Abstract: Apparatus for driving an open-ended conductor pipe into the ground. The apparatus includes, in combination, an open-ended conductor pipe capable of being driven into the ground, a drill string, a device for pumping fluid through the drill string, an arrangement for supporting the conductor pipe on the drill string, and a reciprocable impact driver supportable by the drill string within the conductor pipe. The apparatus further includes a device for reciprocating the reciprocable impact driver using fluid pumped through the drill string, an anvil capable of transferring the percussive force of the reciprocable impact driver to the conductor pipe, and jets for jetting fluid into the lower portion of the conductor pipe.
