half concave-waist cylinder, the first rear half concave-waist cylinder, the second front half concave-waist cylinder and the second rear half concave-waist cylinder cut a soil body at the lower ends of the cylinders and stir the cut soil body with cement slurry when rotating; the first front half concave-waist cylinder and the first rear half concave-waist cylinder cut and stir the left end to form a concave arc head when rotating, and the second front half concave-waist cylinder and the second rear half concave-waist cylinder cut and stir the right end to form a concave arc head when rotating; a cement soil concave pile with the concave arc heads at the left end and the right end respectively is formed when a drill stem presses downwards, and the cement soil concave pile is used as a bearing pile for building foundation engineering.

Description
