Cable burying apparatus
First Claim
1. Apparatus for burying a plurality of cables in a previously excavated trench in a predetermined spatial relationship to each other surrounded by an initial backfill material, the apparatus comprising:
- a cable supply vehicle for transporting a plurality of reels of cable for emplacement in the previously excavated trench;
cable guide means for receiving the plurality of cables from the cable supply vehicle and for guiding those cables into a cable bundle;
a sanding sled positioned within the previously excavated trench for receiving the cable bundle from the cable guide means, the sanding sled including forward guide means having a plurality of guide members for receiving the individual cables of the cable bundle in a predetermined spatial relationship to each other and rear guide means positioned adjacent the rearward portion of the sanding sled, the rear guide means having a plurality of guide members in substantial alignment with the guide members of the forward guide means and being positioned for receiving the individual cables of the cable bundle from the forward guide means and for maintaining the individual cables of the cable bundle substantially parallel to but spaced away from the side walls and bottom of the previously excavated trench and in the same spatial relationship to each other as established by the forward guide means, the sanding sled further including a sand chute conveying the initial backfill material, the sand chute being positioned between the forward and rear guide means and over the plurality of individual cables extending therebetween, the sand chute being adapted to convey the initial backfill material for flow surrounding the plurality of individual cables that extend below the sand chute in the area between the forward and rear guide means, the sanding sled further including adjustable backfill levelling means positioned adjacent the rear guide means for permitting the backfill material to be deposited into the previously excavated trench to a predetermined depth surrounding the plurality of individual cables of the cable bundle in their predetermined spatial relationship to each other; and
tractor means coupled to the sanding sled for pulling the sanding sled along the trench.

Abstract
An apparatus for simultaneously burying a plurality of cables in a previously excavated trench in a spaced relationship to each other and for protectively surrounding those spaced apart cables with sand comprises a cable supply vehicle from which the plurality of cables is unreeled, a cable guide boom assembly for spatially aligning the cables, a sanding sled that is positioned within the trench for guiding the cables into the desired spatial relationship and for distributing sand to a desired depth around the plurality of cables, a sand supply vehicle for providing a source of sand at a controlled rate of flow to the sanding sled, and a tractor vehicle for pulling both the sand supply vehicle and the sanding sled along the path of the trench.
