Abstract

The invention discloses a rectangular drill rig. An eccentric body A is fixed at the lower part of a drill rod A and is arranged in a shaft sleeve on the left side of a rectangular knife A; an eccentric body B is fixed at the lower part of a drill rod B and is arranged in a shaft sleeve on the right side of the rectangular knife A; an eccentric body C is fixed at the lower part of a drill rod C and is arranged in a shaft sleeve on the left side of the rectangular knife B; an eccentric body D is fixed at the lower part of a drill rod D and is arranged in a shaft sleeve on the right side of the rectangular knife B; an eccentric body E is fixed at the lower part of a drill rod E and is arranged in a shaft sleeve on the left side of a rectangular knife C; an eccentric body F is fixed at the lower part of a drill rod F and is arranged in a shaft sleeve on the right side of the rectangular knife C; an eccentric body G is fixed at the lower part of a drill rod G and is arranged in a shaft sleeve on the left side of a rectangular knife D; an eccentric body H is fixed at the lower part of a drill rod H and is arranged in a shaft sleeve on the right side of the rectangular knife D.

Description

technical field [0001] The invention relates to a mixing drill, in particular to a rectangular mixing drill used in building foundation engineering. Background technique [0002] At present, the mixing drilling rig used in building foundation engineering is to use multiple mixing bits to mix with cement slurry to form a plurality of lapped piles. The thickness of the overlapping part is smaller than the diameter of the circle, so the anti-leakage Ineffective. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides a rectangular mixing drill. [0004] The present invention is achieved through the following technical solutions: [0005] A rectangular mixing drilling rig, a plurality of drill rods are arranged in double rows, the drill rods A, B, C, and D are arranged in a row in the front row, and the drill rods E, F, and D are arranged in a row in the rear row. Drill pipe G, drill pipe H, drill bit A is set at the lower e...
