APPARATUS FOR LAUNCHING A SOIL BURROWING MOLE

摘要

Apparatus and method are disclosed for launching a linear impact subsoil penetrator (mole). The apparatus includes a support platform which can be positioned to provide a selected angle of attack for the mole relative to the soil surface. The linear impact drive of the mole is started; and a restraining force is applied by the apparatus to the sides of the mole to create artificial tunnel traction and prevent the backward slip of the mole. This insures that operation of the mole's linear propulsion system will produce only forward motion and move the mole's nose into the soil.
