The invention provides a fixed slag discharging device for cleaning the inner wall of a drill bit of a rotary excavating drill and a construction technology of the fixed slag discharging device. The fixed slag discharging device for cleaning the inner wall of the drill bit of the rotary excavating drill comprises a mounting part; the cleaning part is arranged on the mounting part, and the cleaning part completely or at least partially extends into the drill bit to clean the inner wall of the drill bit. The device is simple in structure, stable, reliable and high in operability; the construction method is easy to operate, high in speed and remarkable in effect; the installation time is short, the efficiency is high, and a large amount of labor cost and time cost can be saved; the fixed base is arranged, so that the stability is obviously improved, the device is not easy to collapse and move under external force, and the safety is relatively high; through the drill bit auxiliary slag discharging device, the swinging frequency of the power drill bit in a conventional construction method is greatly reduced, and then noise pollution is reduced.
Description
technical field [0001] The invention relates to the technical field of rotary drilling cleaning, in particular to a fixed slag unloading device for cleaning the inner wall of a rotary drilling drill bit and a construction process thereof. Background technique [0002] In the construction process of underground engineering, as a kind of comprehensive drilling machine, the rotary drilling machine has the characteristics of fast hole forming speed, less pollution and strong mobility. To a certain extent, it meets the requirements of use, but there are also the following disadvantages: ①The soil is squeezed and dense, and it is easy to stick to the inner wall of the drill bit; , affecting the construction progress. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, the first aspect of the present invention provides a fixed slag unloading device for cleaning the inner wal...
