Based Tension unbonded prestressed reinforced earth art anchor

The present invention discloses a tensioning anchoring device based unbonded prestressed reinforced earth techniques, including anchoring screw (3), side flaps (4), anchor nut (7), further comprising a support (5) the bracket (5) through said screw anchor (3) of the oblique support frame (6) disposed and fixed on the anchor screw nut (9) (3) is fixed to the side flap ( 4); a hydraulic jack (13) is provided at the top of the outer arm (5), by passing through the bracket (5) of the tensioning screw (12) and a tensioning screw (12) connected to the anchor set screw (3) tendon sheet (1) for tensioning; post-tensioning anchor tighten the nut (7) to complete the anchorage. The invention achieves the integration and accurate control of the tension of the reinforcement material and anchoring the prestressing size, greatly improving the efficiency of tension, effectively reducing the prestressing loss after anchoring, improve construction quality and reduce economic costs.
