Abstract

A rapid construction device for a prestressed basalt fiber anchor rod, includes a sleeve drill rod and a drill bit; the sleeve drill rod includes an inner and an outer cylinders; a middle of the drill bit is connected to a lower end of the inner cylinder, an edge of the drill is connected to a lower end of the outer cylinder, a constraint hole is defined in the middle of the drill bit for allowing a basalt fiber reinforced plastic (BFRP) penetrating therethrough, a magnetic baffle is arranged at a lower end of the constraint hole to shield the constraint hole, and a plurality of through holes are defined in the drill bit; and the BFRP is pushed to push off the magnetic baffle to lower the BFRP to a set position, and then a space between the inner and outer cylinders is grouted.
