Abstract

The invention discloses a novel geological drill bit manufacturing method. The manufacturing method comprises the following steps of a, manufacturing of a metal tube body, b, manufacturing of a drilling bit, c, assembling of the metal tube body and the drilling bit, d, plug-in mounting of brass strips and coating of welding flux, e, high-frequency welding and f, cooling. Through the process step design, a geological drill bit can be effectively produced and manufactured through the manufacturing method, the process is simple, the manufacturing and machining cost is low, and the manufactured geological drill bit has the advantages of being good in stability and reliability and long in service life.

Description

technical field [0001] The invention relates to the technical field of geological drill bits, in particular to a preparation method of geological drill bits. Background technique [0002] In the construction process of underground foundation projects such as urban high-rise buildings, subway station foundation pit enclosure, river embankment anti-seepage reinforcement and soft soil foundation improvement and reinforcement, a large number of SMW construction method equipment is currently used to construct underground diaphragm walls, that is, multi-axis drilling rigs are used. The technology of continuously drilling, mixing soil and cement slurry in situ and inserting section steel to build underground retaining and waterproof walls, which plays the role of retaining soil and preventing seepage. [0003] Among them, geological drilling rigs generally use geological drill bits to realize soil excavation, and there are various types of geological drill bits in the prior art. H...
