Extraction device for driving holes in soil

摘要

The device comprises an impaction mechanism 1 with a rope 3 secured on its neck 2 and connected to a pulling member 8. A ring 5 is incorporated in the neck 2, axially in relation thereto, so that a gap is left between the ring 5 and the neck 2. Arranged in the gap there is an elastic element 6 with channels 7 through which the ends of the rope 3 are guided. The inside of the neck 2 is designed with abutments 9 in which channels 10 are formed for passage of the ends of the rope 3. The ring 5 can be designed with end abutments 14 with channels 15, which contributes to the neck 2 being supported more reliably by the impaction mechanism 1. The device according to the invention can preferably be used for driving holes in loose and water-soaked soil.
