Abstract

Steerable drilling mole (3) which includes a round, hollow body (13), a spraying device (10) situated in front of this body (13) and a high pressure pipe (15) which connects to the spraying device (10), characterised in that the high pressure pipe (15) is at least flexible in the body (13) but nevertheless relatively stiff and it is so held fast in front and at a distance more toward the back by a support (14 and 16) central in the body (13), while the drilling mole (3) has means (22) for bending the high pressure pipe (15) outward in relation to the longitudinal axis of the body (13) between the support in front (14) and the rear support (16) so that the front extremity of the high pressure pipe (15) and therefore the spraying device (10) mounted thereon change direction.
