The utility model discloses an elastic sealing type split expansion joint, and relates to the technical field of expansion joints. The expansion joint comprises an expansion joint mechanism, a connecting mechanism and a fixing mechanism, two connecting mechanisms are symmetrically arranged on the peripheral side surface of the expansion joint mechanism and are clamped with each other; the fixing mechanisms are located at the two ends of the expansion joint mechanism and clamped with the expansion joint mechanism. Wherein the expansion joint mechanism consists of an outer ring expansion cylinder and an inner ring expansion cylinder; and the inner ring expansion cylinder is positioned in the outer ring expansion cylinder and is sleeved with the outer ring expansion cylinder. The expansion joint is connected with the first weight disc in the outer ring expansion cylinder through the fixing mechanism, and is connected with the second weight disc in the inner ring expansion cylinder through the fixing mechanism, s
