  • Patent number: 9169618
    Abstract: A backfilling device for backfilling an open trench and padding a pipe within the trench has a lateral earth moving device and a sifting device. The backfilling device is attached to a tractor that moves the lateral earth moving device into a backfill spoil pile adjacent to the trench with the sifting device located above the trench. The lateral earth moving devices moves the backfill spoil material laterally into a rotating drum of the sifting device. Smaller particles of the backfill material fall through the rotating drum, which is also vibrating to backfill the trench and pad the pipe with backfill fines. The oversize debris in the backfill material continues to move laterally and falls out the end of the rotating drum to form a pile of large piece backfill material on the side of the trench opposite from the backfill spoil pile.

  • Patent number: 7870683
    Abstract: A method for trenching below the water table in environmentally sensitive areas such as the Florida Keys is shown. A first pass made by a trencher digs a first trench from the surface to the water table. During the first pass, relatively dry spoil is removed from the first trench. Next, a much deeper second trench is dug below the first trench; however, wet spoil remains in the now combined first and second trench, the combined first and second trench being large enough to accumulate the wet spoil with expansion. Thereafter, the combined first and second trench may be filled with the relatively dry spoil, packed and driven upon. Later, the packed spoil may be removed and water pipes, electric cables, sewer lines or the like buried in the trench. According to the requirements of the work area, the spoil may be used to partially fill the combined first and second trench or be hauled away.

  • Patent number: 6418644
    Abstract: The present invention relates to a method for padding ground below a duct (1) using excavated soil (2), wherein said method uses a vehicle (6) that comprises a soil feeding organ (13), a transport organ (14) and soil compacting organs (104, 105). The vehicle moves along a ground path (16) which is formed by the soil feeding organ (13) as it collects excavated soil (2). This method allows for a reliable orientation of the soil compacting organs (104, 105) relative to the duct (1), wherein said compacting organs apply a force on the soil previously deposited in the trench (4). This invention also relates to a device which is used for padding ground below a duct (1) and comprises a device (106) for hanging a soil-compacting mechanism (103) to the vehicle (6). The device (106) includes a disconnection mechanism (153) that enables the cyclic displacement of the rammer-type compacting organs (104, 105) in the displacement direction of the vehicle (6).

  • Patent number: 6318930
    Abstract: A trench-padding method and apparatus provide a more efficient, cost efficient process of obtaining a maximal amount of padding material from material excavated from a trench, and where selected, provide for trenching. The trench-padding apparatus includes a lead assembly that includes a feeder housing having a front rotating unit with protrusions. The feeder housing may be configured to excavate the trench or alternatively, to scoop up previously excavated material. The front rotating unit is attached to a frame of the trench-padding apparatus immediately in front of an elevator device, and the front rotating unit forces clumps of the excavated material between the front rotating unit and a base of the feeder housing to aid in reducing clump size. The method operates in the manner of the trench-padding apparatus.

  • Patent number: 6273637
    Abstract: A compactor including a forward and rearward compaction wheel each rotatably supported on a support arm and pivotally connected to a main frame. The forward compaction wheel is pivoted to a position aligned forwardly of and positioned below the rearward compaction wheel when in an operating position. A pair of diverter panels are connected to the frame and extend longitudinally on opposing sides of the rearward compactor wheel to divert fill dirt towards the compactor wheels. Each diverter panel has a diverter wing pivotally connected thereto with the diverter wings diverging outwardly and forwardly. The diverter wings are pivotally connected at a point of the forward compaction wheel and proximal thereto. The diverter panels are preferably parallel to one another and extend rearwardly beyond the rearward compaction wheel. The diverter wings preferably extend forwardly beyond the forward compaction wheel.

    Abstract: A clam bucket of the present invention has a first and a second bucket halves, each bucket half includes a first and a second side wall, a bucket back wall, and a bucket connecting plate. Optionally, at least a portion of each of the two side walls may be made of a side wall screen. The bucket back wall is rigidly connected between the first and the second side walls and extends from the bucket top edge to the bucket digging edge. At least a portion of the bucket back wall is composed of a back wall screen. The side wall screen, if used, and the back wall screen should be positioned so as to allow padding material to pass through the screen but prohibit the passage of stones through the screen. The bucket connecting plate is rigidly connected to the outside of the bucket back wall and positioned between the first side wall and the second side wall so that connection to a backhoe can be made.
