Pier top index pull-back method bridge deviation rectifying and resetting system and construction method

The invention discloses a pier top index pull-back method bridge deviation rectifying and resetting system and a construction method. The pier top index pull-back method bridge deviation rectifying and resetting system comprises a bridge head combined stand column anchoring device, a force exerting device for providing resetting loads, a pulling force conversion device, a deviation rectifying steel strand and a pier top anchoring device. The bridge head combined stand column anchoring device provides strong anchoring force by combining and reinforcing a plurality of adjacent wave-shaped guardrail plate stand columns at a bridge head into a whole. The tension conversion device achieves axial transmission between traction force and anchoring reaction force, can stabilize the space posture of the tension conversion device, and can effectively prevent the deviation correction steel strand from being sheared and damaged due to overturning of the conversion device in the deviation correction process. The tension co
