The present invention discloses a device and a method for large-scale flow solidification treatment of dredged sediment in a pipeline without a yard. The device includes a dredger, a treatment unit and a use terminal that are communicated in sequence, where the dredger is connected with the treatment unit by adopting transportation units, a mud pump is arranged between the transportation units and the dredger to provide power, a plurality of transportation units are communicated in sequence by adopting relay pumps, the treatment unit includes a mixing system, a monitoring system and a data processing and control system, and the device is also provided with an air pump. The method for the flow solidification treatment of the sludge in the pipeline, provided in the present invention, fundamentally changes the mode where the traditional dredging engineering needs to set up a large number of sludge yards first, and then uses solidification treatment equipment for stirring and mixing treatment, which saves land, and does not have the problem of environmental pollution of yards, and therefore, the method has wide applicability; and a device and a method for mixing sludge and a solidifying material in a pipeline are provided, the injection speed of a solidifying agent is precisely controlled, the mixing effect is good, the emphasis is on the grading and judging standards of pipelines, and corresponding solutions are given.
