Optical fiber sensor structure for monitoring corrosion of reinforced concrete

The utility model discloses an optical fiber sensor structure for monitoring corrosion of reinforced concrete, which comprises monitoring round steel, a mortar layer is formed outside a monitoring area of the monitoring round steel through mould pouring mortar packaging, and a sensor structure is arranged inside the mortar layer. The sensor structure comprises three pressing seats which are tightly attached to the upper side, the lower side and the left side of the outer wall of the monitoring round steel, the inner side faces of the three pressing seats are arc faces with the same shape as the outer wall of the monitoring round steel, the outer side faces of the three pressing seats are arc faces on the same circumference, and the front ends and the rear ends of the outer side faces of the three pressing seats are each provided with an arc clamping seat. Wherein the arc-shaped clamping seats are respectively clamped and pressed at the front ends and the rear ends of the outer side surfaces of the three press
