Deep soft rock roadway three-dimensional prestress wire backfilling support retaining and protecting system

The utility model discloses a deep soft rock roadway three-dimensional prestress wire backfilling support retaining and protecting system which comprises a support, anchor rods, anchor ropes, and a three-dimensional prestress wire system, wherein the support forms an inside-bearing structure layer of the retaining and protecting system, the anchor rods and the anchor ropes form an outside-bearing structure layer and extend into surrounding rock, a middle-bearing structure layer is filled between the support and the surrounding rock, the middle-bearing structure layer is filled with filling materials, and the support, the anchor rods, and the anchor ropes conduct annual, radial and axial three-dimensional connection through the three-dimensional prestress wire system and exert pretightening force. The deep soft rock roadway three-dimensional prestress wire backfilling support retaining and protecting system has the advantages of being good in integrity and stress state of the support, high in material utilization rate and low in labor intensity.
