ABSTRACT:
An apparatus for depositing fill material over a pipeline. A wide-track carriage is provided for straddling the pipeline trench, and this includes a shaker screen mechanism for screening aggregate fill material, such as excavated native spoils. The screened fill material is fed into the trench via a pivoting conveyor which is controlled by means of a pivotable and extensible boom. A mix auger is also provided for mixing water and cement with the fill material to form a cementitious Controlled Low Strength Material fill in those installations where this is needed.
