Anchoring means of a type known as "earth anchors", intended to facilitate anchoring against tensile forces below a ground surface or a bottom surface. The anchoring means includes at least one conical expandable tubular member (2), arranged attached at the end portion having a smaller cross-section area against a central and embraced rod or axle-shaped part (1), the end portion of said rod or axle-shaped part (1) against which the conical tubular member (2) is attached being arranged to serve as a first and preferably pointed part, arranged to facilitate penetration down through a ground or bottom surface. The opposed end portion of said rod or axle-shaped part (1) is arranged to facilitate attachment of a second member, such as a wire, tie-rod or similar, which second member is intended to be anchored by the anchoring means. The anchoring means is attached by pressing same down through a ground surface or bottom surface, thereafter by means of a pulling action being returned towards said surface, simultaneously expanding the conical tubular member (2) by means of surrounding material entering into same. Said return movement is performed for such a distance, that achieved expansion results in accomplishment of desired attachment or anchoring properties. |
