Structure and method for quickly treating differential settlement of bridgehead

The invention relates to a structure and a method for quickly treating differential settlement of a bridgehead, a geogrid, a frame, a hollow steel pipe, a copper rod, an electric heating wire, a copper rod, a humidity sensor and a data line are buried during construction of a bridgehead structure, when differential settlement of a road surface occurs at the bridgehead after operation, a grouting pipe is mounted at the hollow steel pipe on one side of a roadbed, and the grouting pipe and the data line are connected in sequence. The generator is started, humidity changes are monitored, the height of an existing roadbed is observed through a scale, the height needing to be lifted is estimated, after the electric heating wire is heated, the steel pipe is heated to expand, soil around the steel pipe is heated to expand, and meanwhile, the soil inside the roadbed is integrally lifted through grouting; a humidity sensor monitors and prevents slurry leakage, a channel on the lower portion of the geogrid enables slurr
