Description

Technical Field

[0001] The utility model relates to the technical field of square pile drill bits, in particular to a square pile drill bit suitable for auxiliary forming. Background Art

[0002] In the construction of square piles, the usual method is to pre-drill with a round drill bit and process the square pile into a shape similar to a plum blossom pile. However, this cannot form a standard rectangle. There is still soil and stone at the four corners of the square pile and during its processing because of the offset part of the round drill bit. Therefore, it is necessary to use the excavation wheel connected to the square pile drill bit to trim the corners so that it can be processed into a rectangle. The pick teeth on the surface of the excavation wheel are easily damaged due to long-term contact with the ground, but most of the pick teeth are directly stuck on the excavation wheel, which is too troublesome to replace, time-consuming and laborious. At the same time, because there is a gap between the excavation wheels, some soil and stone will still stick to both sides of the inner wall of the square pile, so it needs to be trimmed twice to make it a standard rectangle.

[0003] Based on this, a square pile drill bit suitable for auxiliary forming is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
