Abstract: A method of inserting a preceding element and then a following element in the ground, along a calculated path, in order to construct a work, the method including: a step of determining an absolute positioning error of a preceding element relative to the nominal position at which the preceding element ought to have been inserted; and a step of automatically guiding the inserter arm towards a target position at which a following element is to be inserted as a function of the absolute positioning error determined for the preceding element in such a manner as to reduce the positioning error of the following element relative to the preceding element.

Abstract: A device for inserting elements into the ground in order to carry out works includes a positioning mechanism. The positioning mechanism includes an upper panel which is fixed to the chassis of a vehicle for transporting the insertion device, a movable plate to which an insertion arm is fixed, and at least six jacks which can be controlled so as to allow movement of the movable plate relative to the upper panel with six degrees of freedom, each jack being directly fixed, at one side, to the upper panel and, at the other side, to the movable plate of using connections which have three degrees of freedom in terms of rotation.
