摘要:
L'invention concerne une machine (10) pour la réalisation de colonnes dans un sol, du type comportant un porteur (12) muni d'un mât (14) s'étendant selon une direction longitudinale ; un chariot mobile (16) monté coulissant le long du mât (14) ; un outil de perforation de sol (20), s'étendant selon un axe longitudinal parallèle à ladite direction longitudinale et solidaire dudit chariot mobile, présentant une extrémité supérieure reliée à des moyens d'alimentation en un matériau de construction, et une extrémité inférieure munie d'un orifice (28) pour l'injection du premier matériau de construction ; un système d'entraînement en rotation (18) de l'outil de perforation (20) ; et un corps (40) s'étendant autour de l'outil de perforation (20) de sorte que l'outil de perforation est apte à coulisser au travers dudit corps. Selon l'invention, la machine comprend un système de solidarisation (60) en translation et en rotation du corps (40) avec l'outil de perforation (20).
摘要:
A pile driving installation comprises a mast (2) for supporting a pile (30) as well as a vibration device (1), which vibration device (1) comprises vibrators (3), a frame (4) which is slidable along the mast, as well as clamping means (5) comprising at least one set of clamping jaws (7). The clamping jaws are pivotable with respect to each other and at one end are connected to each other through an actuator (17) for transferring the clamping jaws between an open position for allowing the vibration device and the pile to slide along each other, and a closed position for clamping the vibration device onto the pile. The vibrators are rigidly connected to the clamping jaws and the clamping jaws are resiliently supported with respect to the frame.

The invention relates to a method for producing ground columns (28, 86, 88) to support building or travelling loads, wherein a tubular encasing (10) is driven into the ground in a stationary zone, the ground material is removed from the tubular encasing (10), a sheathing (16) made of geotextile material is inserted into the tubular encasing (10) and filled with a load-bearing, granulated, loose material (24), the load-bearing material (24) is subsequently compacted and the tubular encasing (10) is removed. An individual jacket tube for each ground column (28, 86, 88) is driven into the ground, the jacket tube (10) is emptied by excavation, a sack-like sheathing (16) with a diameter that is larger than the diameter of the inner diameter of the tubular jacket (10) is introduced into the empty jacket tube (10) and the granulated material (24) progressively presses the sheathing (16) against the stationary supporting layer and the inner wall of the tubular jacket (10) during filling. The granulated material (24) is so compacted upon removal of the jacket tube (10) that the sheathing (16) extends beyond its original diameter until the opposing forces produced by the compacted ground around it are approximately balanced out. The material of the sheathing (16) is endowed with sufficient penetrability qualities so that no surrounding earth can penetrate into the column (28, 86, 88) thus formed.

Die Abmeldung betrifft eine Vorrichtung (10) und ein Verfahren zum Herstellen einer Füllgutsäule aus einem Füllmaterial im Boden, mit einem Verdrängerrohr (12), welches eine untere Austrittsöffnung zum Austreten des Füllmaterials aufweist, und einer Verschlusseinrichtung (20), welche an der Austrittsöffnung angeordnet ist und zwei Verschlussklappen (22) aufweist, welche an einem gemeinsamen Quersteg (40) verschwenkbar zwischen einer Verschlussposition und einer Öffnungsposition angelenkt sind, wobei das untere Ende des Verdrängerrohres (12) als eine sich nach unten verjüngende Verdrängerspitze (30) ausgebildet ist, wobei der Quersteg (40) in einem unteren spitzen Bereich der Verdrängerspitze (30) angeordnet ist und sich mittig und quer in dem Verdrängerrohr (12) erstreckt und wobei sich die Verschlussklappen (22) in der Verschlussposition zum Bilden der Verdrängerspitze (30) vom Quersteg (40) schräg nach oben erstrecken.
摘要:
The present invention relates to reinforcement of underground foundation, and in particular to a soil stabilization column comprising an essentially cylindrical portion comprising a mixture of soil and a stabilizing agent, and a center portion extending at least partly along the essentially cylindrical portion and comprising a cured load bearing stabilizing slurry, wherein the essentially cylindrical portion and the center portion are arranged concentrically to each other. The present invention further relates to a rotary device and method for forming such soil stabilization column.
