Abstract

1. A boring bit for forming boreholes, acting by lateral pressure on the ground, comprising a boring bit body (2, 15) and a central coupling tube (1, 14) closed at its end which is rotated and possibly subjected to a force along its axis, characterized by the fact that the head has at its end two helical cylinder walls (5, 6), extending from the central coupling tube, and whose axis is parallel to the axis (11) of the boring bit, facing each other, but offcentered with respect to each other and with respect to the axis (11) on the boring bit, disposed, taking into account the direction of rotation of the boring bit for forming a drill hole, so as to push the earth outwardly and so as to compress it laterally outwardly by their external face, because of the offcentering thereof, the orientation of the helical portion which they form respectively being that which corresponds to driving the boring bit into the ground for said rotation.
