Abstract: A rock breaking seismic source and active source three-dimensional seismic combined detection system uses a tunnel boring machine for three-dimensional seismic combined detection by active seismic source and rock breaking seismic source methods. Long-distance advanced prediction and position recognition of a geological anomalous body are realized using the active source seismic method. Machine construction is adjusted and optimized according to the detection result; real-time short-distance accurate prediction of the body is realized using the cutter head rock breaking vibration having weak energy but containing a high proportion of transverse wave components as seismic sources and adopting an unconventional rock breaking seismic source seism recording and handling method. An area surrounding rock quality to be excavated is represented and assessed. A comprehensive judgment is made to the geological condition in front of the working face with the results of active source and rock breaking seismic source three-dimensional seismic advanced detection.

Abstract: 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.
