A ditch backfilling device and apparatus therefor are disclosed. In particular, the ditch backfilling device includes a mainframe for supporting a compartment for storing the backfill material and a screening system for sorting and directing the backfill material into a ditch. The backfilling device includes a support for holding a roll of warning tape and an application roller for placing the unrolled portion of the warning tape above a uniform structure, such as a pipeline, within a layer of backfill material in the ditch. The warning tape is thereafter buried in subsequent layers of backfill material poured by the backfilling device. The backfilling device also includes a guide structure which is configured to follow the surface of the uniform structure. The guide structure positions a conduit adjacent the uniform structure for burial in the backfill material. The conduit may contain cables for the transmission of communication information or operating instructions.
An apparatus attachable to a backfilling device for positioning a conduit adjacent a uniform structure within a ditch being backfilled, comprising:
A device for backfilling a ditch and installing a conduit therein, comprising:
A device for backfilling a ditch having a uniform structure therein and for positioning a conduit adjacent the uniform structure, comprising:
