Large pipeline collapse repairing structure

The large pipeline collapse repairing structure comprises a pipeline, a blocking piece used in cooperation with the pipeline is arranged at the collapse position of the pipeline, the blocking piece is obliquely arranged and is in butt joint with the pipeline, the blocking piece is used in cooperation with a pipeline body to block soil above the pipeline, and a soil inflow preventing blocking structure for preventing the soil from flowing into a repairing part again is formed. And soil at the collapsed position is cleaned, then the corresponding pipeline body is sleeved with a repairing part matched with the pipeline body, and a pipeline matching corresponding repairing structure is formed. According to the utility model, through the arrangement of the soil inflow prevention blocking structure for preventing the soil from flowing into the repair part again, the collapse part of the pipeline can be repaired only by sleeving the repair piece into the pipeline corresponding to the collapse part during repair, so
