Abstract: A hydraulic jack expansion-type rotary penetration device for a circular pipe comprises: a rotating head which receives torque from the outside; one or more hollow shafts arranged in series downward along the central axis of the rotating head; shaft-connection socket which interconnect the first hollow shaft which is connected to the rotating head with the remaining adjacent hollow shafts, to thereby transmit the torque of the rotating head; and one or more clamp modules which are installed in the hollow shafts and pressed against the inner surface of the circular pipe by hydraulic pressure generated in the rotating head to thereby generate clamping force.

Abstract: Methods and devices for a boring and laying device for the trenchless laying of a pipeline, including a boring head, wherein the boring head includes a connection for a pilot bore linkage, wherein a pilot bore is produced from a starting point to a destination point along a predetermined boring line, a pump for suctioning and conveying away the drillings, a conveying portion behind the boring head in which at least one suction element for receiving and conveying away drillings, and a connecting portion including a connection for the pipeline. The pilot borehole is expanded, and simultaneously the pipeline is laid by pulling the pilot bore linkage out of the borehole on one side and/or by pushing the pipeline into the borehole, wherein drillings are hydraulically received behind the boring head of the boring and laying device and conveyed away out of the borehole with a pump.

Abstract: Methods, apparatus, and systems providing enhanced feed rate control of tubing and conduit feeds by a powered feeder to an in-ground placement device moved across the ground by a steerable vehicle. In one aspect, ground speed of the vehicle is sensed. Feed motor speed is correlated to length of tubing or conduit estimated to be fed per feed wheel revolution by the feed motor. A controller adjusts feed motor speed to match ground speed to feed rate. In another aspect, instead of estimating feed rate by feed wheel rotation, actual speed of movement of the tubing or conduit is sensed. Feed motor speed is automatically and dynamically adjusted to match ground speed to tubing or conduit speed. In either embodiment, sensing of ground speed can be used to sense starting and stopping of the vehicle. This can be used to turn the feed motor on or off. In either embodiment, integration with a precision agriculture intelligent controller can allow operator control right from the precision ag display.

Abstract: The invention relates to a system and method for containing and mitigating spills and leaks from pipelines. According to one embodiment, the system comprises a pipeline for transporting a liquid; a barrier layer comprising material impermeable to the liquid; a trench excavated with sufficient depth and width to accommodate at least the pipeline as well as the barrier layer; two berms; and backfill. The berms are substantially parallel and positioned on either side of the trench. The barrier layer is disposed to cover the trench and berms, reaching at least the ridgeline of the berms. The pipeline is disposed within the trench above the barrier layer. The backfill is placed on top of the pipeline and the barrier layer, and the backfill is graded to form a grade bridging the ridgelines of the berms.
