ABSTRACT:
A groundline stabilizing device for stablizing in-ground pipes in their original in-ground relationship has a spacing bar with clamp members fixed to its ends for receiving the pipes in transverse alignment with respect to the bar, and a plate fixed to the bar in parallel relationship to a plane passing through the bar and the pipes received in the clamps which responds to shifts in the earth to stabilize the position of the pipes relative to the surrounding earth, minimizing radial shifts on one pipe in relation to the other.
