Combined full-length anchoring pre-stressed anchor rod, stirrer and construction method
The invention discloses a combined full-length anchoring pre-stressed anchor rod, a stirrer and a construction method. The anchor rod comprises a solid steel bar and a hollow grouting anchor rod, wherein the solid steel bar is connected with the head of the hollow grouting anchor rod through threads, the middle section of the hollow grouting anchor rod is flat, a grout return hole is formed in the middle section and is a through hole, a tray is arranged at the tail part of the hollow grouting anchor rod and is fixed through a nut, and the stirrer is matched with the anchor rod to stir the resin anchoring agent. According to the anchor rod, the mine resin anchoring agent end anchoring technology and the hydraulic tunnel hollow grouting full-length anchoring technology are combined, so that the rapid high-strength prestress supporting effect is achieved.
本发明公开了一种组合式全长锚固预应力锚杆、搅拌器及施工方法，所述的锚杆包括实心钢筋和中空注浆锚杆，实心钢筋通过螺纹与中空注浆锚杆的头部相连；中空注浆锚杆的中间段为扁状，在该段上设有返浆孔，返浆孔为对穿孔；所述的中空注浆锚杆的尾部设有一个托盘，托盘通过螺母固定。所述的搅拌器与所述的锚杆配合，实现对树脂锚固剂的搅拌。本发明将矿山树脂锚固剂端锚技术与水工隧洞中空注浆全长锚固技术结合起来，以实现快速高强预应力支护效果。
