Abstract (en)
The invention relates to the making of earth zones by means of a machine equipped with a movable arm (2), with means (20, 22, 24, 26) for distributing a granular material and with ejectors (8) supplied with textile yarns (10). According to the invention, the machine is equipped, furthermore, with a supporting frame (6) which is removable from the arm head (2) and on which is mounted a carriage forming a support for the ejectors (8) fastened to a shaft which is mounted so as to oscillate about its axis and, moreover, is subjected to an alternating translational motion parallel to its axis of oscillation. The carriage can also be movable in translational motion perpendicularly to the axis of oscillation of the ejector-carrying shaft. The invention is used for making reinforced earth zones. <IMAGE>
