摘要:
A ground- or soil anchor is prepared and placed in the ground by drilling a bore hole at the chosen site by means of a drilling assembly which comprises an elongated tubular member (1) which serves as a drive shaft for the drill (8), which latter has a tapering rear end and is designed to be pulled into the said tubular member (1), the leading end of which is split so that the parts thereof - on the drill being pulled into it are spread apart and are eventually embedded in grout inserted into the bore hole.

Die Erfindung betrifft ein Verfahren zum Verankern eines Ankers im Erdreich mittels Bodengefrieren. Um einen Anker auf einfache und kostengünstige Weise sicher im Erdreich verankern zu können, wird vorgeschlagen, nach dem Ein bringen des Ankers in das Erdreich ein tiefkaltes Fluid über den Anker in Wärmetausch mit dem den Anker umgebenden Erdreich zu bringen.

In den Erdboden einschraubbare Haltevorrichtung zum Halten von Stützelementen, wie Pfählen, Stangen, Seilhaltern od. dgl., bestehend aus einem Aufnahmerohr mit einer Boh rung für die Aufnahme von Stützelementen, das an seinem un teren Ende eine Spitze aufweist, an die sich nach oben ein Schraubteil anschließt, der sich in einen als kegeligen Anpreß teil ausgebildeten Oberteil fortsetzt, dessen oberes Ende zur Anwendung von Werkzeugen für das Einschrauben in den Erd boden ausgebildet ist und der nach unten mit einem Bund als Begrenzung für das Einschrauben in den Erdboden versehen ist, unter den die Bohrung in das Aufnahmerohr wenigstens reicht.
摘要:
A ground anchor (10) for channel posts (11) has an angle iron leg (19) driven into the ground with a creased upright fin shroud strip (21) embracing the apex or corner (26) of the angle iron (19) at the trailing end of the leg (19) and secured to the ends (27) of the sides (25) of the angle iron (19) providing a V-shaped socket (29). The channel post (11) straddles the angle iron (19) with its side legs (15) bottomed on the sides (25) of the angle iron (19) and a compression member (31) bottomed on the strip (21) forces the channel post (11) against the angle iron (19) to spread the legs (15) of the post (11) into tight gripping relation with the angle iron (19) locking the post (11) in the socket (29). The socket (29) is open-ended and the post (11) can slide over the angle iron leg (19) to any desired depth so that a sign (12) mounted on top of the post (11) can be positioned at a selected height above the ground. The angle iron (19) is driven into the ground to a depth sufficient to bury the shroud strip (21) so that the post (11) is the only portion of the assemply projecting above the ground. The spreading of the legs (15) of the post (11) places them under tension so that when the post (11) is struck by a vehicle it will only bend at the impact zone, but will shear at the tensioned zone so that no metal will project above ground.

An expansion body for constructions like piles or anchorages located in the earth is adapted for insertion into the ground in a compact shape and expanded therein to an expanded shape. The expansion is achieved by unfolding a folded metallic casing (11) by filling it up with pressurized fluid. Each end of the elongated body is sealed by a closure comprising a socket (16, 17) with a sleeve (18, 19) encircling the near end part of the casing and a bottom plate (20, 21) with spacing means (22, 23) projecting into the inside of the casing. The sleeve (18,19) and spacing means (22, 23) define an annular space (26, 27) in which the end parts (14, 15) are kept in a folded position when the body is expanded.
摘要:
A method of arranging a ground anchor in the ground, said anchor comprising a shank and at least one helically extending blade on the outer side of said shank, the shank with the blade being screwed into the ground wherein after the ground anchor is screwed into the ground, air or gas isfirst injected into the ground surrounding the blade, after which a hardening fluid is injected.
