  • Patent number: 6505406
    Abstract: A guide method for guiding a device that is designed to insert elements into the ground in order to make a structure. The method includes the steps of: establishing topographical points and determining the coordinates of these points in an X, Y, Z frame of reference; putting a measuring station in place in the vicinity of a location where the structure is to be made and determining the X, Y, Z position of the measuring station with reference to one or more topographical points; determining, by means of the measuring station, the distance and the angle between the insertion device and the measuring station; calculating the position of the device by means of the measured distance and the known position of the measuring station; and displacing the insertion device so that the elements are in register on the insertion axis with given positions where the elements are to be inserted into the ground.
