Abstract

The invention discloses a preparation method for an anchorage reaming bit. The anchorage reaming bit comprises a drill rod, wherein a tip part is arranged at the front end of the drill rod; reaming wing tool grooves are symmetrically formed in the two sides of the tip part; a reaming wing tool is arranged in each reaming wing tool groove; each reaming wing tool is of a V-shaped structure; the tailend part of each reaming wing tool is installed in the corresponding reaming wing tool groove through a rotary shaft; adjustment through holes are formed in the corresponding tip parts between the front end parts of the two reaming wing tools; and tension springs tensioning the two reaming wing tools are arranged in the adjustment through holes. The reaming wing tools can be limited from being excessively expanded through support columns of the reaming wing tools, the reaming wing tools lose the protection of the reaming wing tool grooves and are liable to be damaged in the case of too largeexpanding angles of the reaming wing tools; and the service life of the bit is prolonged by 2-5 times through the bit structure.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for preparing an anchoring reaming drill bit. Background technique [0002] Drilling is carried out with a drilling rig, and due to the influence of the drill bit, only holes with unique apertures can be drilled. Holes with a single diameter cannot meet the construction requirements in some special cases. For example, in rock formations that need to be blasted, people hope that the inside of the hole where the explosives are placed has a larger cross-sectional area, and it is best to have a structure where stress concentration occurs, so that a weak surface appears in the rock formation, thereby enhancing the blasting effect. For another example, when making anchor rods and cables, people also hope that the cross-sectional area of ​​the inside of the hole is larger than the cross-sectional area of ​​the opening of the hole, thereby increasing the fricti...
