深部软岩巷道三维预应力钢绞线壁后充填支架支护体系
摘要：
本实用新型公开了一种深部软岩巷道三维预应力钢绞线壁后充填支架支护体系，包括支架、锚杆锚索和三维预应力钢绞线系统，支架形成支护体系的内承载结构层，锚杆锚索形成所述支护体系的外承载结构层，所述锚杆锚索伸入到围岩中，支架和围岩之间填充有填充材料形成中间承载结构层，支架和锚杆锚索之间通过三维预应力钢绞线系统做环向、径向和轴向的三维连接，并施加预紧力。该体系整体性好、支架受力状态好、材料利用率高、劳动强度低。
摘要（英）：

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.
