Description

technical field

[0001] The invention relates to engineering machinery technology, in particular to a rectangular hole-forming drill bit. Background technique

[0002] At present, there is no drill bit that can form a rectangular hole, and the drilled hole is not easy to be close to the adjacent building, and the surface of the adjacent building cannot be cleaned. The large inclination of the drilled hole makes the function of the bored pile narrow, which is very important. To a great extent, it restricts the construction of some major projects and directly affects the development of the national economy. Contents of the invention

[0003] The object of the invention is to provide a rectangular hole-forming drill bit with small drilling slope, which can be close to the adjacent buildings, can remove the surface soil of the adjacent buildings, and does not damage the adjacent buildings. The object of the present invention is achieved like this, it comprises transmission ass...
