Abstract
The invention relates to an apparatus for laying pipe and/or drainage tile at a desired depth below ground, and a preferred level grade within a trench. The invention maintains the placement of the pipe and, upon substantial completion of backfilling operations of the trench, may be removed for reuse. The invention includes a shaft having an adjustable sleeve and an adjustable pipe-grasping sleeve adapted for engagement to a variety of sized pipes and/or drainage tile. The invention may be securely placed into a trench by manual manipulation of the handles and/or by striking of the strike plate with a hammer. The invention is designed for fast and convenient removal from a trench.
