An anti-collapse grouting consolidation system including: a grouting pump; an outer flat drill rod; a drill rig that clamps the outer flat drill rod; a sealing device, sheathed on the outer flat drill rod at the orifice of a drill hole, ensuring the outer flat drill rod is sealed with the orifice of the drill hole; and a jet grouting drill bit with bi-directional rib wings. The grouting pump jets slurry into the drill hole in a static osmotic manner through the jet grouting drill bit. A method of using an anti-collapse grouting consolidation system includes, among other things, injecting quick-setting slurry; sealing an orifice hole of the drill hole by an orifice sealing device; and keeping an anti-collapse jet grouting drill bit with bi-directional rib wings repeatedly moving up and down and rotating at a repair segment to repair the repair segment.
