Abstract: A ground anchor is composed of a number of components and is firmly held in position in the ground by its components being moved apart and firmly urged onto the wall of the cavity in which the ground anchor is positioned.
Abstract: For the progressive transfer of a tension or traction force from a fiber-reinforced plastic anchoring rod 10 to a threaded sleeve 20 surrounding one end of the rod, sawtooth shaped teeth are provided. The inclined flanks 6 of the teeth are increasingly longer as a function of the distance from the end 22 of the rod. The tooth length extension corresponds to the expansion of the rod under the local traction force which, because it becomes lower at each flank, decreases on a step-by-step basis. With this arrangement the rod can be stressed up to its breaking load without causing any damage to the threaded sleeve. This connection is suitable for any staying to fasten a cable to an anchoring element.
Abstract: In the installation of a roof bolt in the roof of a mine, a hole is driven vertically upwards into the rock above the mine roof and the bolt is pushed up the hole. Moist grit is blown up the annular gap around the shank of the bolt and packs into the gap to anchor the bolt in place. The air can escape from the bottom of the hole. The bolt may be tubular and form a duct for escaping air. When the gap is full of grit a sealing washer is pushed into the bottom part of the hole. A roof plate is located against the roof and held in place by a nut screwed to the projecting lower end portion of the bolt.
Abstract: An expansion body for constructions like piles or anchorages located in the earth, said body being adapted for insertion into the ground in a compact shape and expanded therein to an expanded shape.

A rigid plate is transversely affixed on the lower end portion of the elongate member. When the elongate member is driven generally upright into the earth, the plate extends through the earth in a direction generally perpendicular to lateral forces acting on the front or back surface of the elongate member. The pile can be used as an upright support member for an earth embankment wall.
Abstract: Mechanisms for joining two telescopic cylinders underwater in a temporary and inexpensive manner are disclosed, particularly when used in anchoring piles or in offshore tower legs. A gun fires projectiles radially from internally of the pile formed of telescopic cylinders to form the plurality of outwardly extending anchoring bumps in the walls of the cylinders. The projectiles are fired in a horizontal plane radially outwardly and from within and normal to the two telescopic cylinders underwater, for example, with two bumps being formed by each projectile, which bumps overlie each other tightly prior to their being penetrated by the projectile which holds the two bumps together. A number of radiating guns form a like number of pairs of bumps in a circle around the periphery of the telescopic cylinders to form an efficient, inexpensive, and simple temporary connection holding the two cylinders together.
