  • Patent number: 8789722
    Abstract: A bedding box has a container formed by sloped end plates and side plates joined to a bottom plate, with gusseted wing plates reinforcing the side plates. The wing plates extend outwards from the container to facilitate loading. A frame attaches to each of the end plates, one frame having horizontally-extending, vertically-spaced apart bars to allow the bucket of a compact excavator to be wedged therebetween to lift the bedding box, while the other end serves to attach one or more support brackets that can be lifted by a scraper blade of the excavator, allowing support at both ends of the bedding box for transportation over uneven terrain. Skids can be affixed to the bottom plate to reinforce it, to facilitate dragging the bedding box, and to facilitate lifting the bedding box from one end with a forklift.

    Abstract: An apparatus for laying underground electric cables, in particular for high-voltage lines, comprises a vehicle (2) towable along a trench (3) and carrying, on a first van (4), a first deposition unit (12) adapted to form a base layer (13) of inert material for heat dissipation at the trench bottom. Mounted on the first van (4) is a guide structure (20) engaging the cable (21) for laying it on the base layer (13) previously compacted by a vibrating plate (18). A second van (5) carries a second deposition unit (30) forming a covering layer (31) of inert material upon the previously laid-down base layer (13) and cable (21).

  • Patent number: 6345933
    Abstract: An underground storage tank with backfill deflectors is provided to permit installation of the storage tank underground without requiring any workers to enter the excavation. The backfill deflectors are preferably elongate, and generally the same length as or longer than the storage tanks with which they are used and are installed on the bottom of the excavation on either side of the tank. The deflectors have walls which are sloped or inclined in a direction which tends to direct backfill dumped thereon underneath the storage tank. Desirably, the deflectors direct the backfill under the tank without requiring any of the workers to enter the excavation to shovel the backfill underneath the lower portion or haunches of the tank. After a sufficient level of backfill is introduced into the excavation and directed under the tank by the deflectors, the backfill is vibrated to achieve a compacted backfill under the tank which is sufficient to support the tank.

  • 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: 6302257
    Abstract: A self propelled vehicle for transport and placement of an onboard supply of fill material in an onboard hopper. The hopper is connected to said vehicle at a point operatively positioned to discharge fill material placed therein on a conveyor belt mounted to a support structure. At the distal end of the conveyor where the material is discharged a flow director is operatively attached to the support structure to receive the flow of fill material carried by said conveyor from the hopper. The flow director bifurcates the stream of fill material allowing the operator to place more or less of the fill in two streams using a plurality of independently adjustable channeling ramps. The hopper is optionally adjustable from an angle normal to the vehicle to allow for adjustment in the vehicle center of gravity on grades. The flow director can also be configured for attachment to existing conveyors to increase their utility or used as part of the entire self propelled device in a single unit.

  • Patent number: 6280119
    Abstract: The invention contemplates a working implement, for use with an excavating type machine, which semi-automatically brings a pipe section to a specified grade, slope, and line for emplacement in a line of pipe sections to be laid on the specified grade slope and line. The implement is rigidly mounted to the excavation machine whereby the position of the implement can be maintained within narrow tolerances while the pipe section is linearly inserted into a previously laid pipe section, and can be retained at the specified grade, slope, and line while fill material is emplaced and consolidated about and under the pipe, with sufficient density that the pipe can be released without the pipe moving outside normal tolerances of the specified grade, slope and line.

  • Patent number: 6158925
    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.

  • Patent number: 6125558
    Abstract: A padding machine (10, 100) is disclosed which is capable of separating materials in a spoils bank beside a trench into coarser materials, which are redeposited in the spoils bank behind the machine, and finer materials which are conveyed to the trench for padding the pipeline. The machine includes a conveyor with a conveyor chain which moves around the perimeter of the machine. Material caught by the scraper blade (28) is conveyed by the conveyor chain along a belly pan (70) and thereafter over a plurality of grizzly bars (72). Coarser material which will not pass through the grizzly bars is conveyed by the conveyor chain (56) to the rearward end of the machine and dumped off the rearward end of the machine back to the ground. The finer materials passing through the grizzly bars are again separated by a vibrator unit (76, 104).

  • Patent number: 6095721
    Abstract: A method for the penetration of a body (8), having a leading edge (21) and an inclined ground contacting surface (C, D, E) extending upwardly therefrom, into a porous ground material, the pores of the ground material being at least partially filled with water. The method comprises applying a driving force to the penetrating body in the direction of penetration, and discharging from the penetrating body (8) at least one flow of high-pressure gas to the inclined surface so as to facilitate the penetration of the body. Moreover, a penetrating body (8) and a plough assembly both of which can be used in the method. The method and equipment may e.g. be used for embedding drain tubes, pipes, cables or similar objects into a ground material also at a relatively great depth larger than 100 cm. Moreover, the embedding can be performed by employing a relatively high speed and can be performed at a relatively low energy consumption.
