The utility model relates to a split-type expansion joint used to block leakage. After producing leakage, a prior expansion joint just can be exchanged after breaking flow and releasing pressure). Therefore, the split-type expansion joint used to block leakage is characterized in that the split-type expansion joint used to block leakage comprises two split sliding rings and a split outer ring sleeve, the inner diameter of the sliding ring is greater than or equal to the outer diameter of a distribution pipeline, the outer diameter thereof is less than or equal to the inner diameter of a corresponding part of the outer ring sleeve, the outer ring sleeve is hooped on the sliding rings by a bolt or a screw, packs the whole leaked expansion joint, a sealing pad is arranged between the sliding rings and the outer ring sleeve, and the sliding rings and the outer ring sleeve can move corresponding to the axial direction when stressing. The split-type expansion joint used to block leakage has the advantages of simple
