Abstract
The present invention consists of a steel element with cylindrical cross section (tube), to which is welded a steel sheet of helical trend with a definite pitch which allows it to be inserted into the ground by simple rotation in a clockwise direction, accompanied by slight pressure. The special quality of this anchoring pile is that it is able to move through all loose ground, even that of coarse texture, by simple rotation, screwing itself into the ground. The driving can be accomplished through a simple jack wrench or for ground that is harder to penetrate by the use of small internal combustion motors (of the drill type) or pneumatic motors. Once the anchoring pile is inserted in the ground, it can be injected with cement grout which, flowing back from the lower end of the pile, and moving upward through appropriate openings, creates an anchoring bulb between the spiral and the ground, improving the resistance to being removed. The anchor is heat-treated with double galvanisation to permit a long lifetime. The pile can reach depths of several metres thanks to screw-on extensions which are likewise provided with a spiral. The anchor pile can also be made simply with cylindrical rods of solid cross section, having the spiral wound and welded on it, such a version obviously not allowing for the injection. Areas of application: simple micropiles for transferring modest loads at depth, anchors for structures, anchoring pilots for excavation fronts for applications of naturalistic engineering, making of "earths" for electrical installations that can easily be fixed in any type of ground, support for signage and traffic signs, etc. <IMAGE>
