Technical Field
[0001] The utility model relates to the technical field of hydraulic square pile drill bits, in particular to a hydraulic square pile drill bit which can quickly form square holes. 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 are still soil and rocks at the four corners of the square pile and in the processing due to the offset of the round drill bit. In previous construction, this part of the remaining soil and rocks is usually trimmed manually. This has the disadvantages of low labor efficiency, high labor intensity, and high danger in the construction environment. The hydraulic square pile drill bit replaces this part of the manual work, so as to achieve the purpose of reducing the labor intensity of workers, improving the working environment of workers, and improving labor efficiency. However, when the square pile drill bit is trimming, the rotating excavation wheel breaks the inner wall of the square pile. At this time, the broken rock will generate a lot of dust, which will pollute the air and seriously affect the work vision and health of the workers.
