Sediment extraction pipe sectioning equipment

The utility model discloses sectioning equipment for a sediment extraction pipe. The sectioning equipment comprises a sectioning unit and a linear driving unit. The linear driving unit can drive the sectioning unit to move in the axial direction of the extraction pipe to be sectioned; the sectioning unit comprises a portal frame; the linear driving unit is in driving connection with the portal frame; two cutting assemblies are mounted on the portal frame; the two cutting assemblies are symmetrically arranged on the two sides of the central axis of the extraction pipe. The cutting assembly comprises an electric cutting saw blade making contact with the extraction pipe first and a cutter making contact with the extraction pipe later. The distance between the blade parts of the electric cutting saw blades of the two cutting assemblies is larger than the inner diameter of the extraction pipe and smaller than the outer diameter of the extraction pipe, the distance between the cutters of thetwo cutting assemblies i
