The present invention relates to an apparatus for firmly positioning in a trench and securing against movement while fill is added to the trench an underground utility pipe and means for marking the utility pipe. More particularly, the present invention relates to an underground positioning and anti-movement apparatus in the form of an underground stake adapted to be driven into a base fill, that includes an integral preferably curvilinear-shaped pipe engaging member which engages the outer surface of an underground pipe to secure the pipe in position above the base fill at the bottom of the trench while additional fill is added to the trench. The present invention also includes at least one integral receptacle located longitudinally on the stake body above the pipe engaging member which receives, supports and secures tracer -%vire, caution tape, or other marking means used to facilitate identification and location of the secured underground pipe and which allows placement of the marking means at a location above the pipe before the trench is filled so that the trench may be filled without disturbing the position of the marking means in relation to the secured pipe and without having to lay the pipe and marking means at different stages in the fill process. The current invention may also include an integral anti-removal member which extends from the bottom of the stake, compresses when pressed into the underlying supporting base fill, and expands and scoops up base fill to impede movement of the stake when upward force is applied to the stake body.
