Flexible drainage pipeline backfilling inner supporting device

The utility model relates to a flexible drainage pipeline backfill inner supporting device which comprises more than two supporting single bodies, each supporting single body comprises a trolley and at least three supporting rods borne on the trolley and used for supporting the inner wall of a pipeline, and every two adjacent supporting single bodies are connected through a transverse connecting steel pipe. The supporting single bodies are arranged at intervals, a supporting system is formed in the flexible pipeline, and when the device is used, the device is directly placed in the flexible pipeline, and the supporting rods are used for supporting and fixing. And during backfilling operation, deformation of the flexible pipeline is limited, deformation of the flexible pipeline is prevented, it is guaranteed that the deformation amount of the flexible pipeline is reduced within an allowable range, and later-period operation safety of the pipeline is guaranteed. 本实用新型涉及一种柔性排水管道回填内支撑装置，包括两个以上支撑单体，每个支撑单体包括小车和承载于小
